Enzymic hydrolysis of sphingomyelin in the presence of bile salts.
Sphingomyelin in mixed dispersion with bile salts was hydrolysed by the solubilized sphingomyelinase of rat brain lysosomes. In parallel studies, physical properties of these dispersions were determined. The kinetic curves that described the rate of hydrolysis as a function of increasing concentrations of bile salt were multiphasic. A region of very low activity was followed by an ascending por...
متن کاملHydrolysis of milk fat globules by pancreatic lipase. Role of colipase, phospholipase A2, and bile salts.
Human milk fat globules require colipase to be hydrolyzed by pancreatic lipase in the presence of bile salts. This is contrary to a recent report in this Journal (J. Clin. Invest. 67: 1748-1752.) according to which inhibition of lipase by bile salt could be overcome by the addition of colipase or phospholipase A2. This latter finding is shown to be due to contamination of commercially available...
متن کاملEffects of Condition Enzymatic Hydrolysis on Degrees of Hydrolysis and Antioxidant Activity of Head Protein of Bighead (Aristichthys nobilis)
Background and Objectives: Enzymatic hydrolysis is an effective practical technology that recovers valuable proteins from far-less farmed fish without losing their nutritional characteristics. Enzymatic hydrolysis of protein sources such as aquatic animals is a type of protein recycling. In the present study, effects of temperature, time and concentration of papain enzyme on hydrolysis degree a...
متن کاملAdsorption of 1,1-Dimethylhydrazine by Hydrolysis Lignin
Many modern launch vehicles use unsymmetrical dimethylhydrazine (UDMH) as liquid fuel in the space program. UDMH is highly toxic and poses a serious threat to the environment and to humans. One of the most effective methods of UDMH neutralization in case of fuel spills is adsorption. This paper is the first to suggest using hydrolysis lignin as rocket fuel adsorbent. The research was based ...
متن کاملHydrolysis of human milk fat globules by pancreatic lipase: role of colipase, phospholipase A2, and bile salts.
Human milk fat globules were used to explore how dietary triglycerides are hydrolyzed by pancreatic lipase. These triglycerides were hydrolyzed very slowly by lipase alone as if the surface layer of proteins and phospholipids impeded the action of the enzyme. The inhibition of lipase activity could be overcome by addition either of colipase or of pancreatic phospholipase A2. Colipase enhanced t...
