1, Core mechanism ntawm kev txiav txim

Hydroxylation cov tshuaj tiv thaiv catalysis

Vitamin C yog ib qho tseem ceeb coenzyme rau collagen ntau lawm, uas txhawb lub hydroxylation ntawm amino acid sab chains nyob rau hauv collagen molecules los ntawm catalyzing hydroxylation cov tshuaj tiv thaiv ntawm proline thiab lysine, tsim ib tug ruaj khov triple helix qauv.

Hydroxylated collagen muaj zog txhua yam muaj zog thiab ruaj khov, uas tuaj yeem tswj cov elasticity thiab tawv tawv ntawm cov ntaub so ntswg xws li tawv nqaij, pob txha, thiab cov hlab ntsha.

Antioxidant tiv thaiv

Vitamin C neutralizes dawb radicals, txo oxidative kev puas tsuaj rau collagen, thiab ncua kev laus ntawm daim tawv nqaij thiab nce vascular fragility tshwm sim los ntawm oxidative kev nyuaj siab.

2, Kev cuam tshuam rau lub koom haum thiab kev noj qab haus huv

Kev noj qab haus huv ntawm daim tawv nqaij

Los ntawm kev txhawb nqa collagen synthesis, tswj ntawm daim tawv nqaij elasticity thiab firmness, txo wrinkle tsim, thiab accelerating qhov txhab kho.

Cov pob txha thiab pob qij txha

Collagen yog ib qho tseem ceeb ntawm pob txha matrix, thiab kev koom tes ntawm cov vitamin C tuaj yeem txhim kho pob txha ceev, thiab tswj qhov kev pheej hmoo ntawm kev sib xyaw ua ke ntawm pob txha pob txha mos.

Vascular muaj nuj nqi

Collagen muab kev txhawb nqa rau phab ntsa hlab ntsha, thiab vitamin C stabilizes nws cov qauv los tiv thaiv cov kab mob microvascular xws li vascular fragility thiab cov pos hniav los ntshav.

3. Tsis muaj thiab cov lus qhia ntxiv

Tsis muaj kev koom tes nrog cov tsos mob

Lub sij hawm ntev vitamin C tsis txaus tuaj yeem ua rau muaj kev cuam tshuam ntawm collagen synthesis thiab ua rau scurvy, nrog rau cov tsos mob xws li cov pos hniav los ntshav, daim tawv nqaij bruising, thiab qeeb qhov txhab kho.

Tsim nyog cov channel ntxiv

Dietary Source: Kev noj cov txiv hmab txiv ntoo tshiab thiab zaub txhua hnub uas muaj vitamin C (xws li kiwi, citrus, broccoli, thiab lwm yam), nws raug nquahu kom noj cov nqaij nyoos los yog maj mam ua kom txo cov as-ham.

Kev siv ntxiv: Cov neeg laus raug pom zoo kom haus 100mg ib hnub. Cov neeg tshwj xeeb (xws li cov poj niam cev xeeb tub thiab cov neeg mob tom qab phais) tuaj yeem kho qhov ntau npaum li cas raws li cov lus qhia kho mob kom tsis txhob muaj kev pheej hmoo ntawm kev noj ntau dhau ua rau lub raum pob zeb thiab lwm yam teeb meem.
