Vedclass · Answer

(B) Step $1$: Statement $A$ is correct. Naturally occurring $\alpha$-amino acids in proteins are of the $L$-configuration.Step $2$: Statement $B$ is correct. By definition, amino acids contain at least one amino group $(-NH_2)$ and one carboxylic acid group $(-COOH)$.Step $3$: Statement $C$ is incorrect. Amino acids can be acidic (more $-COOH$ than $-NH_2$, e.g., aspartic acid) or basic (more $-NH_2$ than $-COOH$, e.g., lysine).Step $4$: Statement $D$ is correct. The name 'Tyrosine' is derived from the Greek word 'tyros', meaning cheese, as it was first isolated from casein in cheese.Step $5$: Therefore, statements $A$, $B$, and $D$ are correct.
