Four fatty acid glycosides, designated A, B, C, and D, have been isolated from Ipomoea dichroa (family, Convolvulaceae).On chemical investigation, dichroside D was found to be a pentaglycoside of 11-hydroxyhexadecanoic acid, and the sugar chain is highly esterified with other fatty acids.The structure of the pentaglycoside has been established as 11-4)-O-(β-D-fucopyranosyl-(1->3))-O-α-L-rhamnopyranosyl-(1->4)-O-α-L-rhamnopyranosyl(1->2)-α-L-rhamnopyranosyl)oxy>hexadecanoic acid.

Two new compounds of acutacosides 1 and 2, pentasaccharide resin glycosides were isolated from the aerial parts of Argyreia acuta. The core of the two compounds was operculinic acid A, and they were esterfied at the same position, just one substituent group was linked at C-2 of Rha. The absolute configuration of the aglycone in the two compounds was established by Mosher's method, which was (11S)-hydroxyhexadecanoic acid (jalapinolic acid). Their structures were established by a combination of spectroscopic and chemical methods.
Products of cytochrome P450Biol (CYP107H1)-catalyzed oxidation of fatty acids

(Matrix presented) Oxidation of tetradecanoic and hexadecanoic acids by cytochrome P450Biol (CYP107H1) produces mainly the 11-, 12-, and 13-hydroxy C14 fatty acids and the 11- to 15-hydroxy C16 fatty acids, respectively. In contrast to previous reports, terminal hydroxylation is not observed. The enantiospecificity of fatty acid hydroxylation by P450Biol was also determined, and the enzyme was shown to be moderately selective for production of the (R)-alcohols.
