1. Huru nzira yekuita

Hydroxylation reaction catalysis

Vitamin C ndiyo yakakosha coenzyme yekugadzira collagen, iyo inosimudzira hydroxylation yeamino acid parutivi cheni muma collagen mamorekuru nekugadzirisa hydroxylation reaction yeproline uye lysine, ichigadzira yakagadzikana katatu helix chimiro.

Hydroxylated collagen ine simba rakasimba remuchina uye kugadzikana, iyo inogona kunyatso kuchengetedza kusimba uye kusimba kwematishu akadai seganda, mapfupa, uye tsinga dzeropa.

Antioxidant kudzivirira

Vitamin C inoderedza mahara radicals, inoderedza oxidative kukuvara kune collagen, uye inonoke kuchembera kweganda uye kuwedzera vascular fragility inokonzerwa neoxidative kusagadzikana.

2、 Kukanganisa kwesangano uye hutano

Utano Hweganda

Nekusimudzira collagen synthesis, kuchengetedza elasticity uye kusimba kweganda, kuderedza kuunyana kuumbwa, uye kukurumidza kuporesa maronda.

Mabhonzo nemajoini

Collagen chinhu chakakosha chepfupa matrix, uye kubatanidzwa kwevhitamini C kunogona kuwedzera kusimba kwepfupa, kuderedza dambudziko rekuputsika, uye kuchengetedza kushanduka kwejoka rekubatana.

Vascular function

Collagen inopa tsigiro yemadziro emidziyo yeropa, uye vhitamini C inodzikamisa chimiro chayo kudzivirira microvascular hosha dzakadai sevascular fragility uye gum kubuda ropa.

3, Kushaya uye Supplementary Mazano

Kusabatana nezviratidzo

Kushaikwa kwenguva refu kwevhitamini C kunogona kutungamira kune collagen synthesis kusagadzikana uye kukonzeresa scurvy, nezviratidzo zvakajairwa zvinosanganisira kubuda kwegum, maronda eganda, uye kunonoka kuporesa maronda.

Inonzwisisika yekuwedzera nzira

Dietary source: Kudya kwezuva nezuva kwezvibereko zvitsva nemiriwo yakawanda muvhitamini C (yakadai sekiwi, citrus, broccoli, nezvimwewo), inokurudzirwa kudya yakasvibira kana kuti yakagadziridzwa zvishoma kuderedza kurasikirwa kwezvokudya.

Kuwedzera kushandiswa: Vakuru vanokurudzirwa kushandisa 100mg pazuva. Special populations (zvakadai sevakadzi vane pamuviri uye postoperative varwere) vanogona kugadzirisa dosage maererano nezano rekurapa kuti vadzivise njodzi yekudya zvakanyanya inotungamira kumatombo eitsvo uye mamwe matambudziko.
