One C-F bond as a dashed line; the other C-F bond as a wedge Structures 1 and 2 are identical, but Structures 3 and 4 are a pair of enantiomers. WebAnomeric carbon is a term used to describe the epimeric carbon in anomers. The cyclic structure exists in two different configurational forms. If the hydroxyl on the anomeric carbon is below the plane of the ring, it is said to be in the alpha position, if above the plane of the ring, it is in the beta position.

WebAn amino acid has the general formula H₂N-CH (R)-COOH, where R stands for the different acids. Notice that the central C atom is chiral — it has four different groups attached — so the molecule can exist as a pair of enantiomers (nonsuperimposable mirror images). One of these is the D isomer, and the other is L (i.e. a pair of R/S isomers).
