A molecule consisting of 2 or more amino acids. Peptides are smaller than proteins, which are also chains of amino acids. Molecules small enough to be synthesized from the constituent amino acids are, by convention, called peptides rather than proteins. The dividing line is at about 50 amino acids. Depending on the number of amino acids, peptides a [..]

A molecule that contains two or more amino acids (the molecules that join together to form proteins). Peptides that contain many amino acids are called polypeptides or proteins.

A short polymer made by linking together amino acid molecules.

A compound made up of a group of amino acids; aids in the digestion of certain proteins

a protein with a small number of amino acids.

1906, from German peptid; see peptone + -ide, probably indicating a derivative.

A peptide is one or more amino acids linked by chemical bonds. The term also refers to the type of chemical bond that joins the amino acids together. A series of linked amino acids is a polypeptide. The cell's proteins are made from one or more polypeptides.

Any compound consisting of two or more amino acids, the building blocks of proteins.

A small polymer usually containing fewer than 30 amino acids connected by peptide bonds.

Peptides are the building blocks of life on earth. Proteins are peptides. Peptides (and therefore proteins) are made from building blocks called amino acids joined together in strings. In scientific s [..]
