Gamma{0}}linolenic acid(GLA) yog ib qho tseem ceeb unsaturated fatty acid rau tib neeg lub cev, cov khoom siv rau ntau yam ntaub so ntswg biofilms, thiab ib tug precursor ntawm physiologically active tshuaj xws li prostaglandins, leukotrienes, thiab arachidonic acid.
Raws li ib txwm muaj lub cev muaj zog, gamma-linolenic acid yog muab los ntawm hepatic biotransformation ntawm linoleic acid.
Resource Development rau GLA
The biological resources of GLA mainly include plant resources and microbial resources. GLA in plant resources is mainly distributed in higher plants Willowaceae, Lithaceae, Scrophulariaceae, Saxifragaceae and so on. A typical resource rich in GLA is evening primrose, with a GLA content of 8 percent to 10 percent . In addition, black currant, microporous grass, borage, etc. are also rich in GLA, of which borage seeds have a GLA content of 21 percent to 25 percent . The microbial resources of GLA are mainly microalgae and fungi, including Mortierella, Rhizopus, Cunninghamella, etc., as well as Lanseria and Chlorella.
Kev siv GLA
Cov khoom ntawm GLA yog yav tsaus ntuj primrose roj. Nws cov tshuaj pharmacological tshwj xeeb tau ntxim nyiam los ntawm cov neeg kho mob hauv tsev thiab txawv teb chaws, thiab yog siv los ua cov khoom tseem ceeb ntawm hypoglycemic, hypolipidemic, tiv thaiv- mob, tiv thaiv- kev laus thiab qhov hnyav {{2} }poob tshuaj. Xyoo 1986, Tuam Tshoj yog thawj zaug hauv ntiaj teb siv tshuaj ntsiav tshuaj thaum yav tsaus ntuj los ua cov ntshav lipid - txo cov tshuaj.

Cov roj fatty acids ntawm yav tsaus ntuj primrose roj yog tsim los ntawm palmitic acid, stearic acid, oleic acid, linoleic acid thiab GLA. Cov ntsiab lus ntawmGamma Linolenic Acidfeem ntau yog qhov siab tshaj plaws thaum cov roj theem yog acidic.
