Tam sim no, lub ntsiab tseem ceeb tshaj plaws astaxanthin hmoov nyob rau hauv kev ua lag luam yog muab rho tawm los ntawm Haematococcus Pluvialis, uas accumulates astaxanthin nyob rau hauv lipid vesicles nyob rau hauv cov zaub mov tsis txaus thiab hnyav ib puag ncig. Vim Haematococcus Pluvialis nyiam loj hlob nyob rau hauv cov chaw uas muaj hnub ci zog, astaxanthin tuaj yeem tiv thaiv lub cell nucleus los ntawm kev puas tsuaj ntawm cov dawb radicals uas tsim los ntawm ultraviolet hluav taws xob. Ntuj astaxanthin muaj cov qauv molecular tshwj xeeb, ua rau nws ntau pua lub sij hawm muaj zog dua li lwm cov tshuaj antioxidant molecule.
Carotenoids yog cov ntsiab lus dav dav rau chav kawm ntawm cov xim ntuj uas muaj cov qauv polyisoprene. Lawv feem ntau pom nyob rau hauv cov tsiaj, cov nroj tsuag siab dua, fungi thiab algae. Thiab lawv yog qhov tseem ceeb ntawm cov vitamin A tau los ntawm tib neeg lub cev, thiab muaj cov haujlwm ntawm kev tiv thaiv oxidant, tiv thaiv kab mob, thiab tiv thaiv kab mob plawv, tiv thaiv qhov muag, thiab lwm yam.
Astaxanthin yog carotenoid thiab qib siab tshaj plaws ntawm carotenoid synthesis. Nws muaj xim liab dawb thiab cov qauv tshuaj zoo ib yam li β-carotene. Beta-carotene, lutein, canthaxanthin, lycopene, thiab lwm yam yog tag nrho cov khoom nruab nrab ntawm carotenoid synthesis, yog li nyob rau hauv qhov xwm txheej, astaxanthin muaj zog antioxidant zog. Nws yog dav pom nyob rau hauv lub ntiaj teb lom, tshwj xeeb tshaj yog nyob rau hauv cws, crab, ntses, algae, poov xab thiab noog plaub. Nws yog ib qho ntawm cov carotenoids tseem ceeb hauv cov kab mob marine.
Kev ua haujlwm antioxidant ntawm ntuj astaxanthin tshaj tag nrho cov antioxidants uas twb muaj lawm. Nws muaj peev xwm tshem tawm cov dawb radicals yog 6000 npaug ntawm cov vitamin C; 1000 npaug ntawm vitamin E; 800 npaug ntawm coenzyme Q10; 1800 zaug ntawm nitric oxide; 3100 npaug ntawm nato; 700 npaug ntawm anthocyanins;β- 100 npaug ntawm carotene; 10 npaug ntawm Lycopene; 200 npaug ntawm Lutein; 320 npaug ntawm tshuaj yej polyphenols; Tsis tas li ntawd, tsuas yog algae, poov xab thiab kab mob tuaj yeem tsim cov astaxanthin, thiab cov tsiaj siab dua tsis tuaj yeem hloov cov qauv tshuaj no. Ntuj astaxanthin kuj muaj qhov pom tseeb, nws tsuas yog carotenoid uas tuaj yeem dhau los ntawm cov hlab ntsha-hlwb barrier. Yog li ntawd, astaxanthin yog qhov tsim nyog los ua tus huab tais ntawm carotenoids.
