Ọkwa ịchọ mma mmiri silk peptide ntụ ntụ soluble
Nkọwa ngwaahịa
Silk peptide bụ ụdị ihe polypeptide na-agbaze mmiri site na mmebi nke protein fibroin silk, nke ịdị arọ ya dị n'etiti 500 na 10000, nke bụ ntụ ntụ na-acha ọcha na mmiri dị mma, mmeghachi omume ninhydrin dị mma.

- Ọ nwere omume nke moisturize eke, na-edozi anụ ahụ na ịkwalite ọnya anụ ahụ.
- Dị ka ụlọ ọgwụ gosipụtara, peptide silk nwere mmetụta ọgwụgwọ dị mma na nhịahụ, dermatitis, itching, na iwepụ chloasma. Pentide silk adịghị ewe iwe ma nwee ike mee ka ọnya gwọọ ngwa ngwa. peptide silk nwekwara ike igbochi akpụkpọ ahụ site na mbuze na mmebi nke kemịkalụ dị ka uzuzu, mkpuchi, acid na alkali. Ya mere, akpụkpọ anụ ahụ na-eji ngwaahịa nlekọta anụ ahụ bara ụba na peptide silk nwere ike nweta mmetụta ịchọ mma ma gbochie ọtụtụ ọrịa anụ ahụ.
- Ọrụ nlekọta ntutu pụtara nke ukwuu
- Ọrụ nlekọta ntutu isi nke peptide silk na-egosipụtakarị na absorptivity, absorbability, ihe na-emepụta ihe nkiri, iru mmiri na idebe mmiri na ntutu.
- E jiri ya tụnyere protein hydrolyzate ndị ọzọ (collagen, protein collagen, protein gelatin, wdg), ihe kachasị mma nke peptide silk bụ na ọ bara ụba na nri na-edozi ahụ ma nwee ike ịmegharị ya ngwa ngwa n'ime ntutu. Ntinye peptide silk na akpụkpọ ahụ na ntutu na-adabere na njedebe. Mmụba nke mkpokọta silk peptide ga-eme ka ọnụọgụ nke peptide silk silk site na ntutu dabara adaba. N'ihe gbasara ntutu isi mebiri emebi, ọ nwere nnukwu ntinye uche na ikike adsorbing, nke n'aka nke ya silk peptide nwere nrụzi doro anya na nchebe na ntutu.
- The peptide silk nke molekụla ịdị arọ dị n'etiti 500 na 2,000 nwere ọmarịcha ihe nkiri na-emepụta ihe na ntutu isi, na ihe nkiri ahụ nwere ihe na-egbuke egbuke pụrụ iche, ebe ntutu na-adị mma ma na-agbanwe. X-ray diffraction usoro na-egosi na akpụkpọ ahụ e kpụrụ na silk peptide bụ β ụdị crystallization, na akpụkpọ ahụ e mere na silk peptide na ntutu nwere ike ime ka elasticity na luster ntutu. Ka ọ dị ugbu a, a pụkwara iji ya dị ka ntutu isi. N'ịtụle peptide silk na PVP, collagen peptides, ngwọta starchy, n'okpuru ọnọdụ iru mmiri nke 80% RH, iji silk peptide dị ka ntutu isi nwere ike ime ka ntutu dị mma ruo ogologo oge.
- Mgbe ịnwụsịrị ụfọdụ mmiri, ntutu ga-akpọnwụ, na-enwe ike imebi na ịpụ ma kewaa n'otu oge ahụ. Ihe mkpuchi nke peptide silk kpụrụ n'elu ntutu nwere ike igbochi mmiri ịpụpụ oke. Dị ka ihe na-eme ka mmiri dị n'okike, ọ nwekwara ike ịhazigharị mmiri nke obere oghere n'elu ntutu isi, na-eme ka ntutu dị nro ma dị nro.
