Fast-atom bombardment mass spectra of some pentapeptides related to natural enkephalins. 1986

A F Casy

The mass spectral features of four diastereoisomeric pairs of peptides related to the enkephalins recorded under fast-atom bombardment conditions are presented and shown to provide evidence of molecular weight and amino acid content and sequence.

UI	MeSH Term	Description	Entries
D009842	Oligopeptides	Peptides composed of between two and twelve amino acids.	Oligopeptide
D004745	Enkephalins	One of the three major families of endogenous opioid peptides. The enkephalins are pentapeptides that are widespread in the central and peripheral nervous systems and in the adrenal medulla.	Enkephalin
D000595	Amino Acid Sequence	The order of amino acids as they occur in a polypeptide chain. This is referred to as the primary structure of proteins. It is of fundamental importance in determining PROTEIN CONFORMATION.
