Oleic acids tsim ib chav kawm ntawm unsaturated fatty acids los yog lawv cov derivatives, cov neeg sawv cev tshaj plaws uas yog oleic acid (C₁₈H₃₄O₂). Cov khoom hauv chav kawm no feem ntau muaj ib lossis ntau dua cov pa roj carbon -carbon ob daim ntawv cog lus, cov yam ntxwv uas ua rau lawv feem ntau muaj nyob hauv cov roj ua kua hauv chav tsev kub. Lawv tau dav dav hauv cov roj cog thiab tsiaj rog- xws li cov roj txiv roj, roj rapeseed, thiab nqaij nyug siab- thiab ua cov khoom tseem ceeb ntawm cov fatty acids uas tshwm sim.
Oleic acids yog cais raws li monounsaturated fatty acids, uas yog muaj nyob rau ntawm ib tug acidic carboxyl pawg (–COOH) thiab ib tug unsaturated hydrocarbon saw (–CH=CH–). Cov qauv molecular tshwj xeeb no ua rau lawv tuaj yeem koom nrog ntau yam tshuaj lom neeg cov tshuaj tiv thaiv- xws li esterification thiab saponification-thaum tseem ua rau lawv muaj qee yam kev ua haujlwm ntawm lub cev. Oleic acids nkag siab nrog cov hauv paus tsim cov xab npum; Tsis tas li ntawd, lawv tuaj yeem dhau los ntawm hydrogenation lossis oxidation cov tshuaj tiv thaiv rau cov txiaj ntsig derivatives nrog cov khoom sib txawv, xws li stearic acid thiab oleic acid esters.
Oleic acids pom ntau daim ntawv thov thoob plaws hauv kev lag luam, zaub mov, thiab kev lag luam tshuaj. Hauv kev lag luam khoom noj khoom haus, oleic acid ua haujlwm tseem ceeb ntawm cov roj cog, ua lub luag haujlwm tseem ceeb hauv cov khoom noj muaj txiaj ntsig thiab palatability. Hauv kev lag luam tshuaj thiab cov neeg siv khoom lag luam, nws yog siv hauv kev tsim cov xab npum, emulsifiers, lubricants, thiab surfactants. Hauv kev kho mob thiab kev kho mob, oleic acid kuj tau lees paub rau nws cov peev xwm los tiv thaiv - mob thiab mob plawv. Muab lawv cov keeb kwm ntuj tsim thiab muaj peev xwm ua tau zoo, oleic acids tau tsim lawv tus kheej ua cov ntaub ntawv tseem ceeb hauv kev lag luam tshuaj.
