The fractionation of cholesterol esters by silicic acid chromatography.
Within recent years, the technique of silicic acid chromatography to separate complex mixtures of lipides has been developed widely (1-3). At the present time it is possible to resolve some eight different classes of lipides ranging from hydrocarbons to phospholipides on a single column (4). In addition, this procedure has been used to separate classes of phospholipides from one another (5). Ou...
متن کاملCcxxv. Studies on Bacterial Phosphatases. I. the Decomposition of Phosphoric Acid Esters by Clostridium Acetobutylicum
THE conception of the phosphoric esterification of sugars as a necessary step in their metabolism in bacterial cells follows logically from considerations of carbohydrate breakdown in muscle and in yeast. But the experimental evidence in support of this conception in the case of bacteria is not very extensive, and information regarding the bacterial phosphatase systems which are responsible for...
متن کاملSeparation of tissue cholesterol esters and triglycerides by silicic acid chromatography.
bUnequivocal class separations of tissue lipids are important particularly whcn high temperature gas Chromatography is used at the same time for the determination of the long-chain acid composition of major lipid classes. This problem was studied most recently by Hirsch and Ahrens (1) ; their procedurc involves silicic acid column chromatography with clution by ether-petroleum ether mixtures fo...

متن کاملThe interaction of proteins with silicic acid.
Although silicon is a constituent of normal animal tissues, silicic acid formed by the dissolution of inhaled quartz particles can induce the formation of pathological lesions in which the normal tissue is replaced by fibrotic tissue arranged concentrically around the silica particles. The mechanism of the change which constitutes the disease, silicosis, is unknown. Schulman & Rideal (1937) dem...
