The primary structure identification of a corn peptide facilitating alcohol metabolism by HPLC-MS/MS

► The structure of corn peptides (CPs) with facilitating alcohol metabolism activity was researched. ► The primary structure of the CPs was preliminarily identified by HPLC-MS/MS. ► Then it was further identified by comparing with zein sequence in the MS database. ► It was a pentapeptide - Q-L-L-P-F. ► Its ability to facilitate alcohol metabolism was validated in vivo.
