Ukusetyenziswa kweeMveliso
I-1.Ascorbic acid, eyaziwa ngokuba yi-vitamin C, ikhonza imisebenzi eyahlukeneyo ebalulekileyo emzimbeni womntu. Isebenza njenge-antioxidant, i-cofactor ye-enzymatic reactions ezininzi, i-coenzyme, i-agent yonyango yomgubo, i-antioxidant yokutya, i-metabolite yesityalo, i-agent ekhanyisa ulusu, kunye ne-arhente yokugcina umbala.
I-2.I-Ascorbic acid yi-organic compound eyeqela le-alcohol e-unsaturated polyhydroxy. I-ketolactone e-soluble yamanzi kunye nendandatho yekhabhoni enamalungu amahlanu. Unezakhiwo ezinamandla zokunciphisa ngenxa yokubambisana kabini kwi-C2 kunye ne-C3 carbons kunye namaqela amane e-hydroxyl. I-Ascorbic acid isebenza njenge-hydrogen okanye i-electron donor, iyenza ibe yi-cofactor kwiimpendulo ezininzi ze-enzymatic.
3. Ngelixa uninzi lwezilwanyana ezanyisayo zinokuvelisa i-ascorbic acid kwiglucose, abantu abanayo i-enzyme eyimfuneko kwaye kufuneka bayifumane ekudleni kwabo. Imfuno yemihla ngemihla ye-ascorbic acid intake iyahluka, kunye nabasetyhini abafuna malunga ne-75 mg kunye namadoda malunga ne-90 mg. Ngelixa iziqhamo ze-citrus ziqhelene ne-ascorbic acid, ezinye iziqhamo, imifuno kunye nenyama nazo zisebenza njengemithombo yokutya.
4. I-Ascorbic acid yi-antioxidant ephantsi ye-molecular-weight-weight elawula amanqanaba eentlobo ze-oxygen esebenzayo (ROS) kwaye iphakamisa ukusebenza kwamanye ama-antioxidants. Idlala indima kulawulo lwe-ROS kwinqanaba labo lokuqulunqa kwaye inikele ngokulinganayo kokunciphisa okulinganayo. Ivuselela umsebenzi we-antioxidant enzymes njenge-superoxide dismutase (SOD) kwaye ibalulekile kwi-collagen synthesis.
Ukupakishwa kunye noGcino
Umqulu:
25kg/igubu lebhokisi okanye njengeemfuno zakho.
Phawula: Ukwakhiwa kweekhemikhali kunye nobukhulu bunokulungiswa ngokweemfuno zabathengi
Ugcino:
Ukwahlulwe kwii-oxidants ezinamandla kunye neziseko eziqinileyo.Izisombululo ze-ascorbic acid zixutywe ngokukhawuleza emoyeni nakwimithombo ye-alkaline; iyeza kufuneka likhuselwe emoyeni nasekukhanyeni.
