Mushonga wemakemikari we spermidine ndeye C7H19N3, iyo ine rimwe boka reamine (NH) uye maviri amino mapoka (NH2). Yayo molecular formula inoratidzwa pazasi, ndeye crystal isina ruvara inoonekera. Iyo kemikari chimiro chespermidine ine matatu maatomu enitrogen, izvo zvinoita kuti ive neimwe kemikari kuita uye biological chiitiko.

Spermidine inowanikwa mune zvakawanda zvekudya, kunyanya muhuwandu hwepamusoro mumakumbo (zvakadai sesoya), zviyo zvakakwana, zvokudya zvakaviriswa (zvakadai sechizi), howa, nemimwe michero (yakadai semichero yecitrus). Muviri unogadzirawo spermidine pachayo, kunyanya muchiropa, itsvo uye ura hudiki. Zvisinei, huwandu hwespermidine hunogadzirwa nemuviri wemunhu hunokanganiswa nezera, kudya, intestinal microbiota uye genetic factor, uye huwandu hwekugadzirwa kwemuviri wemunhu hunotanga kuderera mushure memakore makumi matatu, uye kuderera kunonyanya kuoneka mushure memakore makumi mana.

Spermidine ine anti-oxidation (yakajeka mahara radicals), anti-kuchembera (autophagy, kuchenesa senescent masero), kunatsiridza hutano hwekubereka (kunyanya kuvandudza mavhaivha, kurebesa zera rekubereka) uye kudzivirira moyo uye cerebrovascular, nezvimwewo, yave chigadzirwa chenyeredzi mumunda wekurwisa kukwegura.

?

Spermidine ine maitiro maviri ekubvisa chirimwa uye biological fermentation, zvigadzirwa zvespermidine pamusika zvinonyanya kutorwa kubva mupunga kana gorosi germ seyakagadzirwa, uye mutengo we98% yakachena zvigadzirwa wakakwira se7000 yuan / kg.

Biosynthesis: synthesizing spermidine ne homoserine uye putrescine (butylenediamine) se substrate, dehydrogenating homoserine kune aspartate hemialdehyde uye NADH ine homoserine dehydrogenase, synthesizing aspartate hemialdehyde uye putrescine kune carboxyglarine neNADH se coenzyme, uye kubudirira patsva. Pakupedzisira, arginine decarboxylase decarboxylated arginine kugadzira arginine. Iko kusanganiswa kwespermidine mune mhinduro mhinduro inogona kunge iri 13g/L.

Parizvino, makambani ekugadzira biology emudzimba Huarui Biology, Zhongke Xinyang, Twinings Biology neShanghai ergothione nemamwe makambani ari kusundira zvigadzirwa zvekugadzira biology spermidine, avo vanogona kupedzisira vatungamira mukusimudzira maindasitiri uye vova ivo vanonyanya kuwanikwa ngatimirirei tione.
