palmiticadj.

Brit.

/palˈmɪtɪk/,

/pɑːˈmɪtɪk/, U.S.

/pɑ(l)ˈmɪdɪk/

Origin: A borrowing from French. Etymon: French palmitique.

Etymology: < French palmitique (E. Frémy 1840, in Ann. der Chem. u. Pharm. 36 45), apparently < palme palm n.¹ + -it- , arbitrary element + -ique -ic suffix, although perhaps compare palmite pith of the palm tree (see palmite n.).The expected formation, French palmique , had already been coined in a different sense (see palmic adj.). N.E.D. (1904) gives only the pronunciation (pælmi·tik) /pælˈmɪtɪk/.

Chemistry.

palmitic acid n. a solid saturated fatty acid, CH₃(CH₂)₁₄COOH, found in palm oil and in many vegetable and animal fats.

1857 W. A. Miller Elements Chem. III. 394 Palmitic Acid..is obtained most readily from palm oil, the solid portion of which consists chiefly of the glycerin compound of palmitic acid.

1915 F. S. Hyde Solvents, Oils, Gums, Waxes 124 Wood grease..contains..esters of palmitic and myristic acids.

1971 Nature 30 July 327/2 Palmitic acid..is the most abundant saturated fatty acid in organisms.

1991 Lancet 19 Oct. 986/1 Myristic acid was the most atherogenic, with about four times the cholesterol-raising potential of palmitic acid.
