Upfu hweProline
Proline (yakapfupikiswa sePro kana P), ine fomura yemakemikari C5H9NO2 uye huremu hwemamorekuru hwe115.13, i cyclic sub amino acid. α- MaAmino acid, asina kwaakarerekera, ane point ye isoelectric ye6.30, ane solubility yakakura mumvura kupfuura chero imwe amino acid, uye anogona kunyungudika inosvika 162g mu 100g yemvura pa25 ℃. Zviri nyore kunyungudika asi hazvisi nyore kuumba crystallize, ine kuravira kunotapira. Kupisa pamwe chete ne ninhydrin solution kunogadzira makemikari eyero. Kana yangopinda mu peptide chain, hydroxylation inogona kuitika, zvichikonzera kuumbwa kwe 4-hydroxyproline, inova chinhu chakakosha che collagen yemhuka. Hydroxyproline inowanikwawo mumapuroteni akasiyana-siyana emiti, kunyanya ane chekuita nekuumbwa kwemadziro esero. Zvirimwa zvinowanzo sangana nekuunganidzwa kwakakosha kweproline pasi pemamiriro akasiyana-siyana asina kunaka akadai sekusanaya kwemvura, tembiricha yakakwira, tembiricha yakaderera, uye munyu. Inoshandiswa zvakanyanya muminda yekiriniki, biomaterial, maindasitiri, nedzimwe nzvimbo.
Kune marudzi matatu eproline:DL proline, L-proline, uye D-proline. Proline inowanzonzi L-proline, amino acid inowanikwa zvakasikwa. Pakupisa kwemumba, chigadzirwa ichi chakaita sekristaro yekoramu. Chinoora nekukurumidza kana chapiswa kusvika 215-220 ℃. Chinonyungudika mumvura inopisa uye ethanol. Chinotapira zvishoma uye chinonyungudika. Kupatsanurwa mualkaline solution. [α] D25-86.5 ° (mvura), -60.4 ° (5N hydrochloric acid). Chinopararira mumapuroteni akasiyana-siyana. Amino acid ine huwandu huri pakati nepakati mu plankton yegungwa; Inowanikwawo mumvura yegungwa, particulate matter, uye marine sediments.
Proline iamino acid isingakoshi mumuviri wemunhu.
Basa nechinangwa
Kushandiswa muindasitiri yemishonga
Mishonga yeAmino acid. Imwe yezvinhu zvekushandisa pakuisa amino acid yakawanda. Inoshandiswa kuwedzera mapuroteni mushure mekushaya chikafu chakakwana, kushomeka kweprotein, zvirwere zvakakomba zvemudumbu, kutsva, uye kuvhiyiwa. Hapana migumisiro yakaipa iri pachena.
Migumisiro yemuviri
Muzvinhu zvipenyu, proline haisi chinhu chakanaka che osmoregulation chete, asiwo inoshanda sechinodzivirira membrane nema enzymes, pamwe ne free radical scavenger, nokudaro ichidzivirira kukura kwemiti pasi pekumanikidzwa kwe osmotic. Pakuunganidza chimwe chinhu chakakosha che osmoregulation muma vacuoles mu potassium ion zvipenyu zvipenyu, proline inogonawo kuita basa rekutonga mu cytoplasmic osmotic balance.
Zvishandiso zvemaindasitiri
Muindasitiri yekugadzira zvinhu, proline inogona kutora chikamu mukukonzera kusawirirana uye inoshanda senzira yekuwedzera hydrogenation, polymerization, uye nzira dzekuchinjana mvura. Kana ikashandiswa senzira yekuchinjana kwakadaro, ine simba guru uye ine stereospecificity yakanaka.
Mashandisirwo mune dzimwe nzvimbo
1. Proline nezvimwe zvinobva mairi zvinowanzo shandiswa senzira dzinoita kuti zvinhu zvienderane nezvinodiwa nemuviri, nekudzikira kweCBS uye kukanganiswa kweproline ne aldol.
2. Panguva yekubika, mapuroteni ane proline yakawanda inobatanidzwa nema polyphenols, ayo anogona kukonzera hutsi (turbidity).
3. Zvinhu zvisina kugadzirwa zvekugadzira zvinodzivisa gallstone ester.
4. Zvinonhuwirira, izvo zvinosangana neshuga nekupisa pamwe chete kuti zvigadzire mapoka emaamino hydrogen, zvinogona kugadzira zvinhu zvine hwema hwakakosha.
1. Anopfuura makore gumi eruzivo neISO certification,
2. Fekitori yekusanganisa kuravira nekutapira, Tianjia Own Brands,
3. Tsvagiridzo pamusoro peruzivo rwemusika & mafambiro ekutevera,
4. Kuendesa Nenguva Yakakodzera & Kukwidziridzwa Kwemasheya pazvigadzirwa zvinopisa zvinoda,
5. Yakavimbika & Tevedzera zvakanyanya mutoro wechibvumirano & mushure mekutengesa,
6. Nyanzvi paInternational Logistic Service, magwaro emutemo & maitiro ekuongorora ebato rechitatu.
