ASTAXANTHIN NTUJ
Kev Taw Qhia
Astaxanthin ntuj yog ib hom carotenoid uas muaj cov tshuaj antioxidant muaj zog, uas muaj cov teebmeem ntawm antioxidant, tiv thaiv kev laus, tiv thaiv qog thiab tiv thaiv cov kab mob plawv thiab cov hlab ntsha hauv lub hlwb. Nws tau siv thoob ntiaj teb hauv cov khoom noj khoom haus kev noj qab haus huv, cov tshuaj pleev ib ce zoo, cov tshuaj thiab lwm yam teb. Astaxanthin nws tus kheej tsis ruaj khov heev, yooj yim rau oxidize, yooj yim rau decompose hauv lub teeb, thiab feem ntau ntawm lawv khaws lawv cov haujlwm hauv daim ntawv ntawm astaxanthin gel ntawm kev ua lag luam.
Cov khoom siv tshuaj lom neeg
Lub npe tshuaj ntawm astaxanthin yog 3,3'-dihydroxy-4,4'-diketone-β,β'-carotene, cov mis molecular yog C40H52O4, cov astaxanthin crystalline yog xim liab, lub ntsiab lus yaj yog 215-216 ℃, insoluble hauv dej, rog-soluble, thiab yooj yim soluble hauv feem ntau cov kuab tshuaj organic xws li chloroform, acetone thiab benzene. Cov saw hlau sib txuas hauv cov qauv molecular ntawm astaxanthin, nrog rau cov ketone unsaturated thiab hydroxyl pawg ntawm qhov kawg ntawm cov saw hlau sib txuas ob chav, tuaj yeem nyiam cov electrons unpaired ntawm cov radicals dawb lossis muab cov electrons rau cov radicals dawb, yog li tshem tawm cov radicals dawb thiab ua rau muaj cov teebmeem antioxidant.
SIV
Siv cov tshuaj antioxidant thiab cov teebmeem txhawb kev tiv thaiv kab mob ntawm astaxanthin, nws tuaj yeem ua rau hauv tshuaj los tiv thaiv kev puas tsuaj ntawm cov ntaub so ntswg oxidative. Cov kev tshawb fawb qhia tau tias astaxanthin tuaj yeem tiv thaiv lub peev xwm ntawm lub paj hlwb, tshwj xeeb tshaj yog lub hlwb thiab tus txha nqaj qaum, los ntawm cov ntshav-lub hlwb thaiv, thiab tuaj yeem kho cov kev raug mob ntawm lub paj hlwb hauv nruab nrab xws li ischaemic rov ua dua perfusion raug mob, tus txha nqaj qaum raug mob, Parkinson's syndrome thiab Alzheimer's syndrome; zoo tiv thaiv retinal Oxidation thiab kev puas tsuaj rau cov hlwb photosensitive muaj cov txiaj ntsig zoo rau kev txhim kho kev ua haujlwm ntawm retinal.
