Fa'aaogaina o oloa
1. Ascorbic acid, lea e taʻua foi o le vitamini C, e tautuaina galuega taua i le tino o le tagata. E galue e pei o se antioxidant, o se cofactor mo le tele o gaioiga enzymatic, o se coenzyme, o se mea e togafitia ai le falaoamata, o se meaʻai antioxidant, o se metabolite o laʻau, o se mea e faʻamalamalama ai le paʻu, ma se mea e taofi ai le lanu o meaʻai.
2.Ascorbic acid o se faʻalapotopotoga faʻapitoa o loʻo i le vaega o le polyhydroxy alcohols unsaturated. O se ketolactone e mafai ona solu i le vai ma se mama kaponi e lima ona sui. E malosi fa'aitiitiga meatotino ona o fusi fa'alua i le C2 ma C3 carbons ma fa hydroxyl vaega. O le ascorbic acid e avea o se hydrogen po'o se electron donor, ma avea ai ma se fa'ameamea i le tele o gaioiga fa'aenzymatic.
3. E ui o le tele o mammals e mafai ona gaosia le ascorbic acid mai le kulukose, e le maua e tagata le enzyme talafeagai ma e tatau ona maua mai a latou meaʻai. Ole mana'oga ile aso ole ascorbic acid e eseese, ma fafine e mana'omia ile 75 mg ma alii ile 90 mg. E ui o fualaau suamalie e masani ona fesoʻotaʻi ma le ascorbic acid, o isi fualaʻau, fualaau faisua, ma aano o manu e fai ma meaʻai.
4. O le acid ascorbic ose mea taua e maualalo-molecular-weight antioxidant e faʻatonutonu ai le maualuga o ituaiga okesene faʻafoʻi (ROS) ma faʻaleleia le aoga o isi antioxidants. E iai sona sao i tulafono faatonutonu a le ROS i lo latou tulaga fa'avaeina ma foa'i se tasi fa'aitiitiga tutusa. E faaosofia ai le gaioiga o enzymes antioxidant pei o le superoxide dismutase (SOD) ma e taua tele mo le faʻaogaina o collagen.
afifi ma teuina
afifi:
25kg/carton pa'u po'o lou mana'oga.
Fa'amatalaga: Fa'asologa o vaila'au ma le tele e mafai ona fa'amalieina e mana'oga o tagata fa'atau
Teuina:
Vaevae mai oxidants malosi ma faavae malosi.Solusi o le ascorbic acid e vave oxidized i le ea ma i ala o faasalalauga alkaline; e tatau ona puipuia le fualaau mai le ea ma le malamalama.
