Kev ua kom zoo nkauj lo lo ntxhuav - Silk Fibroin, Silk Amino Acid, Silk Peptide thiab Sericin

Taw qhia

Silk silk (silk fibrin hmoov) yog ib hom macromolecular txhob lo lo ntxhuav fibrin nyob rau hauv cov hmoov ntawv, uas yog tsim los ntawm cov kabmob fiberrin ua kom lub siab tawg, yuav tsum tshwj xeeb cov khoom siv tes ua thiab tsoo los ntawm kev siv lub cev. Nws cov molecular hnyav ntawm yog txog 250000. Nws yog cov tsis qab, tsw, me ntsis soluble hauv dej thiab insoluble hauv cawv ether.

Dej-soluble sib xyaw amino acids, tseem hu ua Fibroin-90, uas qhov nruab nrab molecular hnyav yog txog 90, uas tau txais tom qab lub hydrolysis ntawm silk fibroin. Cov hmoov dawb los yog creamy, los yog tsaus muag daj pob tshab ua kua, ninhydrin cov tshuaj tiv thaiv yog qhov zoo.

Silk peptide yog ib hom dej-soluble polypeptide tshuaj los ntawm kev ua kom tsis haum ntawm silk fibroin protein, uas nws qhov hnyav nyhav ntawm 500 thiab 10000, uas yog hmoov dawb nrog dej zoo-solubility, ninhydrin cov tshuaj tiv thaiv yog qhov zoo.

Sericin hmoov yog qhov txheej txheem colloid protein ntim hauv txheej txheej sab nrauv. Nws yog hom hmoov daj thiab yog soluble hauv dej, uas ninhydrin cov tshuaj tiv thaiv yog qhov zoo.
