In peptide formation, `-NH_(2)` group of one molecule condenses with

Options

A. `-COOH` group of same molecule
B. `-COOH` group of another molecule
C. `-COCl` group of another molecule
D. `-NH_(2)` group of another molecule

Answer

B

Explanation

`alpha` amino acids combines as
`H_(2)N-overset(R)overset(|)CH-COOH+H_(2)N-overset(R)overset(|)Ch-COOH to H_(2)N-overset(R)overset(|)CH-CO-NH-overset(R)overset(||)C-OH`
Hence `-NH_(2)` group of one molecule condenses with `-COOH` group of another molecules.
