  摘要：

  Diacylglycerophosphocholines containing (R)-3-, (R)-12-, (R)-17-hydroxy octadeca(e)noic acids and the corresponding racemates were synthesized and purified to homogeneity. The influence of the position of the hydroxy group on the monolayer packing properties of these fatty acids and their phosphatidylcholines was studied by Langmuir techniques and 1,2-di-[(R)-12-hydroxy-octadec-cis-9-enyl]-sn-glycero-3-phosphocholine displayed the largest lift-off area (330 Angstrom(2)/molecule). This result was in line with the thermotropic phase behavior of these phospholipids, as measured by differential scanning calorimetry (DSC): the gel-to liquid-crystalline phase transition temperature (T-m) passed through a minimum of -15.1 degrees C for 1,2-di-[(R)-12-hydroxy-octadec-cis-9-enyl]-sn-glycero-3-phosphocholine.

  [(17D)-17-3H1]stearate, and methyl [(17DL)-17-3H1]stearate have been prepared. Each of these compounds, mixed with methyl [U-14C]stearate, has been incubated with Torulopsis gropengiesseri, to give, after work-up, methyl 17-L-hydroxystearate and dimethyl octadecane-1,18-dioate. Determination of the 3H : 14C ratios of the latter compounds has established (a) that ω-hydroxylation and ω-1-hydroxylation of stearic acid

  Minquartynoic acid (1) was isolated as an antimalarial and antileishmanial constituent of the Peruvian tree Minquartia guianensis and its absolute configuration at C-17 established to be (+)-S through conversion to the known (+)-(S)-17-hydroxystearic acid (2) and confirmed using Mosher's method.

  The oil formed during fermentation by a strain of Torulopsismagnoliae consisted mainly of partly acetylated 2-O-β-D-glucopyranosyl-D-glucopyranose units attached β-glycosidically to 17-L-hydroxyoctadecanoic and 17-L-hydroxy-9-octadecenoic acids.
