Small proteins in the body

a group of two or more amino acids used in conditioners and shampoos that form a layer on the hair shaft to make the hair look thicker.

Amino acid polymers in which the individual amino acid residues are linked by amide bonds.

Chains of amino acids; often portions of a protein molecule.

Mother Nature's secret to healthy, smooth, firm skin. They are the building blocks of proteins which make up skin's structure and are responsible for normal cell function.

Peptides are amides derived from two or more amino acids (the same or different) linked by peptide bonds. These bonds are formed by the reaction between adjancent carboxyl (-COOH) i amino (-NH2) groups with the elimination of water.

A compound consisting of two or several amino acids.

Chain structures that result when ammino acids condense to form one or more amide linkages.

A small fragment of a protein consisting of a short chain of protein building blocks, or amino acids, typically 4-10 protein amino acids long.

Organic compound composed of amino acids linked together chemically by peptide bonds

Short chains of amino acids.

any of various natural or synthetic compounds containing two or more amino acids linked by the carboxyl group of one amino acid to the amino group of another

Any combination of two or more amino acids linked together through amide bonds that are not a protein. Pieces of a protein produced by breaking chemical bonds on the protein.

Two or more amino acids chained together by a bond called a "peptide bond."

Peptides are the basic structural unit of collagen. The appearance of skin mainly depends on the Collagen structure, the most important protein family of the dermal connective tissue. Collagen is involved in a large array of biological functions including maintenance of structural integrity, cell adhesion, tissue remodeling, and skin repair. By prompting collagen synthesis, peptides contribute to decrease the visual appearance of wrinkles and increase skin firmness and thickness.

Chains of amino acids that can function as neurotransmitters or hormones.

Form the constituent parts of proteins. They contain amino acids and are a breakdown or buildup unit in protein metabolism.

Small protein-like compounds made of amino acid building blocks.

A family of molecules formed from the linking, in a defined order, of various amino acids. Some peptides have been used in cancer vaccines.

Two or more amino acids linked by a peptide bond.
