Peptide bond
A covalent chemical bond formed between the carboxyl group of one amino acid and the amino group of another through a condensation reaction. Peptide bonds link amino acids into peptide chains.

Related Terms
An organic molecule containing both an amino group (-NH2) and a carboxyl group (-COOH). The 20 standard amino acids are the building blocks of peptides and proteins, linked together by peptide bonds.
Primary structureThe linear sequence of amino acids in a peptide, representing the most fundamental level of structural organization. All higher-order structure and function derive from the primary sequence.
Peptide synthesisThe chemical process of creating peptides by linking amino acids together. Can be performed in solution or on solid phase. Commercial peptides are almost exclusively made via solid-phase peptide synthesis (SPPS).
