Linoleyl alcohol

Linoleic acid is probably the best substrate for assay. It is readily dispersed at alkaline pH, and at acid or neutral pH it is no more difficult to suspend than the methyl ester or the glyceride. Although some species of lipoxygenase show more favorable action with esters than others, we know of no instance where such enzymes do not also act well on linoleic acid. The poor water solubility of linoleic acid and its changing dissociation in the pH range of interest are a disadvantage and usually require emulsifiers. The sulfate ester of linoleyl alcohol, which does not possess this disadvantage, has been proposed by Allen (108) and appears to be a welcome improvement. [Pg.333]

Oleyl alcohol has been prepared by the action of sodium and absolute alcohol on ethyl oleate, by the action of sodium and absolute butyl alcohol on butyl oleate, and by the action of sodium and absolute ler/.-butyl alcohol on ethyl oleate. This procedure is essentially that of Kass and Burr, who prepared linoleyl alcohol. The purification step was derived from the low-temperature crystallization technique of Hartsuch. ... [Pg.82]

Palmitic and myristic acids (Applied Science Laboratories, State College, Pa.) and oleic acid (Hormel Institute, Austin, Minn.) were applied to the Langmuir trough in a hexane solution. Constant pressure-variable area measurements were obtained at 25 °C with a floating barrier and piston oils as previously described (23). Castor oil, tri-m-tolylphos-phate, and linoleyl alcohol (Hormel Institute, Austin, Minn.) were the piston oils they exerted surface pressures of 17 0.7, 9.5, and 33.5 dynes/cm. Variable pressure-variable area measurements were obtained at 24°-26°C with a movable barrier propelled by a high-torque motor (27). tr was measured by the Wilhelmy plate technique (27). [Pg.56]

The polyunsaturated fatty acids, which were first recognized by Burr and Burr (1930) as possessing biopotency in curing or preventing the fat-deficiency disease produced by the rigid exclusion of fat from the diet, were linoleic add, 9,12-octadecadienoic acid, linohnic add, 9,12,15-octadecatrienoic acid, and arachidonic add, 5,8,11,14-eicosatetraenoic acid. Hume et al. (1938) reported that a docosahexaenoic acid of unknown structure possesses-similar biological activity. Moreover, methyl linoleate and linoleyl alcohol, 9,12-octadecadienol, were found by Turpeinen (1937, 1938) to possess biopotency, presumably because they are converted to arachidonic acid in the body in the course of their intermediary metabolism. [Pg.31]

Linoleic acid is used in making soaps, emulsifiers, and quick-drying oils. Reduction of linoleic acid yields linoleyl alcohol. Linoleic acid has become increasingly popular in the beauty products industry because of its beneficial properties on the skin. Research points to linoleic acid s anti-inflammatory, acne reductive, and moisture retentive properties when applied topically on the skin. [Pg.32]

Methyl linoleate and methyl linolenate are isomerized to conjugated isomers with potassium t-butoxide at 60 °C and with tris(triphenylphosphine)-chlororhodium at 65 °C. Linoleyl alcohol and its methyl ether react with butyl-lithium and carbon dioxide to give mainly the 9-carboxy-Ai - and 13-carboxy-A -derivatives ... [Pg.190]
