Question

Most of the naturally a - amino acids have: (A) D-configuration (B) L-configuration (C) Meso isomerism (D) Both (a) (b)

Tardigrade Admin · Accepted Answer

Except glycine, all amino acids have a chiral centre and almost all naturally occuring amino acid have L-configuration at the a-carbon. According to Cahn-Ingold-Prelog rules, R - group has a lower priority then -COOH, all amino acids have S configuration. <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/chemistry/646b183083383f51f7573c6196a7752d-.png" />

Both (a) & (b)

Except glycine, all amino acids have a chiral centre and almost all naturally occuring amino acid have L-configuration at the a-carbon. According to Cahn-Ingold-Prelog rules, R - group has a lower priority then $- COO H$ , all amino acids have S configuration.
