Vedclass · Answer

(A) Alanine is an amino acid with the structure $CH_3-CH(NH_2)-COOH$.In an alkaline medium $(pH > 7)$,the carboxylic acid group $(-COOH)$ loses a proton $(H^+)$ to form a carboxylate ion $(-COO^-)$.Thus,the structure becomes $CH_3-CH(NH_2)-COO^-$,which carries a net negative charge.Therefore,in an alkaline medium,alanine exists predominantly as an anion.
