How many chiral carbons does threonine have

WebMay 4, 2016 · There are five chiral carbons in tetracycline. Explanation: The tetracyclines are a family of broad-spectrum antibiotics used to treat bacterial infections. The parent member of this family is tetracycline itself: The chiral centres are the carbon atoms with four different groups attached. Threonine is one of two proteinogenic amino acids with two stereogenic centers, the other being isoleucine. Threonine can exist in four possible stereoisomers with the following configurations: (2S,3R), (2R,3S), (2S,3S) and (2R,3R). However, the name L-threonine is used for one single stereoisomer, (2S,3R)-2-amino-3-hydroxybutanoic acid. The second stereoisomer (2S,3S), which is rarely present in nature, is called L-allothreonine. The two stereoisomers (2R,3S)- and (2R,3R)-2-a…

WebIn general, if you have a small molecule with no sp3 centers in the molecule, the molecule is planar. But there are many exceptions. Here are a few common ones: - Water is planar. The oxygen is sp3 but there are only 3 atoms so there's nothing to stick out of the HOH plane. - Allene is not planar.
