Biotin yog tsim nyog rau kev loj hlob ntawm tes, tsim cov fatty acids, thiab cov metabolism ntawm cov rog thiab amino acids.Nws ua lub luag haujlwm hauv lub voj voog citric acid, uas yog cov txheej txheem uas lub zog biochemical tsim tawm thaum lub sij hawm ua pa aerobic.Biotin yog coenzyme rau carboxylase enzymes, koom nrog hauv kev sib txuas ntawm fatty acids, isoleucine, thiab valine, thiab hauv gluconeogenesis.Tsis tas li ntawd, biotin tau dav siv thoob plaws hauv kev lag luam biotechnology los sib txuas cov proteins rau kev kuaj biochemical.
Peb xav tau biotin txog 100 mus rau 300 micrograms ib hnub.Muaj cov tshuaj tua kab mob protein uas tuaj yeem ua ke nrog biotin hauv cov qe dawb.Tom qab sib txuas, nws tsis tuaj yeem nqus los ntawm lub plab zom mov;ua rau tsiaj biotin tsis txaus, tib lub sij hawm poob qab los noj mov, glossitis, dermatitis dermatitis, tshem tawm cov plaub hau thiab lwm yam.Txawm li cas los xij, tsis muaj qhov tsis txaus ntawm biotin rau tib neeg, tej zaum vim tias ntxiv rau cov khoom noj, cov kab mob hauv plab kuj tuaj yeem tsim cov biotin.Biotin yog coenzyme ntawm ntau cov enzymes hauv tib neeg lub cev.Nws koom nrog hauv cov metabolism ntawm aliphatic acid, carbohydrate, vitamin B12, folic acid thiab pantothenic acid;txhawb nqa synthesis ntawm protein thiab urea, thiab kuj txhawb excretion.
Pab rog, glycogen thiab amino acids rau ib txwm synthesis thiab metabolism hauv tib neeg lub cev;
Txhawb kev ua haujlwm ib txwm muaj thiab kev loj hlob ntawm hws qog, paj hlwb, pob txha pob txha, txiv neej gonads, tawv nqaij thiab plaub hau, thiab txo cov tsos mob ntawm eczema, dermatitis;
Tiv thaiv cov plaub hau dawb thiab plaub hau poob, pab txhawb kev kho mob ntawm baldness;
Txo cov leeg mob;
Txhawb nqa synthesis thiab excretion ntawm urea, purine synthesis thiab oleic acid biosynthesis;
Rau kev kho mob ntawm atherosclerosis, mob stroke, dyslipidemia, kub siab, kab mob plawv thiab ntshav ncig tsis zoo.
