Alkyl-branched fatty compounds are of interest for industrial products in the cosmetics and lubricant areas. In this review, clayand zeolite-catalyzed isomerizations of unsaturated fatty compounds, especially of oleic acid, are discussed. While clay-catalyzed reactions give most complex mixtures of dimeric fatty acids and of monomeric so-called “isostearic acid”, the zeolite-catalyzed process y...

We have examined the fatty acid composition of the mitochondrial membranes in three strains of Tetrahymena pyriformis. All three had similar components and exhibited large amounts of unsaturated fatty acids. The cytoplasmic mutant, CA-10, which has a slower growth rate and unusual membrane morphology, had a slightly higher amount of iso-acids but was otherwise similar to the other strains in fa...

Specific high-affinity binding sites for non-steroidal anti-oestrogens such as tamoxifen have been identified in many animal and human tissues. The function of these binding sites and the nature of their endogenous ligands are currently unknown. Our laboratory has previously reported that unsaturated fatty acids at micromolar concentrations inhibited [3H]tamoxifen binding to the anti-oestrogen-...

An increase in apparent thyroxine values obtained by competitive protein-binding assay on storage of sera is well documented. We find that the major source of this positive bias is probably the unsaturated nonesterified fatty acids. Nonesterified fatty acids cause a positive basis in the competitive protein-binding assay for serum thyroxine because they inhibit the binding of radioactive thyrox...

opium poppy (papaver somniferum l.) has two major products: alkaloids in the capsules and the seeds.  the seed contains oil, protein, carbohydrate, moisture and mineral matters. the seed oil is rich in unsaturated fatty acids, particularly linoleic and oleic acid. remaining meals after oil extraction are the important source for animal diets. the united nations recognize turkey and india as tra...

Background: The effects of dietary fats on the risk of coronary artery disease (CAD) have traditionally been estimated from their effects on LDL cholesterol. Fats, however, also affect HDL cholesterol, and the ratio of total to HDL cholesterol is a more specific marker of CAD than is LDL cholesterol. Objective: The objective was to evaluate the effects of individual fatty acids on the ratis of ...

The work on liver lecithins by Levene and Ingvaldsen’ and by Levene and Simms,z has shown the existence of lecithins which are distinguished from one another by the nature of their unsaturated fatty acids. There were isolated from liver lecithin, two unsaturated fatty acids, oleic and arachidonic, as well as two saturated acids, palmitic and stearic. Hence on the basis of the present findings i...

As has been shown in previous researches the fatty acids in human blood exist, as glycerides, cholesterol esters, soaps, or as free acids; they are also represented as a radical of lecithin and the phosphatide groups. Their content varies in continued starvation, fat absorption, anesthesia, certain pathological conditions, et’c., as recently reported and confirmed in a series of papers by B1oor...
