Gịnị mere selenium organic ji dị mma karịa selenium inorganic?
1. Dịka ihe mgbakwunye mpụga, nnweta nke selenium cysteine (SeCys) adịghị elu karịa nke sodium selenite. (Deagen et al., 1987, JNut.)
2. Anụmanụ enweghị ike imepụta selenoproteins ozugbo site na SeCys mpụga.
3. Ojiji SeCys dị irè n'ime anụmanụ na-enweta kpamkpam site na mgbanwe na njikọta nke selenium n'ụzọ metabolic na n'ime sel.
4. Enwere ike inweta ọdọ mmiri selenium eji echekwa selenium n'ime anụmanụ naanị site na itinye usoro njikọta nke protein nwere selenium n'ụdị SeMet kama molekul methionine, mana SeCys enweghị ike iji ụzọ njikọta a.
Ụzọ nnabata nke selenomethionine
A na-amịkọrọ ya n'otu ụzọ ahụ e si amịkọrọ methionine, nke na-abanye n'ime ọbara site na sistemụ sodium pumping dị na duodenum. Ntinye ahụ anaghị emetụta mmịpụta ahụ. Ebe ọ bụ na methionine bụ amino acid dị mkpa, a na-amịkọrọ ya nke ukwuu.
Ọrụ bayoloji nke selenomethionine
1. Ọrụ Antioxidant: Selenium bụ ebe GPx na-arụ ọrụ nke ọma, a na-ejikwa GPx na thioredoxin reductase (TrxR) arụ ọrụ antioxidant ya. Ọrụ Antioxidant bụ isi ọrụ nke selenium, ọrụ ndị ọzọ dị ndụ dabere na nke a.
2. Nkwalite uto: Ọtụtụ nnyocha egosila na itinye selenium organic ma ọ bụ selenium inorganic na nri nwere ike ime ka uto nke anụ ọkụkọ, ezi, anụ ehi ma ọ bụ azụ dịkwuo mma, dịka ibelata oke nri na anụ na ịbawanye ibu kwa ụbọchị.
3. Mmeziwanye arụmọrụ ọmụmụ: Nnyocha egosila na selenium nwere ike ime ka mmegharị nke sperm na ọnụọgụ sperm dị mma, ebe enweghị selenium nwere ike ime ka ọnụego mmebi nke sperm dịkwuo elu; Itinye selenium na nri nwere ike ime ka ọnụego fatịlaịza nke swabs dịkwuo elu, mee ka ọnụọgụ nke ihe mkpofu dịkwuo elu, mee ka ọnụego mmepụta àkwá dịkwuo elu, mee ka ọkwa mmepụta àkwá dịkwuo elu, melite mma nke shei àkwá ma mee ka ibu àkwá dịkwuo elu.
4. Meziwanye mma anụ: Oxidation lipid bụ isi ihe na-eme ka mma anụ ghara ịdị mma, ọrụ antioxidant selenium bụ isi ihe na-eme ka mma anụ dịkwuo mma.
5. Ịkwụsị nsị: Ọmụmụ ihe egosila na selenium nwere ike igbochi ma belata mmetụta ọjọọ nke lead, cadmium, arsenic, mercury na ihe ndị ọzọ na-emerụ ahụ, fluoride na aflatoxin.
6. Ọrụ ndị ọzọ: Na mgbakwunye, selenium na-arụ ọrụ dị mkpa na mgbochi ọrịa, itinye selenium, mmepụta homonụ, ọrụ enzyme nri, wdg.
