WebBoth the left and right hand are chiral (ky-ral) and show chirality. Chiral is derived from the Greek word cheir, which means “hand”, and chirality means “handedness”. Figure 5.3a … 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).
