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 Ketinol Palmitate by Rat Liver*
Retinol acetate hydrolase is localized in rat liver microsomes whereas the retinol palmitate-hydrolyzing activity was found in the nuclear and in the mitochondrial lysosome-rich fractions. Acetone-dried powder from whole rat liver retained all of its retinol palmitate-hydrolyzing activity. Ammonium sulfate fractionation of the acetone-dried powder yielded a partially purified enzyme liberating ...

متن کاملApoptosis and Sphingomyelin Hydrolysis
Apoptosis, a form of cell death that is coordinated by a set of defined biochemical pathways, exists throughout the animal kingdom. Its critically important roles in development, homeostasis, and disease have made this a topic of intensive research and sometimes even more intensive controversy. One of these areas of controversy concerns the role of ceramide, produced by the hydrolysis of sphing...
متن کاملThe enzymic hydrolysis of carrageenin.
Carrageenin is the water soluble polysaccharide extractable from the red algae Chondrus crispus and Gigartina stellata. The polysaccharide is essentially a polymer of alpha-D-galactopyranoside-4-sulphate. Smith et al. (1954) fractionated carrageenin with potassium chloride into two components and obtained a precipitable component which could form gels and a nongelling component which remained i...
