Key Concepts

Amino Acid Structure

Amino acids are the building blocks of proteins, each containing an amino group (–NH2), a carboxyl group (–COOH), a hydrogen atom, and a variable side chain (R group) attached to a central carbon. This general structure allows them to link together, forming the backbone of protein structures.

Peptide Bond Formation

A peptide bond is formed during a condensation or dehydration synthesis reaction between the carboxyl group of one amino acid and the amino group of another. This reaction releases a water molecule and creates a covalent bond that connects the amino acids into a polypeptide chain.

Peptide Bond Structure

The peptide bond is characterized by a covalent linkage between the carbonyl carbon of one amino acid and the nitrogen of the amide group of another. It exhibits resonance stabilization, which gives it a partial double bond character, leading to planarity around the bond and influencing the overall conformation of the protein.
