Yog tias koj puas tau sawv hauv qhov chaw ntxiv piv piv cov fwj zinc, koj yuav tau nug koj tus kheej:Hom zinc twg yog qhov zoo tshaj plaws?
Zinc picolinate hmoovyog nyob tsis tu ncua ntawm cov bioavailable tshaj plaws thiab kev tshawb fawb-cov ntaub ntawv ntawm zinc. Tab sis dab tsi raws nraim nws sib nrug ntawm zinc gluconate, zinc citrate, lossis zinc bisglycinate? Thiab qhov tseem ceeb tshaj,science tiag tiag hais li castxog nws cov txiaj ntsig, kev noj tshuaj kom zoo, thiab ntev -kev nyab xeeb?
Phau ntawv qhia no teb cov lus nug no nrog cov phooj ywg -cov pov thawj tshuaj xyuas, cov ntsiab lus ntawm kev tswj hwm thoob ntiaj teb, thiab kev nkag siab txog kev tsim qauv. Tsis muaj hype, tsis muaj kev lag luam fluff- tsuas yog qhov tseeb koj yuav tsum tau txiav txim siab paub txogZinc Picolinate hmoov.
Zinc Picolinate yog dab tsi? Chemistry & Absorption Advantage
Zinc picolinate hmoovyog ib qho kev sib koom ua ke ntawm zinc chelated nrogpicolinic acid-natural metabolite ntawm amino acid tryptophan. Nws cov mis molecular yog C₁₂H₈N₂O₄Zn, nrog lub cev hnyav ntawm 309.58 g / mol thiab CAS tus lej 17949-65-4.
Kev Sib Txuas Picolinate: Kev Tshawb Fawb los ntawm Tib Neeg Mis
Qhov laj thawj rau picolinate chelation tsis yog qhov kev txiav txim siab - nws yog hauv paus hauv tib neeg lub cev. Hauv1980, cov kws tshawb fawb Evans thiab Johnson tau cais tawm thiab pom qhov qis -molecular- hnyav zinc- khi ligand los ntawm tib neeg cov mis nyuj. Siv loj spectroscopy, nyias- txheej chromatography, thiab infrared spectroscopy, lawvua pov thawj no ligand yog picolinic acid [1].
Cov ntsiab lus tseem ceeb ntawm qhov kev tshawb nrhiav thaj chaw no:
- Concentration nyob rau hauv tib neeg mis nyuj:308 μM
- Concentration nyob rau hauv tiav nyuj cov mis nyuj:20 μM(ib hom) rau undetectable (lwm tus qauv / me nyuam mos mis)
- Weanling nas pub ntxiv picolinic acid absorbedtseem ceeb tshaj kev noj zaub mov zincthiab tau hnyav hnyav dua[1].
Xaus:Qhov siab bioavailability ntawm zinc nyob rau hauv tib neeg cov mis nyuj tshwm sim los ntawm muaj picolinic acid-abidentate chelate liganduas pab txhawb txoj hnyuv plab zom mov[1].
Qhov no yog qhovmolecular foundationvim li cas zinc picolinate ua tau zoo dua lwm cov ntaub ntawv:nws ua raws li lub cev tus kheej cov txheej txheem rau kev noj cov zinc zoo.
Bioavailability: Zinc Picolinate Sib piv li cas?
Xyoo 1987Barrie et al. kev sim tshuajluam tawm nyob rau hauvTus neeg sawv cev thiab kev uatseem yog qhov ncaj tshaj kev sib piv tib neeg txoj kev tshawb fawb txog niaj hnub no[4].
