Peptide bond

/ˈpɛptaɪd bɑnd/ noun

Definition

A covalent chemical bond that links amino acids together in proteins, formed when the carboxyl group of one amino acid reacts with the amino group of another. This bond is also called an amide bond.

Etymology

From Greek 'peptos' meaning 'digested' or 'cooked,' combined with 'bond.' The term 'peptide' was coined by German chemist Emil Fischer in 1902, referring to the products of protein digestion.

Kelly Says

Peptide bonds are like the rivets that hold proteins together—they're incredibly strong and create the backbone of every protein in your body! Breaking these bonds is exactly what happens when you digest food, turning proteins back into individual amino acids.
