Enzymic hydrolysis of glycolipids and phospholipids

Phosphoinositides. 3. Enzymic hydrolysis of inositol-containing phospholipids.

The 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...

Molecular volumes of phospholipids and glycolipids in membranes.

Data on the molecular volumes of phospholipids and glycolipids in membranes are collected together in order to determine the contributions from the component groups, for as wide a range of lipids as possible, including sphingolipids. Wherever possible, the volumes of the methylene groups in the lipid chains are established from the dependence on chain length at fixed temperature in a given phas...

The Enzymic Hydrolysis of p - Glucosides

The present work arose out of an attempt to understand the course of cellulose breakdown in preparations of cellulolytic enzymes which also contained cellobiase activity. Previous investigations of the ,B-glucosidases have been of three kinds-an examination of their specificity ranges (reviewed by Veibel, 1950), the demonstration of their reversibility and the study of glucosyl transfer. Croft-...

Human platelet cytoskeletons: specific content of glycolipids and phospholipids.

The lipid composition of platelet cytoskeletons was analyzed. Triton X-100 (0.5%) was used to prepare cytoskeletons from thrombin-treated platelets. The lipid/protein ratio of platelet cytoskeletons was 0.260 and the phospholipid/protein ratio was 0.177, which were comparable to the ratios present in platelets. However, there was a selective enrichment of platelet lipids in platelet cytoskeleto...
