Low density lipoprotein-activated lysolecithin acylation by human plasma lecithin-cholesterol acyltransferase. Identity of lysolecithin acyltransferase and lecithin-cholesterol acyltransferase.
There is in normal plasma an enzyme activity which converts labeled lysolecithin to lecithin by an energy-independent low density lipoprotein-activated pathway. Studies were undertaken to compare the identity of this enzyme with lecithin-cholesterol acyltransferase. During purification of the enzyme by ultracentrifugation and by chromatography on high density lipoprotein affinity column, DEAE-S...
متن کاملLysolecithin metabolism by human platelets.
Human platelets incubated with 32p lysolecithin convert this compound to platelet lecithin and the water-soluble product glycerylphosphorylcholine. Lecithin synthesis from lysolecithin by intact platelets has a pH optimum of 9, whereas platelet homogenates show a pH optimum of 7.5 for the same reaction. Conversion of lysolecithin to platelet lecithin takes place by direct acylation of lysolecit...
متن کاملMechanism of bactericidal activity of lysolecithin and its biological implication.
Lysolecithin exhibited bactericidal effect on mycobacteria and staphylococci, but not on E. coli. The effect on staphylococci was manifested shortly after exposure, but that on mycobacteria was of the delayed type. The mycobactericidal activity was dependent on the fatty acid moiety of the chemical structure reflecting the cytotoxicity of the free form. The activity on staphylococci was not, ho...
متن کاملLysolecithin and Hemolytic Anemia. the Significance of Lysolecithin Production in the Differentiation of Circulating and Stagnant Blood.
Considerations regarding the etiology of hemolytic jaundice are inextricably bound up with the presence of spherocytosis and the associated increase in hypotonic saline fragility, and the effect of splenectomy in the amelioration of this disorder. Although many different opinions are advanced regarding the etiology of the disease, the outstanding ones are those postulating a faulty bone marrow ...
