The term "peptide" originates from the Greek word "péssein," meaning "to digest." A peptide is a compound formed by amino acids linked through peptide bonds. Peptide bonds arise from the dehydration condensation between the alpha-carboxyl group of one amino acid and the alpha-amino group of another. Classified by amino acid count, peptides with 2 to 20 amino acids are termed oligopeptides, those with 20 to 50 are polypeptides, and sequences exceeding 50 amino acids with specific spatial structures are generally categorized as proteins. Peptides typically have a molecular weight below 10 kDa.

A peptide bond is a characteristic covalent bond in protein molecules, formed through a dehydration condensation reaction between the alpha-carboxyl group (alpha-COOH) of one amino acid and the alpha-amino group of an adjacent amino acid. Its chemical nature is an amide bond.

Peptide synthesis refers to the process of constructing amino acid sequences and forming amide bonds (peptide bonds) through chemical or biological means, essentially enabling the artificial construction of oligopeptide or polypeptide molecules with specific biological functions. As a critical branch of bioorganic chemistry, this technology focuses on the selective activation of amino acid monomers, directional conjugation, and precise control of sequence assembly.

Peptide solubility refers to the maximum amount of peptide that can dissolve in a unit volume of solvent under specific temperature and pH conditions, typically characterized by mass concentration (g/L) or molar concentration (mol/L). It directly influences preparation technology, storage stability, and clinical application efficacy of peptide-based drugs.

Amino acids are organic compounds containing an alpha-amino group (alpha-NH2) and an alpha-carboxyl group (alpha-COOH), with the general formula RCH(NH2)COOH. The alpha-carbon atom is linked to a specific side-chain group, forming the fundamental structural units of biological macromolecules.
