Contributing factors in the regulation of triglyceride deposition in and fatty acid release from bovine adipose tissue were investigated. Six Holstein steers were fasted for 9 days and then refed for 41 days. Blood samples from the jugular vein and adipose tissue samples from backfat biopsies were taken during fasting and refeeding periods. Concentrations of plasma free fatty aids, glycerol and...

The Fatty acid content and composition of fixed oil from Zanthoxylum rhetsa seeds was determined. The seeds were found to contain about ~19.5% of crude fixed oil on a dry weight basis. Fatty acids were converted into methyl esters and analyzed by GC-FID. Ten fatty acids were identified using GC-FID. The major monounsaturated and saturated fatty acids were oleic acid (41.6 43.5%) and palmitic ac...

Royal jelly (RJ) is generally regarded as the major reason of the significant morphological and functional differences between queen and worker bees. The unique and chemically most interesting feature of RJ is its fatty acids. RJ fatty acids are short-chained, 8-10 carbon free acids that are usually either hydroxy fatty acids or dicarboxylic acids. The major fatty acid in RJ is 10-hydroxy-2-dec...

Fatty acid synthesis (FAS), a primary metabolic pathway, is essential for survival of bacteria. Ralstonia solanacearum, a β-proteobacteria member, causes a bacterial wilt affecting more than 200 plant species, including many economically important plants. However, thus far, the fatty acid biosynthesis pathway of R. solanacearum has not been well studied. In this study, we characterized two form...

The metabolism of lipids in the ischemic liver has been examined in the attempt to define the cause of the previously described loss of phospholipid and to determine whether additional alterations occur that may be related to the disturbances in membrane function. With 3 hr of ischemia, 30% of the cellular phospholipid was lost when measured either as phosphate in a lipid extract of the whole l...

N-acylethanolamines (NAEs), such as anandamide (AEA), are a group of endogenous lipids derived from a fatty acid linked to ethanolamine and have a wide range of biological activities, including regulation of metabolism and food intake. We hypothesized that i) NAE plasma levels are associated with levels of total free fatty acids (FFAs) and their precursor fatty acid in fasting and non-fasting c...
