... (PIn) for every phospholipid (PL) class and for the whole membrane was calculated. Total PL content was significantly lower in A. australe and N. korthausae , the two species with the highest MLSP, and a negative correlation between membrane total PIn and fish MLSP was found, meaning that the longer...

...J. M. Klaiman; E. R. Price; C. G. Guglielmo SUMMARY The fatty acid composition of muscle membrane phospholipids and fat stores may affect migration performance in birds. The purpose of this study was to investigate seasonal changes in the fatty acid composition of (1) pectoralis muscle...

...Jessica R. Nealon; Stephen J. Blanksby; Todd W. Mitchell; Paul L. Else SUMMARY The acyl composition of membrane phospholipids in kidney and brain of mammals of different body mass was examined. It was hypothesized that reduction in unsaturation index (number of double bonds per 100 acyl chains...

... to 15°C. To identify potential mechanisms by which oxidative capacities change, the modifications of phospholipid composition, membrane proteins and functional capacities of red muscle mitochondria were examined. Marked functional changes of isolated muscle mitochondria during warm acclimation...

..., no significant body-size-related variation was observed for either sodium pump concentration or molecular activity. Microsomal phospholipid fatty acid profile displayed little allometric variation in both the mammals and birds and was not correlated with molecular activity in either group. Brain phospholipids...

... gestation provided the first in vivo demonstration of matrotrophy of phospholipid for any viviparous teleost and of any nutrient for a member of the genus Sebastes . Radiolabel content increased as embryos progressed through ontogeny. Serum proteins of 170 kDa, present in vitellogenic and embryogenic...

... chromatography. The results indicate that gangliosides are completely absent from Cyanea capillata neurones, that the major sterol is not cholesterol, and that the five major phosphorus-containing lipids do not co-migrate with conventional phospholipid standards. The atypical lipid environment of Cyanea...
