Dab tsi yog astaxanthin?
Astaxanthin (Lus Askiv: Astaxanthin, tseem hu ua metaphycoxanthin lossis astaxanthin) yog hom carotenoid thiab muaj zog ntuj antioxidant. Zoo li lwm cov carotenoids, astaxanthin yog cov roj-soluble thiab dej-soluble pigment uas tuaj yeem pom hauv cov kab mob hauv hiav txwv xws li cws, crabs, salmon, thiab algae.
Muaj nuj nqi
1. Txhim kho tib neeg kev tiv thaiv
Nrog rau lub hnub nyoog nce thiab nce siab ntawm kev ciaj sia, tshwj xeeb tshaj yog kev hloov pauv ntawm qhov chaw nyob thiab ib puag ncig kev sib raug zoo, lub peev xwm ntawm cov neeg feem coob los tsim cov dawb radical scavengers hauv lub cev maj mam txo qis, ua rau poob ntawm scavengers hauv lub cev. Raws li cov ntsiab lus txo qis, qhov kev ua si maj mam txo qis, yog li ua rau lub cev tsis muaj zog tiv thaiv kev puas tsuaj dawb radical, ua rau lub cev laus thiab muaj cov kab mob pathologies.
Dawb radicals ua rau lub cev tiv thaiv kab mob los yog ua rau cov lymphocytes puas, uas tuaj yeem ua rau lub cev cellular thiab humoral lub cev tsis muaj zog, txo qis kev tiv thaiv kab mob thiab ua rau cov kab mob autoimmune.
Txhawm rau tiv thaiv kev puas tsuaj dawb radical, ntxiv cov dawb radical scavengers tuaj yeem ntxiv rau lub cev muaj sia kom ua tiav lub hom phiaj ntawm kev tiv thaiv kab mob thiab ncua kev laus. Raws li lub ntiaj teb muaj zog tshaj plaws antioxidant, astaxanthin tau dhau los ua tib neeg xaiv thawj. Nws tuaj yeem tiv thaiv cell oxidation, tshem tawm cov dawb radicals hauv lub cev, txhim kho tib neeg kev tiv thaiv, thiab tiv thaiv tib neeg lub cev los ntawm ntau yam kab mob.
2. Kev tiv thaiv hluav taws xob, tiv thaiv daim tawv nqaij los ntawm kev yees duab
Tib neeg tau paub ntev ntev tias cov hluav taws xob ultraviolet yog ib qho tseem ceeb ua rau kev yees duab epidermal thiab mob qog noj ntshav. Thaum lub sij hawm kev loj hlob ntawm daim tawv nqaij, vim raug ultraviolet nuclear rays, deterioration ntawm lub nyob ib puag ncig thiab lwm yam yog vim li cas, lipids, collagen, thiab lwm yam nyob rau hauv lub hlwb yuav undergo oxidation tshua thiab tsim ib tug loj npaum li cas ntawm dawb radicals. Yog tias cov dawb radicals tsis raug tshem tawm hauv lub sijhawm, daim tawv nqaij yuav puas. Yuav muaj cov cim qhia ntawm sagging, wrinkles, xim av me ntsis, melanin deposition, dull daim tawv nqaij, thiab lwm yam. Qhov no yog photoaging ntawm daim tawv nqaij.
Cov kev tshawb fawb tau pom tias astaxanthin muaj zog antioxidant kev ua haujlwm 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.
Lub super antioxidant kev ua ntawm ntuj astaxanthin tso cai rau cov tawv nqaij tawv los tiv thaiv oxidation txij thaum pib, nyob deb ntawm kev puas tsuaj ntawm dawb radicals, thiab muaj zog whitening, freckle tshem tawm, wrinkle tshem tawm, thiab ncua kev laus ntawm daim tawv nqaij.
3. Astaxanthin tiv thaiv qhov muag thiab txhim kho kev pom
Tib neeg retina muaj ntau dua polyunsaturated fatty acids thiab ntau dua cov pa oxygen dua li lwm cov ntaub so ntswg. Thaum tib neeg lub cev siv nws lub qhov muag ntev ntev, oxygen dawb radicals tsim los ntawm cov duab-oxidation yuav ua rau peroxidative puas tsuaj rau lub retina. Rau tib neeg thiab lwm yam tsiaj, kev noj haus carotenoids yog tsim nyog los tswj qhov muag. Lawv cov khoom antioxidant tuaj yeem tua cov kab mob uas ua rau cov pa oxygen puas tsuaj thiab pab tiv thaiv retina tiv thaiv oxidative puas tsuaj. Astaxanthin yog carotenoid uas muaj zog tshaj plaws antioxidant kev ua nyob rau hauv cov xwm. Nws tuaj yeem dhau los ntawm cov hlab ntsha-hlwb thaiv thiab tiv thaiv cov retinal oxidation thiab photoreceptor cell puas, yog li tiv thaiv ntau yam kab mob ntawm qhov muag, xws li myopia, vertigo, cataracts, thiab lwm yam tshwm sim.
4. Tiv thaiv lub hauv paus paj hlwb thiab tiv thaiv lub hlwb qaug zog
Lub hauv paus paj hlwb (xws li lub paj hlwb, qaum qaum, thiab cov hlab ntsha peripheral) yog nplua nuj nyob rau hauv unsaturated fatty acids thiab hlau, muaj cov metabolism hauv siab, thiab muaj kev cuam tshuam rau oxidative puas tsuaj, ua rau muaj kev ntxhov siab thiab kev puas tsuaj rau lub paj hlwb. Nws ua rau tib neeg lub cev ua haujlwm ntau ntawm kev puas siab puas ntsws, xws li nkees nkees thaum ua haujlwm lossis kawm ntawv ntev, txo cov lus teb xav, thiab nco tsis tau.
Astaxanthin muaj peev xwm tiv thaiv lub hauv paus paj hlwb, tshwj xeeb tshaj yog lub hlwb thiab qaum. Astaxanthin tuaj yeem tiv thaiv kev qaug zog ntawm lub paj hlwb thiab kev xav qeeb, ua kom lub siab, tiv thaiv kev qaug zog, ua kom lub sijhawm ua haujlwm zoo ntawm tib neeg lub cev, thiab txhim kho kev ua haujlwm.
5. Tshem tawm kev qaug zog thiab pab kom lub cev rov qab muaj zog sai
Thaum tib neeg lub cev koom nrog kev tawm dag zog lub cev lossis kev tawm dag zog rau lub sijhawm ntev, kev tawm dag zog cov leeg nqaij yuav tsim ntau cov dawb radicals. Yog tias cov dawb radicals tsis tau ua tiav los ntawm cov tshuaj antioxidants hauv lub sijhawm, lawv yuav ua rau oxidative kev nyuaj siab, ua rau cov leeg mob los yog kev puas tsuaj rau cov leeg nqaij.
Kev tawm dag zog aerobic muaj zog tuaj yeem ua rau muaj kev tsim cov pa oxygen reactive (ROS) los ntawm ntau lub tshuab. ROS tsim los ntawm cov kev tawm dag zog no tuaj yeem oxidize ntau lub hom phiaj hauv tib neeg lub cev xws li protein, rog, thiab DNA, ua rau muaj kev puas tsuaj rau pob txha pob txha, lub plawv, thiab daim siab.
Kev tshawb fawb pom tau tias cov tshuaj antioxidants xws li cov vitamins E, C, thiab carotenoids tuaj yeem txo oxidative puas tsuaj. Raws li lub zog antioxidant, ntuj astaxanthin muaj cov txiaj ntsig tseem ceeb tshaj plaws hauv qhov no. Astaxanthin tuaj yeem ua rau cov leeg nqaij muaj zog thiab ua rau cov leeg mob, rov qab los ntawm kev tawm dag zog kom sai, thiab txo qis qhov mob ntawm cov leeg nqaij (DOMS) tom qab qoj ib ce.
6. Anti-inflammatory zog
Mob pob qij txha thiab mob caj dab feem ntau tshwm sim los ntawm oxidative puas tsuaj los ntawm cov dawb radicals. Cov dawb radicals yog tsim vim raug rau cov pa phem los yog muaj teeb meem nrog lub cev tiv thaiv kab mob. Ntawm ib sab, dawb radicals rhuav tshem cov kab mob pathogenic thiab kab mob; ntawm qhov tod tes, lawv tawm tsam cov qe ntshav dawb lawv tus kheej, ua rau lawv tuag loj heev. Raws li qhov tshwm sim, lawv ua rau ntau qhov tso tawm ntawm lysosomal enzymes ntxiv rau kev puas tsuaj lossis tua cov hlwb, ua rau cov pob txha thiab pob txha puas tsuaj thiab ua rau mob. thiab mob caj dab.
Lub zog antioxidant zog ntawm astaxanthin tuaj yeem pab tiv thaiv cov dawb radicals thiab txo cov oxidative puas hlwb rau cov hlwb, yog li tiv thaiv qhov tshwm sim ntawm ntau yam mob, xws li mob caj dab thiab prostatitis.
7. Kev tiv thaiv kab mob plawv thiab cerebrovascular
Kev tshawb fawb kho mob ntawm kev tiv thaiv kab mob arteriosclerosis thiab lwm yam kab mob qhia tau hais tias oxidation ntawm low-density lipoprotein (LDL) yog ib qho tseem ceeb ua rau arteriosclerosis. Yog tias qhov concentration ntawm lipoprotein tsawg ntom hauv tib neeg lub cev yog siab, qhov kev pheej hmoo ntawm atherosclerosis yog siab dua, uas ua rau cov phab ntsa ntawm cov hlab ntsha puas. Tsis tas li ntawd, cov hlab ntsha ua thinner vim platelet deposition, uas nws thiaj li thaiv cov ntshav khiav hauv cov hlab ntsha thiab ua rau mob plawv. kab mob thiab mob stroke. Ntawm qhov tod tes, yog tias cov ntsiab lus ntawm HDL hauv cov ntshav siab dua, txoj hauv kev ntawm cov kab mob coronary artery yuav txo qis, yog li tiv thaiv qhov tshwm sim ntawm atherosclerosis.
Cov tshuaj antioxidant muaj zog ntawm astaxanthin tuaj yeem txo cov oxidation ntawm apolipoproteins thiab tuaj yeem siv los ua kev npaj los tiv thaiv kev kub ntxhov, hyperlipidemia, arteriosclerosis, kab mob plawv thiab ischemic hlwb puas.
8. Tiv thaiv cov kab mob metabolic xws li ntshav qab zib thiab gout
Cov metabolism hauv tib neeg lub cev yog nrog los ntawm ntau yam oxidation tshwm sim ntawm cov hlwb. Yog tias qhov loj ntawm cov dawb radicals tsim los ntawm cov cell oxidation tsis tuaj yeem ua tiav raws sijhawm, lawv yuav tawm tsam cov rog, protein, DNA thiab lwm yam macromolecules hauv cov hlwb. Yog tias lub cev tsis tuaj yeem ua cov txheej txheem oxidation thiab tawm tsam hauv lub sijhawm, cov hlwb, yog tias muaj ntau yam zoo li no, ntau yam kab mob metabolic yuav tshwm sim, xws li ntshav qab zib, gout, thiab lwm yam.
Astaxanthin lub zog tshem tawm cov nyhuv ntawm cov dawb radicals hauv lub cev tuaj yeem tiv thaiv qhov tshwm sim ntawm cov kab mob metabolic no thiab ua kom lub cev noj qab haus huv.
