DOCUMENT TYPE: Patent CA Section: 17 (Food and Feed Chemistry) Linear polyglycerols with a narrow mol. wt. distribution, that are low in odor and color, and in which hydroxyl groups are mostly secondary or tertiary are prepd. When esterified with fatty acids, e.g. from olive oil, a compn. useful as a low-calorie fat substitute is produced. The polyglycerol is prepd. by heating a precursor (e.g. glycerin) while the temp. is maintained at 100-160°. The monomer is added at a rate that avoids buildup of unreacted monomer. Prior to esterification, the polyglcerol may be reacted with an alkylene oxide. Propoxylated decaglycerol fatty acyl esters prepd. as described were not a substrate for lipase. Rats maintained on a diet contg. this oil passed 62-73% of the oil into the feces. .

Cyclic fatty esters: synthesis, characterization, and lipolysis of isomeric triglycerides of 9-(6-propyl-3-cyclohexenyl)-(Z)-8-nonenoic acid

Cyclic fatty esters: synthesis, characterization, and lipolysis of isomeric triglycerides of 9-(6-propyl-3-cyclohexenyl)-(Z)-8-nonenoic acid. Awl, R. A.; Frankel, E. N.; Brooks, D. D.; Weisleder, D. (Agric. Res. Serv., U.S. Dep. Agric., Peoria, IL 61604, USA). Chem. Phys. Lipids, 41(1), 65-80 (English) 1986. CODEN: CPLIA4. ISSN: 0009-3084. DOCUMENT TYPE: Journal CA Section: 26 (Biomolecules and Their Synthetic Analogs) Section cross-reference(s): 7 Triglycerides of a model cyclic fatty acid (Cy) (I) were synthesized for biol. and toxicity evaluations. The triglyceride II (CyCyCy) was transesterified with triolein (OOO) to obtain mixts. of triglycerides: III (OOCy), IV (OCyO), V (OCyCy), and VI (CyOCy), which were sepd. by preparative HPLC into 2 pairs of isomeric triglycerides. The mixed triglycerides III-VI were synthesized sep. and a 13C-NMR method was developed to est. ratios.In this experiment, several chemicals are used like 108056-17-3 and 112-77-6 Triglycerides II-VI were characterized spectrally, and their relative rates of hydrolysis by lipase were compared. Although II was completely resistant to lipolysis, III and VI hydrolyzed significantly slower than OOO, and IV and V hydrolyzed as readily as OOO. Therefore, partial Cy triglycerides formed in heat-abused fats can undergo lipolysis and likely be absorbed like normal dietary fats. .
