Abstract
Disclosed are opioid peptides recovered from hydrolysates of wheat proteins with an acid protease and further a neutral or alkaline protease. Of those peptides, the structure of four opioid peptides was identified by the amino acid sequence of Gly-Tyr-Tyr-Pro (SEQ ID NO: 1), Gly-Tyr-Tyr-Pro-Thr (SEQ ID NO: 2), Gly-Tyr-Tyr-Pro-Thr-Ser (SEQ ID NO: 3) or Tyr-Pro-Ile-Ser-Leu (SEQ ID NO: 4). They are useful as a medicine such as narcotic, analgesic or the like.
