Question

Peptide bond is formed between.

• A. Two amino groups
• B. Carboxyl group and ketone group
• C. Amino group and carboxyl group
• D. Two carboxyl groups

Answer 1

The correct option is C Amino group and carboxyl group

A peptide bond is a chemical bond formed between two molecules when the carboxyl group of one molecule reacts with the amino group of the other molecule, releasing a molecule of water $H_{2}0$. This is a dehydration synthesis reaction (also known as a condensation reaction), and usually occurs between amino acids.
