Conversion of Linoleic Acid Hydroperoxide to Hydroxy,
We have carried out a study of the reaction of 13Irydroperoxy-9-cis, 11-trans-octadecadienoic acid (linoleic acid hydroperoxide) with hematin. The major products are erythro-ll-hydroxy-l2,13-epoxy-S-octadecenoic acid, threo11-hydroxy12,13-epoxy-9-0~tadecenoic acid, 9,12,13-trihydroxy-lO-octadecenoic acid, 13-keto-9,ll-octadecadienoic acid, and 13-hydroxy-9,ll-octadecadienoic acid. Several minor...
متن کاملConjugated linoleic acid accumulation via 10-hydroxy-12-octadecaenoic acid during microaerobic transformation of linoleic acid by Lactobacillus acidophilus.
Specific isomers of conjugated linoleic acid (CLA), a fatty acid with potentially beneficial physiological and anticarcinogenic effects, were efficiently produced from linoleic acid by washed cells of Lactobacillus acidophilus AKU 1137 under microaerobic conditions, and the metabolic pathway of CLA production from linoleic acid is explained for the first time. The CLA isomers produced were iden...
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 کاملalpha-Glucosidase inhibitory activities of 10-hydroxy-8(E)-octadecenoic acid: an intermediate of bioconversion of oleic acid to 7,10-dihydroxy-8(E)-octadecenoic acid.
Microbial conversion of unsaturated fatty acids often leads to special changes in their product structures and in biological potential. In our continuous effort to screen natural products for their antimicrobial and enzyme inhibitor activities, we found that 10-hydroxy-8(E)-octadecenoic acid (HOD) exhibited strong anti-alpha-glucosidase (EC 3.2.1.20) activity. HOD is an intermediate in the bioc...
متن کاملEfficient Conversion of Phenylpyruvic Acid to Phenyllactic Acid by Using Whole Cells of Bacillus coagulans SDM
BACKGROUND Phenyllactic acid (PLA), a novel antimicrobial compound with broad and effective antimicrobial activity against both bacteria and fungi, can be produced by many microorganisms, especially lactic acid bacteria. However, the concentration and productivity of PLA have been low in previous studies. The enzymes responsible for conversion of phenylpyruvic acid (PPA) into PLA are equivocal....
