Vedclass · Answer

(B) $\Rightarrow$ Amino acids are organic compounds containing an amino group and an acidic group as substituents on the same carbon,i.e.,the $\alpha$-carbon. Hence,they are called $\alpha$-amino acids.$\Rightarrow$ There are four substituent groups occupying the four valency positions of the $\alpha$-carbon. These are hydrogen,a carboxyl group,an amino group,and a variable group designated as the $R$ group.$\Rightarrow$ Based on the nature of the $R$ group,there are many amino acids,but only $20$ types of amino acids are commonly found in the proteins of living organisms.
