In vitro Effect of Lowering Surface Energy on Esterase Activity of Musca Homogenates

Naturevolume 199page1192 (1963) | Download Citation



THE primary reaction between an enzyme and a substrate or a poison is essentially an adsorption reaction involving the concentration of the substance in the enzyme/water interface. Homogenates are bio-colloids where the surface energy, particularly at interfaces, is a predominating form of energy on changes of which depend certain phenomena. In aqueous preparations of enzymes, substances which lower surface energy by concentrating at the enzyme/water interface may behave as barrier between enzyme and substrate, unless the latter has a higher affinity for interfaces.
