other | Biogenic substance | ||||||
other | A biogenic substance is a product made by or of life forms. | ||||||
other | The term encompasses constituents, secretions, and metabolites of plants or animals. | ||||||
other | In context of molecular biology, biogenic substances are referred to as biomolecules. | ||||||
other | An abiogenic substance or process does not result from the present or past activity of living organisms. | ||||||
other | Abiogenic products may, e.g., be minerals, other inorganic compounds, as well as simple organic compounds (e.g. | ||||||
other | extraterrestrial methane, see also abiogenesis). | ||||||
other | Biogenic amine | ||||||
other | A biogenic amine is a biogenic substance with one or more amine groups. | ||||||
other | They are basic nitrogenous compounds formed mainly by decarboxylation of amino acids or by amination and transamination of aldehydes and ketones. | ||||||
other | Biogenic amines are organic bases with low molecular weight and are synthesized by microbial, vegetable and animal metabolisms. | ||||||
other | In food and beverages they are formed by the enzymes of raw material or are generated by microbial decarboxylation of amino acids. | ||||||
other | Some prominent examples of biogenic monoamines include: | ||||||
other | Monoamine neurotransmitters | ||||||
other | Trace amines (endogenous amines that activate the human TAAR1 receptor) | ||||||
other | Tryptamines | ||||||
other | Other biogenic monoamines | ||||||
other | Examples of notable biogenic polyamines include: | ||||||
other | There is a distinction between endogenous and exogenous biogenic amines. | ||||||
other | Endogenous amines are produced in many different tissues (for example: adrenaline in adrenal medulla or histamine in mast cells and liver). | ||||||
other | The amines are transmitted locally or via the blood system. | ||||||
other | The exogenous amines are directly absorbed from food in the intestine. | ||||||
other | Alcohol can increase the absorption rate. | ||||||
other | Monoamine oxidase (MAO) breaks down biogenic amines and prevents excessive resorption. | ||||||
other | MAO inhibitors (MAOIs) are also used as medications for the treatment of depression to prevent MAO from breaking down amines important for positive mood. | ||||||
other | Biogenic amines can be found in all foods containing proteins or free amino acids and are found in a wide range of food products including fish products, meat products, dairy products, wine, beer, vegetables, fruits, nuts and chocolate. | ||||||
other | In non-fermented foods the presence of biogenic amines is mostly undesired and can be used as indication for microbial spoilage. | ||||||
other | In fermented foods, one can expect the presence of many kinds of microorganisms, some of them being capable of producing biogenic amines. | ||||||
other | They play an important role as source of nitrogen and precursor for the synthesis of hormones, alkaloids, nucleic acids, proteins, amines and food aroma components. | ||||||
other | However, food containing high amounts of biogenic amines may have toxicological effects. | ||||||
other | Biogenic amines are naturally present in grapes or can occur during the vinification and aging processes, essentially due to the microorganism's activity. | ||||||
other | When present in wines in high amount, biogenic amines may cause not only organoleptic defects but also adverse effects in sensitive human individuals, namely due to the toxicity of histamine, tyramine and putrescine. | ||||||
other | Even though there are no legal limits for the concentration of biogenic amines in wines, some European countries only recommend maximum limits for histamine. | ||||||
other | In this sense, biogenic amines in wines have been widely studied. | ||||||
other | The determination of amines in wines is commonly achieved by liquid chromatography, using derivatization reagents in order to promote its separation and detection. | ||||||
other | In alternative, other promising methodologies have been developed using capillary electrophoresis or biosensors, revealing lower costs and faster results, without needing a derivatization step. | ||||||
other | It is still a challenge to develop faster and inexpensive techniques or methodologies to apply in the wine industry. | ||||||
other | Sugar River (Wisconsin) | ||||||
other | The Sugar River is a tributary of the Pecatonica River, approximately long, in the U.S. states of Wisconsin and Illinois. | ||||||
other | It rises in the hills of southwest Wisconsin, in southwest Dane County, approximately southwest of Madison. | ||||||
other | The headwaters are at the southern terminus of the last North American glacier. | ||||||
other | West of the river, the land elevates from lack of glaciation and joins what is known as the "driftless area", known for its abrupt hills and valleys, covering most of southwest Wisconsin. | ||||||
other | From its source, the river meanders southeast, past Paoli and Belleville, where it is dammed to form Lake Belle View. | ||||||
other | From there it meanders east of Monticello where it is joined by the Little Sugar River and flows south through Albany, and Brodhead. | ||||||
other | It crosses into northern Illinois flowing past an extensive area of the Forest Preserves of Winnebago County system. | ||||||
other | These preserves are Sugar River Alder, Colored Sands, and Sugar River. | ||||||
other | The river joins the Pecatonica River in northern Winnebago County near Shirland, approximately south of the state line and approximately north-northwest of Rockford. | ||||||
other | The Sugar River State Trail is a abandoned railroad line used for walking, bicycling, snowmobiling, and cross-country skiing. | ||||||
other | Two organizations have been established to protect the watershed around the upper and lower stretches of the Sugar River. | ||||||
other | The Upper Sugar River Watershed Association manages the watershed north of Belleville and the Lower Sugar River Watershed Association manages the watershed south of Albany. | ||||||
other | The area in between, the Middle Sugar River Watershed, does not have an established organization. | ||||||
other | David M. Walker (astronaut) | ||||||
other | David Mathieson "Dave" Walker (May 20, 1944 – April 23, 2001), (Capt, USN), was an American naval officer and aviator, fighter pilot, test pilot, and a former NASA astronaut. | ||||||
other | He flew aboard four Space Shuttle missions in the 1980s and 1990s. | ||||||
