Sir ne jo esterification reaction karwayi thi usme carboxylic acid + alcohol → ester + water banta hai. Lekin agar carboxylic acid amino acid ke –NH₂ group ke saath react kare, to ester nahi banta, balki amide (peptide) bond banta hai aur H₂O nikalta hai. Yani amino acid ke saath wali reaction amide formation hoti hai, esterification nahi. سweرa شahبaz💝
