I-chemical formula ye-spermidine yi-C7H19N3, equkethe iqembu elilodwa le-amine (NH) namaqembu amabili amino (NH2). Ifomula yayo yamangqamuzana iboniswe ngezansi, eyingxenye yekristalu ebonisa ngale engenambala. Isakhiwo samakhemikhali se-spermidine siqukethe ama-athomu amathathu e-nitrogen, okwenza kube nomsebenzi othile wamakhemikhali kanye nomsebenzi webhayoloji.

I-Spermidine itholakala ekudleni okuningi, ikakhulukazi ngamanani aphezulu ku-legumes (njengobhontshisi wesoya), okusanhlamvu, ukudla okuvutshiwe (njengoshizi), amakhowe, nezinye izithelo (njengezithelo ezisawolintshi). Umzimba uphinde uhlanganise i-spermidine ngokwayo, ikakhulukazi esibindini, ezinso namathumbu amancane. Kodwa-ke, inani le-spermidine elikhiqizwa umzimba womuntu lithinteka ngenxa yobudala, ukudla, i-microbiota yamathumbu kanye nezici zofuzo, futhi inani lokwakheka komzimba womuntu liqala ukwehla ngemva kweminyaka engama-30, futhi ukwehla kubonakala kakhulu ngemva kweminyaka engama-40.

I-Spermidine ine-anti-oxidation (i-radicals ecacile yamahhala), i-anti-aging (i-autophagy, ihlanza amangqamuzana e-senescent), ithuthukise impilo yokuzala (ikakhulukazi ithuthukise ama-ovari, ikhulise iminyaka yokuzala) futhi ivikele i-cardiovascular and cerebrovascular, njll., isibe umkhiqizo wenkanyezi emkhakheni wokulwa nokuguga.

I-Spermidine inezinqubo ezimbili zokukhishwa kwezitshalo nokuvutshelwa kwezinto eziphilayo, imikhiqizo ye-spermidine emakethe ikhishwa ikakhulukazi elayisi noma igciwane likakolweni njengezinto zokusetshenziswa, futhi intengo yemikhiqizo ehlanzekile engu-98% iphezulu njenge-7000 yuan / kg.

I-Biosynthesis: ukuhlanganiswa kwe-spermidine nge-homoserine kanye ne-purescine (butylenediamine) njenge-substrate, i-dehydrogenating homoserine ukuze ibe ne-aspartate hemialdehyde kanye ne-NADH nge-homoserine dehydrogenase, ihlanganisa i-aspartate hemialdehyde kanye ne-purescine ku-carboxyglarine nge-NADH njenge-coenzyme, nokufeza kabusha i-coenzyme. Ekugcineni, i-arginine decarboxylase decarboxylated arginine ukukhiqiza i-arginine. Ukuhlushwa kwe-spermidine kusixazululo sokusabela kungaba ngu-13g/L.

Njengamanje, izinkampani zasekhaya zokwenziwa zebhayoloji i-Huarui Biology, i-Zhongke Xinyang, i-Twinings Biology kanye ne-Shanghai ergothione nezinye izinkampani ziphusha imikhiqizo yokwenziwa ye-spermidine yebhayoloji, engagcina ihole kwezezimboni futhi ibe umphakeli ojwayelekile masilinde sibone.
