Statement $- I$ is false but Statement $- II$ is true.

Vedclass · Answer

(D) Statement $- I$ is false because there are many amino acids that are not involved in protein synthesis,such as ornithine,citrulline,and $\gamma$-aminobutyric acid $(GABA)$.Statement $- II$ is true because the general structure of an amino acid consists of a central $\alpha$-carbon atom bonded to an amino group $(-NH_2)$,a carboxyl group $(-COOH)$,a hydrogen atom,and a variable side chain known as the $R-$group. The $R-$group determines the specific properties of each amino acid.

Statement $- I :$ All amino acids are protein-forming amino acids.
Statement $- II : R-$ group is a variable group in an amino acid.
