Ukusetshenziswa Kwemikhiqizo
1.I-Ascorbic acid, eyaziwa nangokuthi uvithamini C, yenza imisebenzi ehlukahlukene ebalulekile emzimbeni womuntu. Isebenza njenge-antioxidant, i-cofactor yokusabela okuningi kwe-enzymatic, i-coenzyme, i-ejenti yokwelapha ufulawa, i-antioxidant yokudla, i-metabolite yesitshalo, i-ejenti ekhanyisa isikhumba, kanye ne-ejenti yokugcina umbala wokudla.
2.I-Ascorbic acid iyinhlanganisela ye-organic eyingxenye ye-unsaturated polyhydroxy alcohols. I-ketolactone encibilika emanzini enendandatho yekhabhoni enamalungu amahlanu. Inezakhiwo eziqinile zokunciphisa ngenxa yamabhondi aphindwe kabili ku-C2 kanye ne-C3 carbons kanye namaqembu amane e-hydroxyl. I-Ascorbic acid isebenza njenge-hydrogen noma i-electron donor, iyenze ibe yi-cofactor ekuphenduleni okuningi kwe-enzymatic.
3. Nakuba izilwane ezincelisayo eziningi zingakhiqiza i-ascorbic acid ku-glucose, abantu abanayo i-enzyme edingekayo futhi kufanele bayithole ekudleni kwabo. Isidingo sansuku zonke sokudla kwe-ascorbic acid siyahlukahluka, kanti abesifazane badinga cishe ama-75 mg kanti amadoda adinga ama-90 mg. Nakuba izithelo ezisawolintshi zivame ukuhlotshaniswa ne-ascorbic acid, ezinye izithelo, imifino, kanye nenyama nazo zisebenza njengemithombo yokudla.
4. I-Ascorbic acid iyi-antioxidant eyisihluthulelo enesisindo esiphansi elawula amazinga ezinhlobo ze-oxygen esebenzayo (ROS) futhi ithuthukise ukusebenza kahle kwamanye ama-antioxidants. Idlala indima ekulawuleni i-ROS esigabeni sokubunjwa futhi inikele ngokulingana okukodwa kokunciphisa. Ivuselela umsebenzi wama-enzyme e-antioxidant njenge-superoxide dismutase (SOD) futhi ibalulekile ekuhlanganiseni kwe-collagen.
Iphakheji Nesitoreji
Iphakheji:
25kg/ibhokisi lesigubhu noma njengezidingo zakho.
Phawula: Ukwakheka kwekhemikhali nosayizi kungenziwa ngokugcwele ngezidingo zamakhasimende
Isitoreji:
Ihlukaniswe nama-oxidants aqinile nezisekelo eziqinile.Izixazululo ze-ascorbic acid zikhishwa ngokushesha emoyeni nasemithonjeni ye-alkaline; umuthi kufanele uvikeleke emoyeni nasekukhanyeni.
Ukuvikela Ukuphepha
Izinyathelo zokuphepha zokuphatha okuphephile
AKUKHO amalangabi avulekile. Ukuphatha endaweni enomoya omuhle. Gqoka izingubo ezifanele zokuzivikela. Gwema ukuthinta isikhumba namehlo. Gwema ukwakheka kothuli nama-aerosol. Sebenzisa amathuluzi angashiyi izinhlansi. Vimbela umlilo obangelwa umusi wokukhipha i-electrostatic.
