Imiti ya spermidine ni C7H19N3, igizwe nitsinda rimwe rya amine (NH) hamwe nitsinda rya amino (NH2). Inzira ya molekulari yayo irerekanwa hepfo, ijyanye na kirisiti itagira ibara. Imiterere yimiti ya spermidine irimo atome eshatu za azote, bigatuma igira ibikorwa byimiti nibikorwa byibinyabuzima.

Spermidine iboneka mu biribwa byinshi, cyane cyane mu binyamisogwe byinshi (nka soya), ibinyampeke byose, ibiryo byasembuwe (nka foromaje), ibihumyo, n'imbuto zimwe na zimwe (nk'imbuto za citrusi). Umubiri kandi uhindura intanga ngabo ubwazo, cyane cyane mu mwijima, impyiko no mu mara mato. Nyamara, ingano ya spermidine ikorwa numubiri wumuntu igira ingaruka kumyaka, indyo, microbiota yo munda hamwe na genetique, kandi ingano yimikorere yumubiri wumuntu itangira kugabanuka nyuma yimyaka 30, kandi kugabanuka kugaragara cyane nyuma yimyaka 40.

Spermidine ifite anti-okiside (radicals yubusa isobanutse), kurwanya gusaza (autophagy, gusukura ingirabuzimafatizo za senescent), kuzamura ubuzima bwimyororokere (cyane cyane kunoza intanga ngore, kumara imyaka yimyororokere) no kurinda umutima nimiyoboro yubwonko nubwonko, nibindi, byahindutse ibicuruzwa byinyenyeri mubijyanye no gusaza.

Spermidine ifite uburyo bubiri bwo kuvoma ibihingwa no gusembura ibinyabuzima, ibicuruzwa bya spermidine ku isoko bikurwa cyane cyane mumuceri cyangwa mikorobe y ingano nkibikoresho fatizo, kandi igiciro cyibicuruzwa 98% byuzuye bingana na 7000 yuan / kg.

Biosynthesis: guhuza spermidine hamwe na homoserine na putrescine (butylenediamine) nka substrate, dehydrogenating homoserine to aspartate hemialdehyde na NADH hamwe na homoserine dehydrogenase, guhuza aspartate hemialdehyde na putrescine kuri carboxyglarine hamwe na NADH nka coenzyme. Hanyuma, arginine decarboxylase decarboxylated arginine kugirango itange arginine. Ubwinshi bwa spermidine mugisubizo cya reaction irashobora kuba 13g / L.

Kugeza ubu, amasosiyete y’ibinyabuzima yo mu gihugu Huarui Biology, Zhongke Xinyang, Twinings Biology na Shanghai ergothione hamwe n’andi masosiyete arimo asunika ibicuruzwa by’intanga ngengabuzima, amaherezo bishobora gufata iyambere mu nganda kandi bigahinduka isoko nyamukuru reka dutegereze turebe.
