ʻO ka wahi hoʻomaka no ka synthesis o ka huaʻaʻa C ʻo ia ke koho ʻana i ka hoʻoheheʻe ʻana o ka hui kō D-sorbit i L-sorbose me ka hoʻohana ʻana i ka bacteria Acetobacter suboxidans.Hoʻololi ʻia ʻo L-sorbose i L-ascorbic acid, ʻoi aku ka maikaʻi o ka huaora C.
ʻO ka sodium, potassium, a me ka paʻakai calcium o nā waikawa ascorbic i kapa ʻia ʻo ascorbates a hoʻohana ʻia e like me nā mea mālama meaʻai.No ka hana ʻana i ka momona ascorbic acid, hiki ke esterified.ʻO nā Esters o ka waikawa ascorbic a me nā waikawa, e like me ka palmitic acid e hana i ka ascorbyl palmitate a me ka stearic acid e hana i ka ascorbic stearate, hoʻohana ʻia e like me nā antioxidants i ka meaʻai, nā lāʻau lapaʻau, a me nā mea hoʻonaninani.He mea nui ka ascorbic acid i ka metabolism o kekahi mau amino acids.Kōkua ia i ka pale ʻana i nā cell mai ka pōʻino radical manuahi, kōkua i ka hao hao, a he mea nui ia no nā kaʻina metabolic he nui.
ʻO ka Vitamin C kahi anti-oxidant kaulana.ʻAʻole i maopopo maopopo kona hopena i ka hoʻokumu ʻana i ka free-radical i ka wā i hoʻopili ʻia i ka ʻili ma o ka cream.Ua nīnau ʻia ka maikaʻi o nā noi topical ma muli o ka paʻa ʻole o ka huaora C (e hana me ka wai a hoʻohaʻahaʻa).Ua ʻōlelo ʻia kekahi mau ʻano ʻoi aku ka maikaʻi o ka paʻa i nā ʻōnaehana wai.ʻO nā analogues synthetic e like me ka magnesium ascorbyl phosphate i waena o nā mea i manaʻo ʻia he ʻoi aku ka maikaʻi, no ka mea, ʻoi aku ka paʻa.I ka loiloi ʻana i kona hiki ke hakakā i ka pōʻino free-radical ma muli o kona hopena synergistic me ka huaʻaʻa e, ʻālohilohi ka huaora C.E like me ka huaora e reacts me ka noa radical, ia mea, ua poino e ka noa radical ia e kaua ana.Hele mai ka Vitamin C no ka hoʻoponopono ʻana i ka pōʻino free-radical i loko o ka huaora e, e ʻae iā e e hoʻomau i kāna mau hana hoʻoheheʻe manuahi.Ua hōʻike ʻia nā noiʻi i hala aku nei he photoprotective ka nui o ka nui o ka huaora C i hoʻohana ʻia ma luna, a ʻo ka hoʻomākaukau ʻana i ka huaora i hoʻohana ʻia i kēia mau haʻawina i kūʻē i ke kopa a me ka wai, ka holoi ʻana, a i ʻole ka hamo ʻana i nā lā ʻekolu.Ua hōʻike ʻia nā noiʻi hou aʻe e hoʻohui ka huaora C i ka pale ʻana i ka pōʻino uVB ke hui pū ʻia me nā kemika pale uVB.E alakaʻi kēia i kekahi e hoʻoholo i ka hui pū ʻana me nā lāʻau pale lā maʻamau, hiki i ka huaora C ke ʻae i ka pale ʻana i ka lā lōʻihi.Eia hou, ʻo ka synergy ma waena o nā huaora C a me e hiki ke hāʻawi i nā hopena maikaʻi aʻe, ʻoiai ʻo ka hui pū ʻana o nā mea ʻelua e pale maikaʻi loa mai ka pōʻino uVB.Eia naʻe, ʻoi aku ka maikaʻi o ka huaora C ma mua o ka pale ʻana i ka pōʻino uVA.ʻO ka hopena hou aʻe, ʻo ka hui pū ʻana o nā huaora C, e, a me ka pale lā e hāʻawi i ka pale ʻoi aku ma mua o ka huina o ka pale i hāʻawi ʻia e kekahi o nā mea ʻekolu e hana wale ana.Hana pū ka Vitamin C ma ke ʻano he collagen biosynthesis regulator.Ua ʻike ʻia e hoʻomalu i nā mea colloidal intercellular e like me ka collagen, a i ka wā i hoʻopili ʻia i loko o nā kaʻa kūpono, hiki ke loaʻa ka hopena hoʻomālamalama ʻili.Ua ʻōlelo ʻia ʻo Vitamin C e hiki ke kōkua i ke kino e hoʻoikaika i nā maʻi maʻi ma o ka hoʻoikaika ʻana i ka ʻōnaehana pale.Aia kekahi mau hōʻike (ʻoiai ua hoʻopaʻapaʻa ʻia) hiki i ka huaora C ke hele i loko o nā ʻili o ka ʻili a hoʻoikaika i ka hoʻōla ʻana i ka ʻiʻo i hōʻino ʻia e ke kuni a i ʻole ka ʻeha.No laila, loaʻa ia i loko o nā ʻaila kuni a me nā holika i hoʻohana ʻia no nā abrasions.Ua kaulana pū ka Vitamin C i nā huahana anti-aging.Hōʻike nā haʻawina o kēia manawa i nā waiwai anti-inflammatory.
ʻO ka antioxidant physiological.ʻO Coenzyme no kekahi mau hopena hydroxylation;pono no ka hana collagen.Hoʻolaha nui ʻia i nā mea kanu a me nā holoholona.ʻO ka ʻai ʻole ka hopena i nā maʻi deficiency e like me ka scurvy.Hoʻohana ʻia e like me ka antimicrobial a me ka antioxidant i nā meaʻai.
