Sericin Powder yog dab tsi?

Sericin yog lub ntuj macromolecular protein qhwv nyob rau saum npoo ntawm silk fiber. Nws yog tsuas yog secreted los ntawm cov kab mob ntawm cov kab mob silkworms thiab yog ib qho ntawm cov proteins tseem ceeb uas ua rau cov kab mob silkworm cocoons. Sericin yog dav siv nyob rau hauv lub nraub qaum ntawm fabrics vim nws cov dej solubility zoo, txhawb cell adhesion thiab proliferation kev ua, txo immunogenicity, thiab tshwj xeeb nyob rau hauv situ fluorescence, antioxidant kev ua si thiab tyrosinase inhibition. Ua tiav cov txheej txheem, tshuaj pleev ib ce, thiab zaub mov, tshuaj, thiab cov khoom siv biomaterials.

Qauv

Sericin yog cov dej-soluble globular protein, thiab nws qhov hnyav molecular hauv kev daws yog cuam tshuam los ntawm kub, pH, thiab lwm yam. Nws muaj 18 hom amino acid residues, ntawm cov amino acid tseem ceeb residues yog serine (Ser), aspartic acid ( Asp), thiab glycine (Gly), thiab lawv cov ntsiab lus yog kwv yees li 33 feem pua , 20 feem pua thiab 14 feem pua , feem. Amino acid residues muaj ib tug loj tus naj npawb ntawm cov muaj zog polar pawg xws li hydroxyl, carboxyl, thiab amino pawg, thiab cov polar side saw amino acids nyob rau hauv sericin account rau ntau tshaj 70 feem pua.

Thaum cov hydrogen ions thiab hydroxide ions ua ke ntawm cov protein mus txog qhov sib npaug thiab cov nqi ntawm cov protein yog xoom, pH ntawm cov tshuaj nyob rau lub sijhawm no yog qhov isoelectric point ntawm cov protein. Thaum pH tus nqi ntawm cov tshuaj yog tsawg, sericin muaj nyob rau hauv daim ntawv ntawm zoo ions, thiab thaum lub pH tus nqi ntawm cov tshuaj yog siab, sericin muaj nyob rau hauv daim ntawv ntawm tsis zoo ions. Sericin yog globular protein, nws cov polypeptide saw yog nruj nreem folded, hydrophobic amino acid sab saw nyob rau hauv lub molecule, thiab cov hydrophilic amino acid sab saw yog raug rau cov dej hnyav sab nraum, yog li cov globular protein muaj zoo solubility nyob rau hauv dej hnyav. . Txawm li cas los xij, qhov hnyav molecular ntawm sericin muaj kev cuam tshuam zoo rau nws cov solubility. Me me molecular sericin tuaj yeem yaj hauv dej txias, thiab loj molecular sericin tuaj yeem yaj hauv dej kub. Sericin yog lub ntuj biopolymer uas muaj qhov hnyav molecular, yog li qhov loj me ntawm sericin feem ntau yog nyob nruab nrab ntawm 1 thiab 100nm, uas belongs rau ntau yam ntawm cov khoom siv colloidal, yog li cov tshuaj sericin tseem yuav qhia kev lim ntshav, coagulation, gelation, thiab lwm yam. colloidal daws xws li gelation thiab peptization.

Cov txiaj ntsig yog dab tsi?

Moisturizing thiab Humidity Control Function

Sericin muaj cov khoom xyaw zoo sib xws rau lub ntuj moisturizing yam muaj nyob rau hauv tib neeg lub cev, yog li nws tsis tsuas moisturizes tab sis kuj tswj cov dej noo nyob rau hauv daim tawv nqaij, tso cai rau cov tawv nqaij kom noo noo thiab elasticity. Nyob rau tib lub sijhawm, nws hydrolyzate kuj yog ib qho antioxidant ntuj. Lub peev xwm los inhibit oxidation zoo ib yam li VC.

Daim tawv nqaij anti-inflammatory nyhuv

Cov dej-soluble sericin muaj txiaj ntsig zoo rau qee cov kab mob ntawm daim tawv nqaij thiab yog ib qho tshuaj zoo rau daim tawv nqaij mob. Nws tuaj yeem txo qhov mob thiab ua lub luag haujlwm zoo hauv cov tawv nqaij laus thiab tsis muaj zog elasticity.

tiv thaiv tshav ntuj

Silk fibroin yog nplua nuj nyob rau hauv tyrosine, tryptophan thiab phenylalanine, zoo li sericin. Lawv tuaj yeem nqus tau cov kab hluav taws xob ultraviolet, tiv thaiv ultraviolet rays los ntawm kev puas tsuaj thiab kev laus ntawm daim tawv nqaij, thiab yog cov khoom xyaw zoo heev rau tshuaj pleev thaiv hnub ~

Daim ntawv thov kev taw qhia

Tshuaj pleev ib ce

Cov tawv nqaij li qub yuav tsum muaj 10 feem pua -20 feem pua ntawm cov dej noo kom ntseeg tau tias cov tawv nqaij elasticity thiab plumpness. Lub ntuj moisturizing yam nplua nuj nyob rau hauv sericin yog ib tug zoo meej cov khoom xyaw uas combines moisturizing thiab humidity tswj. Tam sim no nws tau siv dav hauv cov khoom tu tawv nqaij xws li ntxuav, tshuaj pleev, pleev, thiab tshuaj pleev.

Teb zaub mov

Cov amino acids uas muaj nyob rau hauv sericin tsis yog tsuas yog cov amino acids tseem ceeb rau tib neeg lub cev, tab sis 90 feem pua ntawm lawv tuaj yeem nqus tau ncaj qha los ntawm tib neeg lub cev. Cov amino acids sib txawv sib txawv rau cov teebmeem sib txawv. Tib lub sijhawm, ob qho no kuj yog ib qho khoom noj khoom haus uas tuaj yeem txhim kho kev nco thiab tiv thaiv kev dementia.

Lub tuam txhab kev taw qhia thiab daim ntawv pov thawj tau txais

Shaanxi Yuantai Biotechnology Co., Ltd. tau tsim nyob rau xyoo 2014, feem ntau muab cov tshuaj ntsuab rho tawm, ua haujlwm kom zoo nkauj raw cov ntaub ntawv, cov khoom siv organic, thiab lwm yam. Peb muaj peb tus kheej factories, R & D thiab pab pawg soj ntsuam zoo, thiab muaj cov xwm txheej rau kev txhim kho, ntau lawm, thiab kev ruaj ntseg zoo.
