Popis: Inhibitory activities of proteins originated from plants and animals were estima ted for lipase. All proteins tested inhibited Rhizopus delemar and Candida cylindracea l ipases, but they did not inhibit porcine pancreatic lipase much in contrast. Homo-poly-amino acids were employed to simplify the reaction system and consequently make clear the me chanism of the lipase inhibition by proteins. Simplified interfacial studies were also p erformed to explain the inhibitory mechanism. The hydrophobicity and the conformational stru cture of each protein were concerned with the inhibitory activity. It is probable that th e protein inhibits the lipase activity by the physical separation of lipase from its subst rate.
