-galactosidases belong to glycosyl hydrolase family of enzymes.These enzymes are widely distributed in nature. -galactosidases have been implicated in many biological functions like hydrolysis of dietary lactose,degradation of glycolipids and proteoglycans,fruit ripening, cell elongation, storage mobilisation and petal senescence. - galactosidase has proven as a best alternative for elimination of lactose intolerance.The present study was aimed at investigating the biochemical properties of -galactosidases from apricots.Three isoenzymes( gal I, gal II and gal III) were obtained by salt...
