XXlll: Pyrolytic and Structural Investigations on the Polyphenol-amino Acid Pigments of Leaf Various hydrolytic procedures showed the presence of rutin, chlorogenic acid, and a series of amino acids; some information on the structure of these pigments is presented. The pyrolysis of the pigments was...
The proteolysis reaction converted proteins with a molecular mass <750 m/z to peptides and enhanced free-form amino acids. LC-MS-based metabolomics showed that leucine and glutamic acid contents were higher in the blood hydrolysate than other amino acids. Furthermore, in the proteolyzed whole ...
