Heerka khatarta ah ee xanaaqa
D-Tryptophan (HD-Trp-OH) (CAS: 153-94-6) waa D-form (qaabka aan borotiinka ahayn) ee tryptophan amino acid.Amino acids iyo derivatives, oo loo isticmaalo isku dhafka peptide, loo isticmaalo sidii dhexdhexaad ah synthesis organic, dhexda farmashiyaha, cuntada lagu daro / quudinta, kabka nafaqada, reagent biochemical ama reagent kiimikaad.
Tryptophan waa mid ka mid ah 20-ka amino acids ee caadiga ah, iyo sidoo kale amino acid lagama maarmaan u ah cuntada aadanaha.Waxay ku qoran tahay xeerka hiddaha caadiga ah sida codon UGG.D-stereoisomer ayaa marmar laga helaa peptides si dabiici ah loo soo saaray (tusaale ahaan, sunta badda ee peptide contryphan).Sifada qaab dhismeedka lagu garto ee Tryptophan waa in ay ka kooban tahay koox shaqaynaysa indole.Waa amino acid lagama maarmaan ah sida lagu qeexay saamaynta koritaanka ay ku leedahay jiirka.
D-Tryptophan amino acid, sida borotiin aan falcelin lahayn, ayaa leh astaamo jireed oo gaar ah.Waxaa loo isticmaali karaa sida macaaneyaal aan nafaqo lahayn, quudin wax lagu daro, wakiilada koritaanka dhirta ee warshadaha quudinta cuntada iyo beeraha.Warshadaha dawooyinka, waxa inta badan loo isticmaalaa isku-dhafka polypeptides kala duwan, halkii L-Tryptophan peptide daroogada loogu kordhin lahaa nolosha nuska iyo yaraynta waxyeelada, laakiin ma adkaysan doonto jidhka hore, waxayna noqon doontaa inhibitor enzyme muhiim ah. .Waxa kale oo ay wanaajin kartaa difaaca jidhka, dib-u-dhacyada xasaasiyadda.Inta badan antibiyootiga peptide waxay u adkeysan kartaa bakteeriyada garaam-positive, bakteeriyada Gram-negative iyo qaar, sida Pseudomonas aeruginosa, mycobacteria, fungi, bakteeriyada, pathogens iyo unugyada burooyinka, kuwaas oo si fiican u xakameynaya oo u dilaya awoodda.
D-Tryptophan waxaa loo isticmaali karaa synthetic ee antibiyootiga semi-synthetic, taas oo farmaajolojigu door muhiim ah ka ciyaaro silsiladda dhinaca.Isku-xidhka peptide-ku waa ay adagtahay in uu noqdo fal-celis β-lactam enzyme, sidaas darteed xasillooni sare, oo leh bakteeriyada bakteeriyada ballaaran, sunta, hypoallergenic, nuugista degdega ah, uruurinta dhiigga sare ee daawada muddada dheer.
