1. Analytical reagents na mmeghachi omume usoro

Onye na-ebelata ihe na ihe mkpuchi

A na-ejikar? vitamin C eme ihe d? ka ihe na-ebelata ike n'ime ?l? nyocha iji wep? ihe nd? na-eme ka ihe na-eme ka ? ghara ?d? na-ekpo ?k? (d? ka ayodiin elemental), na enwere ike nyochaa ngbanwe ya site na nyocha nke na-ebelata iodine.

Na complexometric titration, vitamin C nwere ike ije ozi d? ka ihe nkpuchi iji kpochap? nnyonye anya nke ion ígwè na nch?p?ta ah?.

Nnyocha na Redox Reaction

Mkpebi ?n??g? nke ?d?naya vitamin C site na mmeghachi omume mbelata oxidation na ayodiin elemental (d? ka usoro iodometric) ka a na-eji n'?t?t? ebe na nyocha nke nri na ihe nlele.

2. Nch?p?ta nkà na ?z? na ngwa ndap?ta

Mmepe nke ?z? nch?p?ta ?n??g?

Nnwale biomedical: iji UV spectrophotometry, chromatography mmiri na-ar? ?r? d? elu (HPLC), wdg, iji ch?p?ta nke ?ma ?d?naya vitamin C d? na serum na an? ah?, na-enyere aka nyocha ?l? ?gw? (d? ka scurvy).

Nyocha nri na ihe ?ch? mma: Nyochaa nkw?si ike na uru vitamin C d? na mkp?r? osisi, akw?kw? nri, na ihe ?ch? mma site na iji ?la k?pa oxidation colorimetric ma ? b? ?z? chromatography mmiri.

Nnyocha Physiology Osisi

Ch?p?ta ?d?naya vitamin C d? na an? ah? osisi iji nyochaa mmet?ta nr?gide gburugburu ebe obibi (d? ka ?k? mmiri ozuzo, mmet? ígwè d? ar?) na sistemu antioxidant osisi.

3. Nkwadebe usoro na mmep?ta mmepe

Nkwalite usoro nkwadebe ?l? nyocha

?nabata tekn?z? na-ehicha friza iji kwalite nkw?si ike nke vitamin C reagents, na iwepu ad?gh? ?cha site na pretreatment carbon ar? ?r? iji h? na nchoputa ziri ezi.

Z?lite ?d? usoro onunu ogwu ?h?r? d? ka usoro mkpuchi nke enteric na granules iji kwalite bioavailability nke vitamin C.

Mmep?ta ngwaah?a ?k?l?t? na ngwa reagent

Ngwa reagent ahaziri ahazi (d? ka ngwa nch?p?ta vitamin C) jik?tara ya na alg?ridim ?g?g? isi na-enyere aka nyocha nke ?ma nke ?d? nlele buru ibu.

4. Nnwale nyocha na njikwa mma

Usoro nkwado

Nyochaa izi ezi nke usoro nch?p?ta ah? site na nnwale mgbake spiked (?n?ego mgbake nke 95.6% ~ 101.0%).

T?lee ?z? d? iche iche d? ka 2,4-dinitrophenylhydrazine colorimetric usoro na iodometric usoro iji h? na a p?r? ?dabere na ya p?ta.

Njikwa ihe ntinye aka

Welie ?n?d? mmeghachi omume (d? ka pH na okpom?k?) iji belata nnyonye anya sitere na ihe nd? ?z? na-ebelata ihe (d? ka glutathione).

Nch?k?ta: Vitamin C nwere ma reagent ?r? na nyocha ihe Njirimara na laabu. Tekn?z? nch?p?ta ya, usoro nkwadebe, na nyocha usoro mmeghachi omume na-enye nkwado tekn?z? b? isi maka biomedical, sayens? nri, na mpaghara nd? ?z?.
