I-chemical formula ye-spermidine yi-C7H19N3, equkethe iqela elilodwa le-amine (NH) kunye namaqela amabini e-amino (NH2). Ifomula yayo yeemolekyuli iboniswe ngezantsi, iyeyekristale e transparent engenambala. Ulwakhiwo lwekhemikhali ye-spermidine lune-athomu ezintathu ze-nitrogen, ezenza zibe nomsebenzi othile wekhemikhali kunye nomsebenzi webhayoloji.

I-Spermidine ifumaneka kukutya okuninzi, ngakumbi kwiimali eziphezulu kwiimbotyi (ezifana neembotyi zesoya), ukutya okuziinkozo, ukutya okuvundisiweyo (okufana noshizi), amakhowa, kunye nezinye iziqhamo (ezifana neziqhamo zesitrasi). Umzimba uphinde wenze i-spermidine ngokwayo, ngakumbi kwisibindi, izintso kunye namathumbu amancinci. Nangona kunjalo, isixa se-spermidine esiveliswa ngumzimba womntu sichatshazelwa bubudala, ukutya, i-intestinal microbiota kunye nezinto zemfuza, kunye nomthamo we-synthesis yomzimba womntu uqala ukuhla emva kweminyaka engama-30, kwaye ukwehla kubonakala ngakumbi emva kweminyaka engama-40.

I-Spermidine ine-anti-oxidation (i-radicals ecacileyo yamahhala), i-anti-aging (i-autophagy, ihlambulule iiseli ze-senescent), iphucula impilo yokuzala (ngokukodwa ukuphucula ama-ovari, ukwandisa ixesha lokuzala) kunye nokukhusela i-cardiovascular and cerebrovascular, njl., ibe yimveliso yinkwenkwezi kwintsimi yokuchasana nokuguga.

I-Spermidine ineenkqubo ezimbini zokutsalwa kwezityalo kunye ne-biological fermentation, iimveliso ze-spermidine kwimarike zikhutshwa ikakhulu kwirayisi okanye kwintsholongwane yengqolowa njengezinto ezibonakalayo, kwaye ixabiso le-98% yeemveliso ezicocekileyo liphezulu njenge-7000 yuan / kg.

I-Biosynthesis: ukudibanisa i-spermidine kunye ne-homoserine kunye ne-purescine (i-butylenediamine) njenge-substrate, i-dehydrogenating homoserine kwi-aspartate hemialdehyde kunye ne-NADH ene-homoserine dehydrogenase, ukudibanisa i-aspartate hemialdehyde kunye ne-purescine kwi-carboxyglarine kunye ne-NADH njenge-coenzyme, kunye nokuphumelela kwakhona kwi-coenzyme. Ekugqibeleni, i-arginine decarboxylase decarboxylated arginine ukuvelisa i-arginine. Ukuxinwa kwe-spermidine kwisisombululo sokuphendula kunokuba malunga ne-13g / L.

Okwangoku, iinkampani zasekhaya zokwenziwa kwebhayoloji iHuarui Biology, iZhongke Xinyang, iTwinings Biology kunye neShanghai ergothione kunye nezinye iinkampani zityhala imveliso yebhayoloji yokwenziwa kwespermidine, ezinokuthi ekugqibeleni zikhokele kushishino kwaye zibe lubonelelo oluphambili masilinde sibone.
