polypeptide

noun ˌpɒlɪˈpɛptʌɪdˌpɑliˈpɛptaɪd

Biochemistry

A linear organic polymer consisting of a large number of amino-acid residues bonded together in a chain, forming part of (or the whole of) a protein molecule.
〔生化〕多肽，缩多氨酸
as modifier a polypeptide chain
Example sentencesExamples
- They both develop random transient beta-strands across the whole polypeptide chain.
- Unlike larger polypeptides and proteins, small nucleic acid duplexes and hairpins do not have a dense core to which this effect would apply.
- The LDL receptor is a polypeptide of 839 amino acids that spans the plasma membrane.
- These enzymes break down proteins into polypeptides and then into amino acids, which are absorbed through the gut wall into the bloodstream.
- It is a basic protein with a single polypeptide chain and acts on cellular and model lipid membranes.

Origin

Early 20th century: from poly- 'many' + peptone + -ide.
