Vitamin B (vitamin B) yog ib yam khoom tseem ceeb rau cov metabolism hauv carbohydrates, cov rog thiab cov proteins hauv tib neeg lub cev. Feem ntau ntawm cov vitamins B yog soluble hauv dej, suav nrog vitamin B1 (Thiamine), vitamin B2 (Riboflavin), vitamin B3 (Niacin), vitamin B4 (Aminopurine phosphate), vitamin B5 (Pantothenic acid, Pentosan) acid), vitamin B6 ( Pyridoxine), vitamin B7 (vitamin H), vitamin B8 (Adenine nucleotide), vitamin B11 (Folate), vitamin B12 (Cobalamins) thiab lwm yam.
Ntawm cov vitamins B ntau, vitamin B1, vitamin B2, vitamin B3, vitamin B5, vitamin B6, vitamin B11 thiab vitamin B12 feem ntau siv los ntawm tib neeg lub cev, thiab vim coenzymes ua lub luag haujlwm tseem ceeb hauv cov metabolism ntawm carbohydrates, cov rog thiab cov proteins. nyob rau hauv tib neeg lub cev.
Dab tsi yog yam uas cuam tshuam rau kev ruaj ntseg ntawm cov vitamins?
Cov vitamins yog yooj yim oxidized los yog txo thaum lub sij hawm cia vim hais tias lawv cov qauv molecular muaj hydroxyl pawg, unsaturated ob daim ntawv cog lus thiab lwm yam khoom uas rhiab heev rau cov tshuaj tiv thaiv, xws li lub teeb, tshav kub, pH, ya raws thiab kab kawm. Cov yam ntxwv no cuam tshuam rau kev ruaj ntseg ntawm cov vitamins. Cov kev cuam tshuam no yuav rhuav tshem cov qauv ntawm cov vitamin molecules los ntawm kev sib txawv ntawm cov tshuaj tiv thaiv, xws li cov tshuaj tiv thaiv photochemical, cov tshuaj tiv thaiv hloov hluav taws xob, cov tshuaj tiv thaiv dawb radical, thiab lwm yam.
Kev ruaj ntseg ntawm cov vitamins B yog ze ze rau pH, noo noo thiab kab kawm ntawm lawv cov kev daws teeb meem. Piv txwv li, vitamin B1 thiab vitamin B2 yog qhov ruaj khov hauv cov kua qaub; vitamin B5 thiab vitamin B11 kuj ruaj khov nyob rau hauv tsis muaj zog alkaline tov, tab sis tsis ruaj khov nyob rau hauv photothermal tej yam kev mob. Yog hais tias lub premix muaj ib tug kab ntawm choline, vitamin B4 hydrochloride thiab B6 yuav decompose sai, tab sis yog hais tias cov dej cov ntsiab lus nyob rau hauv lub premix yog tsawg, nws kuj yog ruaj khov. Vitamin B2 nyob rau hauv premix yog qhov ruaj khov nyob rau hauv kub thiab high humidity tej yam kev mob. Vitamin B11 yog qhov nkag siab zoo rau dej, noo noo, lub teeb thiab txo cov neeg ua haujlwm, tsis ruaj khov hauv cov kua qaub, thiab ruaj khov nyob rau hauv qhov kub thiab txias.
Nws tuaj yeem pom tias qhov tseem ceeb tshaj plaws uas cuam tshuam rau kev ruaj ntseg ntawm cov vitamins yog ya raws thiab oxygen hauv huab cua, nrog rau cov tshuaj tiv thaiv redox tshwm sim los ntawm cov kab mob.
