Chii chinonzi carnitine?
Carnitine inonzi quaternary ammonium compound inobatanidzwa mumetabolism mumhuka dzakawanda, zvinomera, uye mamwe mabhakitiriya. Mukutsigira kushandiswa kwesimba, carnitine inotakura mafuta ane mafuta akareba kupinda mumitochondria kuti iite oxidized nokuda kwekugadzirwa kwesimba risina mari, uye inobatanidzwawo mukubvisa zvigadzirwa zvemasero kubva mumasero. Tichifunga nezvemabasa ayo anokosha, carnitine inonyanya kuwanika mumasero akaita semhasuru dzomuviri nemwoyo dzinoita kuti mafuta ashandiswe semagetsi. Kazhinji vanhu, kubatanidza vanodya miriwo, vanogadzira L-carnitine yakakwana in vivo.  Carnitine iripo seimwe yema stereoisomers maviri (ma enantiomers maviri d-carnitine (S-(+-) uye l-carnitine (R-(−)-)). Zvose zviri zviviri zvinoshanda, asi l-carnitine chete ndiyo inowanika nemasikirwo kumhuka, uye d-carnitine ine chepfu sezvo ichitadzisa kushanda kwechimiro cheL. Pakupisa kwemukamuri, carnitine yakachena ipfu yakachena, uye zwitterion inogadziriswa nemvura ine chepfu yakaderera. Inobva mumaamino acids, carnitine yakatanga kubviswa munyama muna 1905, ichitungamirira kuzita rayo kubva muchiLatin, "caro/carnis" kana kuti nyama.  Vamwe vanhu vane zvirwere zvokuberekwa nazvo kana kuti zvokurapa (zvakadai sevana vanoberekwa nguva isati yakwana) havagoni kugadzira carnitine yakakwana, vachida zvokudya zvokuwedzera. Pasinei nokuwanzoshandiswa kwecarnitine pakati pevatambi kuti vavandudze kuita kwavo basa kana kuti kupora, hapana uchapupu hwakakwana hwemakiriniki hunoratidza kuti hunobatsira.
