Which of the following is true about alpha amino acids?
Which of the following is true about alpha amino acids?
- A. If the amino group at the chiral carbon lies on the left hand side as in L-(-)-glyceride, the amino acid belongs to L-series
- B. If it is towards right as in D-(+)-glyceraldehyde, it is said to belong to D-series.
- C. Both of the above
- D. None of the above
Step-by-step solution
α-Amino acids are classified into L- or D-series based on the configuration of the chiral α-carbon relative to glyceraldehyde. In a Fischer projection, if the amino group (NH₂) is on the left, it corresponds to the L-series (like L-glyceraldehyde), and if on the right, to the D-series (like D-glyceraldehyde). Since both statements A and B correctly describe this relationship, option C is correct.
