Seliwanoff's test is used to distinguish aldose
and ketose.
<br><br>When Seliwanoff's reagent added to a solution containing ketoses, red colour is formed rapidly indicating a positive test.
<br>While in case of aldose, a slower forming light pink colour observed.

Maltose on treatment with dilute HCI gives :
|
[{"identifier": "A", "content": "D-Galactose"}, {"identifier": "B", "content": "D-Glucose and D-Fructose"}, {"identifier": "C", "content": "D-Glucose"}, {"identifier": "D", "content": "D-Fructose"}]
|
["C"]
| null |
Maltose on treatment with dil. HCl gives D-glucose. Hydrolysis of
maltose yields two moles of $$\alpha $$- D-glucose. Thus, it is composed of two $$\alpha $$-D-glucose units in
which C-1 of one glucose unit (I) is linked to C-4 of another
glucose unit (II). The free aldehyde group can be produced at C-1
of second glucose in solution and it shows reducing properties.
<br>So, it is a reducing sugar.<br><br>

<p>Let's analyze the given statements:</p>
<p>Assertion A: "Amylose is insoluble in water." This statement is incorrect. Amylose is actually soluble in water, although its solubility is lower compared to other carbohydrates like amylopectin.</p>
<p>Reason R: "Amylose is a long linear molecule with more than 200 glucose units." This statement is correct, as amylose is indeed a linear polysaccharide made up of glucose units.</p>
<p>Given this information, the correct option is:</p>
<p>Option D: $\mathbf{A}$ is not correct but $\mathbf{R}$ is correct.</p>

Seliwanoff 's test is a differentiating test for Ketose
and aldose. This test relies on the principle that the
keto hexose are more rapidly dehydrated to form
5-hydroxy methyl furfural when heated in acidic
medium which on condensation with resorcinol,
Cherry red or brown red coloured complex is
formed rapidly indicating a positive test.

<p>Number of compounds from the following which will not produce orange red precipitate with Benedict solution is ___________.</p>
<p>Glucose, maltose, sucrose, ribose, 2-deoxyribose, amylose, lactose</p>

Benedict's solution is a reagent that tests for reducing sugars. A reducing sugar is one that has a free aldehyde or ketone group, which can reduce the copper(II) ions in Benedict's reagent to copper(I) oxide, which forms a brick-red or orange-red precipitate.
<br/><br/>Given the compounds :
<br/><br/>1. Glucose - is a reducing sugar, as it has a free aldehyde group.
<br/><br/>2. Maltose - is a reducing sugar. It has a free anomeric carbon that can form an aldehyde group.
<br/><br/>3. Sucrose - is not a reducing sugar. Its glycosidic bond locks the anomeric carbons, preventing them from forming an aldehyde or ketone.
<br/><br/>4. Ribose - is a reducing sugar, as it has an aldehyde group.
<br/><br/>5. 2-deoxyribose - is a reducing sugar. It has a free anomeric carbon that can form an aldehyde group.
<br/><br/>6. Amylose - is a polysaccharide and does not typically behave as a reducing sugar in Benedict's test. Even though one end of the amylose chain can technically open to reveal an aldehyde group (the so-called reducing end), the reaction would likely be much less dramatic than with true reducing sugars, and might not occur at all under typical test conditions.
<br/><br/>7. Lactose - is a reducing sugar, as it has a free anomeric carbon that can form an aldehyde group.
<br/><br/>Hence, out of the seven compounds listed, sucrose and amylose will not likely produce an orange-red precipitate with Benedict's solution. Thus, the number of compounds that will not produce an orange-red precipitate with Benedict's solution is 2.

<p>The incorrect statement about Glucose is :</p>
|
[{"identifier": "A", "content": "Glucose remains in multiple isomeric form in its aqueous solution\n"}, {"identifier": "B", "content": "Glucose is soluble in water because of having aldehyde functional group\n"}, {"identifier": "C", "content": "Glucose is an aldohexose\n"}, {"identifier": "D", "content": "Glucose is one of the monomer unit in sucrose"}]
|
["B"]
| null |
<p>Let's analyze each statement to identify the incorrect one about glucose.</p>
<p><strong>Option A:</strong> Glucose remains in multiple isomeric forms in its aqueous solution. This statement is <strong>correct</strong>. Glucose exists in equilibrium with various isomeric forms in solution, including its linear form and two cyclic forms (alpha and beta anomers) that result from the formation of a hemiacetal bond within the molecule itself. The interconversion between these forms is known as mutarotation.</p>
<p><strong>Option B:</strong> Glucose is soluble in water because of having an aldehyde functional group. This statement is <strong>incorrect</strong> though it might seem partially true at first glance. While the aldehyde group can participate in hydrogen bonding, the primary reason glucose is highly soluble in water is due to its multiple hydroxyl (-OH) groups that can form hydrogen bonds with water molecules. The ability to form numerous hydrogen bonds makes glucose highly water-soluble, not just the presence of an aldehyde group.</p>
<p><strong>Option C:</strong> Glucose is an aldohexose. This statement is <strong>correct</strong>. Glucose is classified as an aldohexose because it contains an aldehyde group (-CHO) on its first carbon and has a total of six carbon atoms, making it a hexose sugar.</p>
<p><strong>Option D:</strong> Glucose is one of the monomer units in sucrose. This statement is <strong>correct</strong>. Sucrose is a disaccharide composed of two monomers: glucose and fructose. Thus, glucose is indeed one of the monomer units in sucrose.</p>
<p>In summary, the <strong>incorrect</strong> statement about glucose is <strong>Option B</strong>: Glucose is soluble in water because of having an aldehyde functional group. The primary reason for its solubility in water is the hydroxyl groups' ability to form extensive hydrogen bonding, not solely the presence of an aldehyde functional group.</p>

<p>$$\alpha$$-Glucose and $$\alpha$$-Galactose differ in configuration of one asymmetric carbon. Thus they are epimers.</p>
<p>$$\alpha$$ and $$\beta$$-glucose differ at anomeric carbon. Thus they are anomers.</p>
<p>$$\alpha$$-Glucose and $$\alpha$$-Fructose have different functional groups. Thus they are functional isomers.</p>

The secondary structure of a protein refers to the shape in which a long peptide chain can exist. There are two different conformations of the peptide linkage present in protein, these are $$\alpha $$-helix and $$\beta $$-conformation. The $$\alpha $$-helix always has a right handed arrangement. In $$\beta $$-conformation all peptide chains are streched out to nearly maximum extension and then laid side by side and held together by intermolecular hydrogen bonds. The structure resembles the pleated folds of drapery and therefore is known as $$\beta $$-pleated sheet.

<br><br>Where p<sup>Ka</sup> of Aliphatic amino group is 9.4 and p<sup>Ka</sup> of basic nitrogen of imidazole ring is 5.8.
<br><br>As more p<sup>Ka</sup> value means more basic, So, aliphatic amino group is more basic.
<br><br>As pH of blood is 7.4 so p<sup>Ka</sup> of blood is < 7.4. So, $$-$$NH<sub>2</sub> group will act as more basic compare to blood. So, blood will act as acid and donate H<sup>+</sup> to $$-$$NH<sub>2</sub> group.

<p>The reaction of $\alpha$-halocarboxylic acid with dilute ammonia is known as the haloform reaction. In this reaction, the halogen atom of $\alpha$-halocarboxylic acid is replaced by an amino group to form $\alpha$-amino carboxylic acid. The yield of $\alpha$-amino carboxylic acid is good because the amino group is a better nucleophile than the halogen atom, and it attacks the carbonyl carbon of the carboxylic acid to form an intermediate, which is then hydrolyzed to form the product. On the other hand, when alkyl halides are reacted with ammonia, the yield of amines is very low because alkyl halides are less reactive than $\alpha$-halocarboxylic acids.</p>
<p>The reason (R) is also true. Amino acids exist in the zwitterion form in an aqueous medium. In this form, the amino group has a positive charge, and the carboxyl group has a negative charge. The zwitter ion form is stabilized by the interaction between the opposite charges, which is known as an electrostatic interaction. This interaction makes the zwitterion form more stable than the neutral form.</p>

<p>Total number of tripeptides possible by mixing of valine and proline is ___________</p>
|
[]
| null |
8
|
<p>To calculate the total number of tripeptides possible by mixing valine and proline, we need to use the fundamental principle of counting.</p>
<p>Since a tripeptide is made up of three amino acids, and we have two choices for each position (either valine or proline), we can use the multiplication principle to find the total number of possible tripeptides.</p>
<p>That is, the total number of tripeptides possible by mixing valine and proline is:</p>
<p>2 x 2 x 2 = 8</p>
<p>Therefore, there are a total of 8 possible tripeptides that can be formed by mixing valine and proline.</p>

<p>The stabilization of secondary (2°) and tertiary (3°) structures of proteins mainly involves interactions such as disulfide bridges (S-S linkages), van der Waals forces, hydrogen bonding, and hydrophobic interactions.</p>
<p><b>Option A</b>: O-O linkage is not usually involved in the stabilization of protein structures. Oxygen-oxygen single bonds are generally unstable and rarely observed in nature. </p>
<p><b>Option B</b>: S-S linkage (disulfide bridges) between cysteine residues in a protein can help stabilize the protein's structure, particularly its tertiary structure.</p>
<p><b>Option C</b>: Van der Waals forces can contribute to the stabilization of protein structures, particularly in the interior of the protein where they can promote hydrophobic interactions.</p>
<p><b>Option D</b>: Hydrogen bonding can play a critical role in the formation and stabilization of secondary structures such as alpha-helices and beta-sheets.</p>
<p>Therefore, the correct answer is Option A (-O-O- linkage).</p>

Isoleucine is an $\alpha$-amino acid that is used in the biosynthesis of proteins. It contains an $\alpha$ amino group, an $\alpha$-carboxylic acid group, and a hydrocarbon side chain with a branch. It is classified as a non-polar, uncharged, branchedchain, aliphatic amino acid.<br><br>
Lysine is an $\alpha$-amino acid that is a precursor to many proteins. It contains an $\alpha$-amino group, an alpha-carboxylic acid group, and a side chain lysyl, classifying it as a basic, charged, aliphatic amino acid. It is encoded by the codons AAA and AAG. Glutamic acid is an amino acid used to form proteins.<br><br>
Cysteine and methionine are sulphur containing amino acids. Amino acids get linked to one another by peptide bond formation and form a polypeptide chain of proteins. Hence cysteine and methionine are found in several proteins.<br><br>
(a) isoleucine<br><br>

<p>Which structure of protein remains intact after coagulation of egg white on boiling?</p>
|

["B"]
| null |
<p>The structure of protein that remains intact after the coagulation of egg white on boiling is the <strong>Primary</strong> structure. The correct answer is Option B.</p>
<p>The primary structure of a protein is the sequence of amino acids that are linked by peptide bonds. This sequence dictates the protein's higher levels of structure including secondary, tertiary, and quaternary structures. Regardless of the change in the protein's conformation due to denaturation (such as what happens during boiling of egg white), the sequence of amino acids remains the same since the peptide bonds do not get broken under such conditions.</p>
<p>When egg white is boiled, the proteins denature, which means the structure of the protein becomes altered due to the breakdown of non-covalent interactions that hold the protein's higher-order structures together. This includes:</p>
<ul>
<li><strong>Secondary structure</strong>: This involves hydrogen bonding within the peptide backbone, producing structures such as alpha-helices and beta-sheets.</li>
<br/><li><strong>Tertiary structure</strong>: This involves the overall three-dimensional folding of the protein, driven by interactions such as hydrogen bonds, ionic bonds, hydrophobic interactions, and disulfide bridges.</li>
<br/><li><strong>Quaternary structure</strong>: This involves the arrangement and interactions of multiple protein subunits in a multi-subunit complex.</li>
</ul>
<p>During coagulation caused by heat, the weak hydrogen and ionic bonds of secondary and tertiary structures are broken and the proteins can aggregate or form gel-like structures, changing the consistency of the egg white. However, the covalent peptide bonds of the primary structure stay intact throughout this process.</p>

|
["A"]
| null |
<p>The coagulation of an egg on heating is because of <strong>Option A: Denaturation of protein occurs</strong>. When an egg is heated, the proteins in the egg (primarily albumins) undergo denaturation. This process involves the structural alteration of the protein molecules without breaking the peptide bonds that hold the amino acid sequences together. Denaturation causes the proteins to unfold and then aggregate into a new, solid structure, which is what you observe as the egg white and yolk changing from liquid to solid. This change is principally caused by the disruption of non-covalent bonds in the protein, such as hydrogen bonds, ionic bonds, and hydrophobic interactions.</p>
<p>Option B is incorrect because the biological property of the protein does indeed change during the process. The protein in its denatured (coagulated) form does not function in the same way as it did in its native form.</p>
<p>Option C is also incorrect because the primary structure of the protein, defined by its amino acid sequence linked by peptide bonds, remains unaltered during denaturation. The process does not involve the breaking of these peptide linkages.</p>
<p>Lastly, Option D is incorrect because the secondary structure of the protein, which includes α-helices and β-pleated sheets formed by hydrogen bonding, typically undergoes significant alteration during denaturation, contributing to the observable change in the egg's texture.</p>
