Threonine is one of the 20 most common natural amino acids on Earth. Nutritionally, in humans, threonine is also an essential amino acid.
Threonine contains two chiral centers, so there are four possible stereoisomers of threonine. It means that there are two possible diastereomers of L-threonine. However, name L-threo... | <urn:uuid:e3f9f316-f7f2-4a6e-a591-59bc984bfede> | 3.125 | 222 | Knowledge Article | Science & Tech. | 34.4227 |
