?O ke kumu kemika o ka spermidine ?o C7H19N3, aia i loko o ho?okahi pū?ulu amine (NH) a me ?elua pū?ulu amino (NH2). Hō?ike ?ia kona ?ano molekala ma lalo nei, nona ka aniani aniani ?a?ole waiho?olu?u. Aia i loko o ka hale kemika o ka spermidine ?ekolu mau ?ātoma nitrogen, kahi e loa?a ai iā ia kekahi hana kemika a me ka hana biological.

Loa?a ka Spermidine i nā mea?ai he nui, ?oi aku ka nui o nā legumes (e like me ka soybeans), nā kī?aha piha, nā mea?ai fermented (e like me ka cheese), nā halo, a me kekahi mau hua (e like me nā hua citrus). Ho?ohui pū ke kino i ka spermidine pono?ī, ?oi loa i loko o ke ake, nā pu?upa?a a me ka ?ōpū li?ili?i. Eia na?e, ?o ka nui o ka spermidine i hana ?ia e ke kino o ke kanaka e pili ana i ka makahiki, ka ?ai, ka microbiota intestinal a me nā kumu genetic, a ho?omaka ka emi ?ana o ka synthesis pono?ī o ke kanaka ma hope o ka makahiki 30, a ?ike ?ia ka emi ?ana ma hope o 40 mau makahiki.

?

Spermidine he anti-oxidation (ho?oma?ema?e free radicals), anti-aging (autophagy, ho?oma?ema?e senescent cell), ho?omaika?i i ke olakino hānau (?oi aku ka ho?omaika?i ?ana i nā ovaries, ho?olō?ihi i ka makahiki hānau) a pale i ka cardiovascular a me ka cerebrovascular, etc., ua lilo i huahana hōkū i ke kahua o ka anti-aging.

?

He ?elua ka?ina hana o ka Spermidine no ka ?ili ?ana i nā mea kanu a me ka fermentation biological, ?o nā huahana spermidine ma ka mākeke ka mea nui i lawe ?ia mai ka laiki a i ?ole ka hua hua palaoa e like me nā mea maka, a ?o ke kumukū?ai o 98% nā huahana ma?ema?e e like me 7000 yuan / kg.

?

Biosynthesis: synthesizing spermidine me ka homoserine a me ka putrescine (butylenediamine) ma ke ?ano he substrate, dehydrogenating homoserine e aspartate hemialdehyde a me NADH me ka homoserine dehydrogenase, synthesizing aspartate hemialdehyde a putrescine i ka carboxyglarine me NADH a me NADH e like me ka coenzygeneration. ?O ka hope, arginine decarboxylase decarboxylated arginine e hana i ka arginine. ?O ka ?ike ?ana o ka spermidine i ka hopena hopena hiki ke ma kahi o 13g/L.

?

I kēia manawa, ?o nā hui biology synthetic home Huarui Biology, Zhongke Xinyang, Twinings Biology a me Shanghai ergothione a me nā ?oihana ?ē a?e e ho?oikaika nei i nā huahana spermidine biology synthetic, hiki iā lākou ke alaka?i i ka ?oihana a lilo i mea ho?olako nui e kali mākou a ?ike.
