I-Asparagine [uphawu lwe-Asn noma i-N] iwukhiye we-α-amino acid esetshenziswa ku-biosynthesis yamaprotheni.Iqukethe iqembu le-α-amino kanye neqembu le-α-carboxylic acid kanye ne-carboxamide ye-side chain.Ihlukaniswa njenge-polar [ku-pH ye-physiological], i-aliphatic amino acid.Ayibalulekile kubantu, futhi ingangena ku-de novo synthesis ngaphakathi emzimbeni womuntu.Kusukela kusici sekhodi yofuzo ngesikhathi sokuhlanganiswa kwamaprotheni, ifakwe ikhodi ngama-codon AAU ne-AAC.I-L-Asparagine iwukuphuma okungashajwa kwe-aspartate.
Ukusetshenziswa kwe-L-Asparagine Anhydrous (Asn Anhydrous) (CAS: 70-47-3)
1. Emithi, i-L-Asparagine ingasetshenziswa ukwelapha isifo senhliziyo, isifo sesibindi, umfutho wegazi ophezulu, ngomphumela wokuvimbela nokubuyisela ukukhathala.Kanye nezinhlobonhlobo zama-amino acid, ingenziwa ibe ukumnika kwe-amino acid, esetshenziswa njenge-ammonia antidote, umgqugquzeli wokusebenza kwesibindi, i-ejenti yokutakula ukukhathala.
I-L-Asparagine isidakamizwa esisetshenziselwa ukwehlisa umfutho wegazi, i-bronchus enwebekayo (isifuba somoya), isilonda se-peptic kanye nokungasebenzi kahle kwesisu.Ukwehlisa umfutho wegazi, i-bronchus enwebekayo (isifuba somoya), isilonda esilwa ne-peptic kanye nokungasebenzi kahle kwesisu.Isetshenziselwa isiko le-microbial, ukwelashwa kwendle ye-acrylonitrile, njll.
2. Embonini yokudla, i-L-Asparagine iyisengezo esihle sokudla okunomsoco, esinezelwa ezinhlobonhlobo zeziphuzo ezipholile;Kuphinde kube yimpahla eluhlaza eyinhloko ye-sweet monosodium glutamate (aspartame)-aspartate phenylalanine methyl ester.
I-Asparagine inomsebenzi omuhle wokuveza okusha nokulondolozwa.I-L-Asparagine isetshenziswa kabanzi njengokulungiswa komuthi noma ukuveza okusha nesibulala-magciwane emsebenzini wokudla, futhi ingangena esikhundleni se-monosodium glutamate.
3. Embonini yamakhemikhali, i-L-Asparagine ingasetshenziswa njengezinto ezingavuthiwe ze-synthetic resin nanjengesengezo sokudla okunomsoco sezimonyo.
