Antioxidative Effect of Plasmalogens

The Structure of Plasmalogens

In the previous paper (1) we described a sequence of events which led from the isolation of crystalline “acetal phospholipide” by Feulgen and Bersin, and the realization by Schmidt and coworkers that the properties of this compound differed from those of native plasmalogen, to the preparation of plasmalogen fractions in this laboratory which indicated the presence of a fatty acid ester residue ...

The enzymatic synthesis of plasmalogens.

Recent work (1) has established that plaamalogenic phosphatides resemble the conventional glycerophosphatides such as phosphatidylcholme (I) very closely in structure, except that one fatty acid ester linkage is replaced in the plasmalogens by an aldehydogenic bond, presumably that of an a,fi-unsaturated ether. The exact position of the aldehydogenic bond is not yet certain. It had been conclud...

Antioxidative effect of ubiquinones on mitochondrial membranes.

Peroxidation of mitochondria occurs extensively in ubiquinone-depleted membranes. Reincorporation into the membranes of either the physiological ubiquinone or a short-chain homologue protects mitochondria against peroxidation. The ability to prevent this phenomenon is more evident in mitochondria that have incorporated ubiquinone-3 and might be ascribed to an ordering structural effect on the l...

effect of oral presentation on development of l2 learners grammar

this experimental study has been conducted to test the effect of oral presentation on the development of l2 learners grammar. but this oral presentation is not merely a deductive instruction of grammatical points, in this presentation two hypotheses of krashen (input and low filter hypotheses), stevicks viewpoints on grammar explanation and correction and widdowsons opinion on limited use of l1...
