A number of lysosomal enzymes are known to occur in multiple forms. Physical and kinetic properties such as thermolability, pH-optimum or electrophoretic mobility are used in differentiating or separating such isoenzymes. As these hydrolases, which have a low specifity, are responsible for the degradation of large macromolecules such as glycolipids, mucopolysaccharides and glycoproteins, the question may arise on the physiological meaning of multiple forms. In this study more details on the occurrence and on the molecular differences of these isoenzymes in human brain and liver are presented.
