II. Palmitic and stearic synthesis by an avocado supernatant system

The synthesis of palmitic and stearic acids by soluble proteins from avocado mesocarp has been examined. Evidence suggests that palmitate is made de novo and stearate by elongation of a C16 precursor. While the synthesis of palmitate from malonyl CoA is arsenite insensitive, the elongation reaction from palmitate to stearate is arsenite sensitive. The pattern of synthesis of the two acids is ne...

Inhibition of ileal water absorption by intraluminal fatty acids. Influence of chain length, hydroxylation, and conjugation of fatty acids.

The influence of fatty acids on ileal absorption of water, electrolytes, glucose, and taurocholate was examined in Thirty-Vella fistulas in five mongrel dogs. Fatty acid absorption also was measured. Segments of terminal ileum were perfused at steady state with isotonic electrolyte solutions containing 11.2 mM glucose, 4.5 mM taurocholate, and 0.1-5.0 mM fatty acid. Three C(18) fatty acids, ole...

Selective hydroxylation of highly branched fatty acids and their derivatives by CYP102A1 from Bacillus megaterium.

Highly branched fatty acids, the main components of the preen-gland waxes of the domestic goose and the Muscovy duck, and their derivatives are promising chiral precursors for the synthesis of macrolide antibiotics. The key step in the utilisation of these compounds is their regioselective hydroxylation, which cannot be achieved in a classical chemical approach. Three P450 monooxygenases, CYP10...
