1. ʻO ka waikawa Ascorbic, i kapa ʻia ʻo vitamin C, lawelawe i nā hana koʻikoʻi i loko o ke kino kanaka. Hana ia ma ke ʻano he antioxidant, he cofactor no nā hopena enzymatic he nui, he coenzyme, kahi mea mālama palaoa, kahi antioxidant meaʻai, kahi mea kanu metabolite, kahi mea hoʻomālamalama ʻili, a me kahi mea mālama kala meaʻai.
2.ʻO kaʻakika Ascorbic kahi mea hoʻohuihui no ka hui o nā waiʻona polyhydroxy unsaturated. He ketolactone hiki ke hoʻoheheʻe ʻia me ka apo kalapona ʻelima. Loaʻa iā ia nā waiwai hoʻemi ikaika ma muli o nā paʻa pālua ma nā kalapona C2 a me C3 a me nā hui hydroxyl ʻehā. Hana ʻia ka ʻakika Ascorbic ma ke ʻano he hydrogen a i ʻole electron hāʻawi, e hoʻolilo iā ia i cofactor i nā hopena enzymatic he nui.
3. ʻOiai hiki i ka hapa nui o nā mammals ke hana i ka waikawa ascorbic mai ka glucose, nele ke kanaka i ka enzyme pono a pono e loaʻa ia mai kā lākou ʻai. ʻOkoʻa ka koi o kēlā me kēia lā no ka lawe ʻana i ka waikawa ascorbic, me nā wahine e pono ai ma kahi o 75 mg a me nā kāne ma kahi o 90 mg. ʻOiai pili pinepine ʻia nā hua citrus me ka waikawa ascorbic, ʻo nā huaʻai ʻē aʻe, nā mea kanu, a me nā ʻiʻo e lawelawe pū me nā kumu meaʻai.
4. ʻO ka ʻakika Ascorbic kahi antioxidant haʻahaʻa haʻahaʻa-kaumaha nui e hoʻoponopono i nā pae o nā ʻano oxygen reactive (ROS) a hoʻonui i ka pono o nā antioxidants ʻē aʻe. He kuleana ko ia i ka hoʻoponopono ROS i ko lākou pae hoʻokumu ʻana a hāʻawi i kahi mea hoʻemi hoʻemi hoʻokahi. Hoʻoulu ia i ka hana o nā enzyme antioxidant e like me superoxide dismutase (SOD) a he mea koʻikoʻi ia no ka synthesis collagen.

Pūʻolo:
25kg / pahu pahu a i ʻole e like me kāu mau koi.
Manaʻo: Hiki ke hoʻopaʻa ʻia ka haku melemele a me ka nui e nā koi o nā mea kūʻai aku
Waihona:
Hoʻokaʻawale ʻia mai nā oxidants ikaika a me nā kumu ikaika. Hoʻopili koke ʻia nā mea hoʻonā o ka ascorbic acid i ka ea a me ka media alkaline; pono e pale ʻia ka lāʻau mai ka ea a me ka māmā.

Hoʻomalu no ka mālama pono ʻana
NO ke ahi hamama. ʻO ka lawelawe ʻana ma kahi wahi maikaʻi. E ʻaʻahu i nā lole pale kūpono. Hōʻalo i ka pili ʻana me ka ʻili a me nā maka. E pale i ka hana ʻana o ka lepo a me nā aerosol. E hoʻohana i nā mea hana ʻole. Kāohi i ke ahi i hana ʻia e ka mahu hoʻolele electrostatic.
