Abstract
Soluble proteins from a red wine were separated on Sephadex G-75 Superfine in two fractions of high (void volume Kav 0) and low (Kav 0.8) apparent molecular weights. The high MW component may be part of a covalent protein-polysaccharide complex as indicated by its particular richness in serine and threonine and the presence of hydroxyproline.
