The Stereospecific Conversion of Stearic Acid to Oleic Acid.
In several enzyme systems that catalyze the desaturation of stearic acid, oleic acid (cis-Ag-octadecenoic acid) is the sole product and the reaction is therefore characterized by positional and geometrical stereospecificity. We now have found that the desaturating system of Corynebacterium diphtheriae has the further property of selectively removing 1 particular hydrogen atom from each pair of ...
متن کاملConversion of oleic acid to linoleic acid.
Reports from this laboratory have described the formation of palmitoleic and oleic acids from their saturated counterparts by enzyme systems of yeast (2, 3). For introducing a double bond into the 9,lO position of the aliphatic chain, the desaturating enzymes, acting on the coenzyme A derivatives of the fatty acids, require reduced triphosphopyridine nucleotide, and molecular oxygen as hydrogen...
متن کاملa magnesium salt of stearic acid—a compound containing two stearic acids and one magnesium. In the body, stearic acid is primarily converted into oleic acid (a monounsaturated fatty acid). Oleic acid comprises the majority of olive
Both compounds have become more commonly used in dietary supplements. Stearic acid is commonly used as a binder in tablets, and it has lubricant properties. Magnesium stearate is a lubricant commonly used in tablet formulations. After achieving a homogenous blend of powdered ingredients, adding a small amount of magnesium stearate enables the powder blend particle surface to be sufficiently coa...
متن کاملMetabolic fate of oleic acid, palmitic acid and stearic acid in cultured hamster hepatocytes.
Unlike other saturated fatty acids, dietary stearic acid does not appear to raise plasma cholesterol. The reason for this remains to be established, although it appears that it must be related to inherent differences in the metabolism of the fatty acid. In the present study, we have looked at the metabolism of palmitic acid and stearic acid, in comparison with oleic acid, by cultured hamster he...
متن کاملFinal Report on the Safety Assessment of Oleic Acid, Laurie Acid, Palmitic Acid, Myristic Acid, and Stearic Acid
Oleic, Laurie, Palmitic, Myristic, and Stearic Acids are fatty acids with hydrocarbon chains ranging in length from 12 to 18 carbons with a terminal carboxyl group. These fatty acids are absorbed, digested, and transported in animals and humans. Little acute toxicity was observed when Oleic, Laurie, Palmitic, Myristic, or Stearic Acid or cosmetic formulations containing these fatty acids were g...
