Daim ntawv thov hauv Cov Khoom Siv Tshuaj Txhua Hnub
Amino acid surfactants muaj kev ntub dej zoo, ua npuas dej, tshuaj tua kab mob, tiv thaiv -corrosion, thiab antistatic zog. Lawv tsis yog - lom, tsis muaj mob, thiab maj mam rau ntawm daim tawv nqaij. Lawv cov khoom degradation yog cov amino acids thiab fatty acids, uas tsis muaj kev cuam tshuam ib puag ncig. Tsis tas li ntawd, lawv muaj kev sib raug zoo nrog lwm cov surfactants thiab tuaj yeem siv dav hauv cov khoom siv tshuaj pleev ib ce xws li tshuaj ntxuav ntsej muag, da dej gels, thiab tshuaj zawv plaub hau. Amino acid-raws li cov khoom siv tshuaj ntsuab niaj hnub siv cov amino acids ua cov tshuaj ntxuav tseem ceeb twb tau tsim. Piv txwv li, hauv cov tshuaj txhuam hniav rau kev saib xyuas qhov ncauj, tus neeg sawv cev foaming, fatty acyl amino acid surfactant, tuaj yeem cuam tshuam cov kab mob lactic acid uas hloov cov piam thaj mus rau hauv lactic acid, muab cov txiaj ntsig zoo ntxuav thiab ua pa tsw qab. Lwm cov ntaub ntawv qhia tias ntxiv surfactants xws li potassium lauroyl glutamate thiab sodium cocoyl glutamate los pleev xim rau cov tshuaj detergent tsis tsuas yog zam cov tawv nqaij khaus tab sis kuj tswj cov kev ua ntawm enzymes hauv cov tshuaj ntxuav tes.
Thaum yuav khoom txhua hnub, koj tuaj yeem tshawb xyuas cov npe khoom los txiav txim siab seb cov tshuaj ntxuav tes puas yog amino acid-raws li. Piv txwv li, muaj ob hom tshuaj ntxuav ntsej muag ntawm lub khw: xab npum-raws li thiab amino acid-surfactant-raws li. Qhov sib txawv tshaj plaws yog cov xab npum- cov tshuaj ntxuav lub ntsej muag muaj pH siab dua, yog alkaline, muaj zog degreasing nyhuv, thiab tej zaum yuav ua rau daim tawv nqaij nruj tom qab ntxuav. Lawv cov khoom xyaw yog fatty acids thiab alkaline agents, xws li lauric acid + potassium hydroxide. Amino acid{10}}cov tshuaj ntxuav lub ntsej muag tuaj yeem yog lauroyl glycinate.
Kev siv hauv biomedicine
Amino acid surfactants kuj tau siv rau hauv thaj chaw ntawm biology thiab tshuaj nyob rau hauv xyoo tas los no thiab tau ua tiav kev loj hlob sai. Piv txwv li, N-acyl amino acid surfactants tuaj yeem siv los txhim kho cov solubility ntawm cov vitamin E hauv dej, txhim kho lub peev xwm nqus ntawm tib neeg lub cev, thiab maj mam thiab tsis- khaus; lawv kuj tuaj yeem siv tau sai thiab nyab xeeb rho tawm RNA los ntawm tib neeg cov ntshav, tsiaj txhu thiab cov nroj tsuag hlwb, thiab cov kab mob, thiab kom muaj nuj nqis rho DNA, thiab lwm yam.; lawv kuj muaj qee yam kev siv hauv immunology. Acyl amino acid / peptide vesicles kuj tseem siv tau los ua cov neeg nqa tshuaj thiab rau kev npaj cov liposomes ua haujlwm nrog lipopeptide ligands; anionic amino acid surfactants tuaj yeem siv los khaws cov tshuaj hydrophilic hauv daim tawv nqaij thiab txhim kho permeability ntawm daim tawv nqaij, thiab xav tias yuav dhau los ua tus neeg saib xyuas hauv zos rau daim tawv nqaij [8]. Amino acid-raws li gemini surfactants tau pom cov lus cog tseg tshwj xeeb uas yog cov muaj peev xwm thauj khoom bioactive molecules, thiab tau muaj qee qhov kev tshawb fawb txog polycationic gemini surfactants thiab spermine gemini surfactants ua cov neeg ua haujlwm zoo hauv kev xa cov noob [8]. Nagasaka et al. [9] tsis ntev los no tau kawm txog tus kheej- cov txheej txheem ua kom muaj zog ntawm hydrophilic amino acid (histidine) thiab hydrophobic aldehyde (octanal): cov roj droplet system spontaneously tsim cov amino acid{13}}raws li surfactants, uas tom qab ntawd ua rau tus kheej -propelling ntawm cov tee dej. Qhov system no yog ib qho kev ua haujlwm uas muaj peev xwm tsim tau nws tus kheej propulsion roj thiab tuaj yeem siv los ua cov qauv kev xav ntawm cov cell metabolism. Xws li tus kheej- tsav lub tshuab ntawm cov amino acid{18}}raws li surfactants kuj tseem yuav tsum tau siv rau hauv ntau qhov chaw.
Kev siv hauv cov khoom noj
Kev nyab xeeb thiab biocompatibility ntawm cov amino acid-raws li surfactants ua tau raws li kev nyab xeeb ntawm kev lag luam zaub mov. Piv txwv li, amino acid esters tuaj yeem hloov cov amino acids raws li cov khoom noj ntxiv, uas tuaj yeem hloov cov saj thiab tsw ntawm cov zaub mov, ua kom lub txee lub neej ntawm cov zaub mov, thiab txhim kho cov khoom noj khoom haus ntawm cov khoom noj [4]. Cov me me ntawm N-acyl amino acid surfactants, siv los ua cov khoom noj khoom haus ntxiv, tuaj yeem tiv thaiv cov khoom qab zib xws li khoom qab zib, zaub roj, thiab cocoa hmoov los ntawm kev khiav tawm, tiv thaiv kev loj hlob ntawm -flavors, thiab kuj ua raws li kev khaws cia. Lawv tuaj yeem cuam tshuam cov fermentation ntawm cov tshuaj acidic thiab tiv thaiv lawv cov residue ntawm cov hniav lwj, yog li tiv thaiv cov kua qaub yaig. Tsis tas li ntawd, cov amino acid surfactants muaj anti-fogging thiab antistatic zog, ua rau lawv haum rau siv nyob rau hauv yas films rau ntim zaub mov.
