Biosynthesis of iso-fatty acids in myxobacteria.
The fatty acid (FA) profiles of the myxobacteria Stigmatella aurantiaca and Myxococcus xanthus were investigated by acidic methanolysis of total cell extracts and GC or GC-MS analysis. The main components were 13-methyltetradecanoic acid (iso-15:0) and (Z)-hexadec-11-enoic acid (16:1, omega-5 cis). The biosynthesis of iso-FAs was investigated in several feeding experiments. Feeding of isovaleri...
متن کاملNetwork iso-elasticity and weighted α-fairness
Abstract: When a communication network’s capacity increases, it is natural to want the bandwidth allocated to increase to exploit this capacity. But, if the same relative capacity increase occurs at each network resource, it is also natural to want each user to see the same relative benefit, so the bandwidth allocated to each route should remain proportional. We will be interested in bandwidth ...
متن کاملClifford Beers
A great reformer has passed on. Clifford Whittingham Beers died on July 9th, 1943, at Providence, U.S.A., but his fine enthusiastic and farseeing spirit has left behind it work which persists and grows. At a time when such ideas as his were regarded as almost too progressive, and, in some quarters indeed, as subversive and revolutionary, he, a recovered patient, demonstrated the value of indivi...
متن کاملMetabolism of iso-bile acids in the rat.
Iso-bile acids, the BP-hydroxy epimers of the normally occurring bile acids, are commonly found in the feces of man and other animals but are not present in the bile. Since isochenodeoxycholic acid and isoursodeoxycholic acid were recently isolated from the feces of patients treated with chenodeoxycholic acid or ursodeoxycholic acid, the intestinal absorption and hepatic metabolism of [24-‘4C]i...
متن کاملA practical synthesis of long-chain iso-fatty acids (iso-C12–C19) and related natural products
A gram-scale synthesis of terminally-branched iso-fatty acids (iso-C12-C19) was developed commencing with methyl undec-10-enoate (methyl undecylenate) (for iso-C12-C14) or the C15 and C16 lactones pentadecanolide (for iso-C15-C17) and hexadecanolide (for iso-C18-C19). Central to the approaches outlined is the two-step construction of the terminal isopropyl group through addition of methylmagnes...
