Astaxanthin yog xim liab uas muab cov ntses salmon, cws thiab flamingos lawv cov xim liab. Nws cov qauv tshuaj zoo ib yam li beta-carotene (pom hauv cov carrots) thiab vitamin A. Astaxanthin yog ib feem ntawm pawg carotenoid. Astaxanthin yog tsim los ntawm ntau hom algae thiab plankton. Qee hom tsiaj hauv dej, suav nrog crustaceans nrog rau cw, noj cov algae thiab plankton thiab tom qab ntawd khaws cov xim hauv lawv cov plhaub, muab lawv cov xim liab. Cov ntses no, dhau los, tau noj los ntawm cov ntses (salmon, trout) thiab noog (flamingos, ibises), thiab khaws cov xim hauv lawv cov tawv nqaij thiab cov nqaij rog. Qhov no yog vim li cas ntses salmon thiab lwm yam tsiaj tshwm liab. Cov astaxanthin tsis yog tshuaj dawb, yog li cov tsiaj no khaws lawv cov xim liab.
Physiological teebmeem
Raws li cov txiaj ntsig zoo tshaj plaws ntawm ntuj antioxidant, astaxanthin lub luag haujlwm tseem ceeb yog txhawm rau tshem tawm cov dawb radicals thiab txhim kho lub cev tiv thaiv kev laus.
Nyob rau hauv tib neeg lub cev, cov dawb radicals yog generated thaum oxygen ua ke nrog complex metabolic molecules. Dawb radicals yog cov molecules tsis ruaj tsis khov uas tuaj yeem ua ke nrog txhua yam uas lawv tuaj yeem cuam tshuam nrog. Thaum lawv hnov mob, "oxidation" tshwm sim. Thaum cov txheej txheem oxidation pib, nws ua rau cov tshuaj tiv thaiv kab mob los tsim cov dawb radicals ntau dua.
Yog tias cov dawb radicals raug tso cai kom loj hlob dawb, peb lub cev yuav zoo li oxidized txiv apples. Oxidation tshwm sim thiab puas los ntawm cov dawb radicals sab hauv thiab sab nraud lub cev. Sab nraum lub cev, lawv tuaj yeem ua rau kev laus ntawm peb cov tawv nqaij - wrinkles, tawv nqaij qhuav - thiab txawm tias mob qog noj ntshav. Thaum peb muaj hnub nyoog, cov dawb radicals tuaj yeem ua rau lub zog thiab elasticity ntawm peb cov leeg.
Tsis tshua muaj zog penetrating zog
Ntuj astaxanthin tuaj yeem nkag mus rau peb qhov tseem ceeb ntawm tib neeg cov teeb meem ntawm ntshav-hlwb barrier, ntshav-pancreas barrier, thiab ntshav-testis barrier, thiab tsuas yog carotenoid uas tuaj yeem nkag mus rau hauv cov ntshav-hlwb barrier. Yog li, nws tsuas yog carotenoid nkaus xwb uas tuaj yeem ua rau lub hlwb hlwb thiab qhov muag retina.
Transmembrane stability
Lub cell membrane yog tsim los ntawm phospholipid bilayer. Ntuj astaxanthin tuaj yeem hla cov phospholipid bilayer ntawm cov cell membrane los tiv thaiv phospholipid molecules los ntawm kev puas tsuaj los ntawm oxidation, yog li ua kom muaj kev ruaj ntseg ntawm cov cell membrane thiab txuas ntxiv lub neej ntawm tes.
Super absorbency
Vim tias qhov hnyav molecular ntawm astaxanthin me me ntawm 596.8, txawm tias nrog cov ester pawg ntawm ob qho kawg, nws tsawg dua 1, 000 daltons. Nws tau yooj yim nqus los ntawm tib neeg lub cev thiab tuaj yeem ncav cuag ntau yam kabmob ntawm tib neeg lub cev.
Ntau cov kev tshawb fawb tau pom tias astaxanthin muaj qee yam kev txhim kho kev ua haujlwm ntawm ntau lub cev ntawm tib neeg lub cev. Piv txwv li, nws muaj kev kho mob zoo heev rau cov kab mob ntawm tib neeg lub paj hlwb thiab cov hlab plawv thiab cerebrovascular systems; nws tuaj yeem ncua thiab tiv thaiv kev laus ntawm daim tawv nqaij; nws tuaj yeem txo oxidative kev puas tsuaj rau pob qij txha, txhim kho cov leeg mob, thiab rov qab sai sai los ntawm kev ua kom qaug zog; nws tuaj yeem tiv thaiv qog nqaij hlav. , muaj kev cuam tshuam ncaj qha rau kev loj hlob ntawm cov qog nqaij hlav cancer, thiab lwm yam.
Qhov muag thiab central paj hlwb tiv thaiv
Astaxanthin tuaj yeem dhau los ntawm cov hlab ntsha-hlwb thaiv, tiv thaiv cov retinal oxidation thiab kev puas tsuaj rau cov cell photoreceptor, qhia tias astaxanthin muaj txiaj ntsig zoo hauv kev tiv thaiv thiab kho "muaj hnub nyoog ntsig txog macular degeneration" thiab txhim kho retinal muaj nuj nqi; astaxanthin muaj kev tiv thaiv Lub peev xwm ntawm lub hauv paus paj hlwb, tshwj xeeb tshaj yog lub paj hlwb thiab txha nraub qaum, tuaj yeem kho lub hauv paus paj hlwb raug mob xws li ischemic repetitive perfusion raug mob, txha caj qaum raug mob, Parkinson's syndrome, Alzheimer's syndrome, thiab lwm yam.
Tiv thaiv UV hluav taws xob
Kev ua haujlwm antioxidant muaj zog ntawm astaxanthin tuaj yeem siv los ua lub peev xwm photoprotectant los tiv thaiv kev yees duab ntawm daim tawv nqaij. Astaxanthin tuaj yeem tshem tawm cov dawb radicals uas ua rau cov tawv nqaij laus los ntawm lub computer hluav taws xob, ib puag ncig muaj kuab paug, thiab haus luam yeeb, ncua kev laus ntawm daim tawv nqaij, tiv thaiv cell membranes thiab mitochondrial membranes los ntawm oxidative puas, yog li tiv thaiv cov hlwb los ntawm kev puas tsuaj los ntawm oxidative tshua.
suppress qog
Astaxanthin tuaj yeem cuam tshuam qhov pib carcinogenesis tshwm sim los ntawm cov tshuaj lom neeg, thiab muaj kev tiv thaiv kev loj hlob thiab ntxiv dag zog rau lub cev tiv thaiv kab mob ntawm cov cell epithelial uas raug rau cov carcinogens, xws li inhibiting kev loj hlob ntawm qog nqaij hlav qog nqaij hlav, qog nqaij hlav hauv qhov ncauj, mob qog noj ntshav, mob qog noj ntshav thiab mob qog noj ntshav. . Astaxanthin tseem tuaj yeem txo cov carcinogenicity ntawm aflatoxin thiab muaj cov txiaj ntsig zoo ntawm kev txo tus naj npawb thiab ntim ntawm daim siab qog hlwb raug ntxias los ntawm aflatoxin.
Anti-inflammatory zog: Astaxanthin lub zog antioxidant zog tuaj yeem pab inhibit dawb radicals thiab txo oxidative puas rau pob qij txha.
Tshem tawm kev qaug zog
Astaxanthin tuaj yeem ua rau cov leeg nqaij muaj zog thiab ua kom cov leeg mob, rov qab los ntawm kev tawm dag zog sai, thiab txo qis qhov pib mob nqaij (DOMs) tom qab kev tawm dag zog.
Tiv thaiv kab mob plawv thiab cerebrovascular
Astaxanthin muaj cov txiaj ntsig ntawm kev nce qib siab lipoprotein (HDL) thiab txo LDL hauv lub cev. Astaxanthin tuaj yeem txo cov oxidation ntawm apolipoproteins thiab tuaj yeem siv los ua kev npaj los tiv thaiv arteriosclerosis, kab mob plawv thiab ischemic puas hlwb.
