morphiceptin

These are published properties of the molecule, given for identification. Values we cannot confirm are omitted rather than estimated. What these terms mean.

What this compound is

Four residues derived from milk protein, and one residue different again from endomorphin-2. Three closely related tetrapeptides sit together here.

Sequence

Morphiceptin amino-acid sequence in one-letter code, numbered by residue position
1YPFP
Three-letter code
Tyr-Pro-Phe-Pro

The one-letter code gives the amino-acid backbone. Terminal modifications, where a compound carries them, are accounted for in the molecular weight above but are not visible in the letters.

Residue composition

Counted directly from the sequence above. Morphiceptin is built from 3 of the twenty standard amino acids across 4 positions.
