(20) The results confirmed the earlier postulated differential utilization of palmitic and stearic acids in glycerolipid biosynthesis as well as supported the hypothesis of a precursor-product relationship between the oligoenoic and tetranoic species of both phosphatides.
Stearin
Definition:
(n.) One of the constituents of animal fats and also of some vegetable fats, as the butter of cacao. It is especially characterized by its solidity, so that when present in considerable quantity it materially increases the hardness, or raises the melting point, of the fat, as in mutton tallow. Chemically, it is a compound of glyceryl with three molecules of stearic acid, and hence is technically called tristearin, or glyceryl tristearate.
Example Sentences:
(1) The dietary fats were corn oil, soybean oil, palm oil, palm olein and palm stearin.
(2) The overheating of animals was accompanied by a decrease in unsaturation of lipids in liver tissue, brain and skeletal muscles due to a decrease in amounts of arachidonic acid and to an increase in content of palmitinic and stearinic acids.
(3) Palmitine and stearine, as well as oleic and linoleic acid concentrations were significantly lower 12 hours postoperatively in group I than groups II and III (P < 0.05).
