Structural Properties and Anti-Inflammatory Activity of GLP-P, a Kefir-Derived Neutral Glycopeptide

Bioactive glycopeptides, commonly present in natural foods, exhibit notable immunomod- ulatory and neuroprotective effects. However, naturally occurring low-molecular-weight glycopeptides have rarely been reported, and their structural and functional properties remain insufficiently explored. In this study, a low-molecular-weight glycopeptide complex (GLP-P) was isolated from kefir. The structure of GLP-P was characterized via molecular weight (Mw) determination, monosaccharide and amino acid...
