Spin Label Motion in Fatty Acids

Spin-label Order Parameter Calibrations for Slow Motion

Calibrations are given to extract orientation order parameters from pseudo-powder electron paramagnetic resonance line shapes of 14N-nitroxide spin labels undergoing slow rotational diffusion. The nitroxide z-axis is assumed parallel to the long molecular axis. Stochastic-Liouville simulations of slow-motion 9.4-GHz spectra for molecular ordering with a Maier-Saupe orientation potential reveal ...

Determination of Tocopherols and Fatty Acids in Seeds of

  Background: The dried fruits of Silybum marianum (L.) Gaertn (Compositae) contain silymarin, an isomeric mixture of flavonolignans. Silymarin acts as a strong anti -hepatotoxic. This fruits contains a high amount of oil .  Objective: The objective of this study was to determine total lipid content, fatty acid composition and content of different kind of tocopherols in seed oils of S. marianum...

Metabolic Effects of Polyunsaturated Fatty Acids in Chickens: A Review

Chicken has been used as a suitable model for lipid metabolism studies, because dietary modifications especially dietary fat type can change chicken body composition. Fats act as a condense source of energy and certain fatty acids such as polyunsaturated fatty acids (PUFAs) are required for both animal and human health. The n-3 PUFAs, especially, eicosapentaenoic acid (EPA) and docosahexaenoic ...

Fatty Acids in Dermatology

Fatty Acids in Serum

The relative amounts of unsaturated fatty acids in the serum lipids of 14 patients who have undergone small bowel resection have been investigated. These results are compared with those from control subjects and also from patients suffering from cancer of the oesophagus. Both groups of patients showed patterns of unsaturated fatty acids suggesting essential fatty acid deficiency. In the resecti...
