Ectoine, ogama lakhe lekhemikhali yi-tetrahydromethylpyrimidine carboxylic acid/tetrahydropyrimidine, i-amino acid derivative. Umthombo original i echibini ityuwa entlango yaseYiputa ukuba kwiimeko ezimandundu (amaqondo obushushu aphezulu, imbalela, radiation eyomeleleyo UV, ityuwa eliphezulu, uxinzelelo osmotic) ibhaktiriya entlango halophilic ukuvelisa icandelo lokhuselo yendalo kumaleko yangaphandle iseli. I-Ectoine inokufumaneka kwindalo kwinani elikhulu leebhaktheriya ezahlukeneyo, ezivelisa ngokuchanekileyo ngenxa yezizathu ezikhankanywe ngaphambili. Ewe kunjalo, impembelelo ekhuselayo enjalo kwiintlobo eziyivelisayo iye yabangela izifundo ezininzi malunga nokusetyenziswa kwe-ectoine ebantwini.
Izibonelelo ze-Ectoine kukhathalelo lwesikhumba:
1.Ukufuma
Esinye sezizathu zokuba kutheniEctoineinokuvumela ibhaktheriya ye-halophilic ukuba iphile kwiindawo ezigqithiseleyo kukuba inokulawula uxinzelelo lwe-osmotic.Iyinto enamandla kakhulu ye-hydrophilic. Nangona ubunzima be-molecular buncinci, bunokwenza "igobolondo ye-hydration" malunga neeseli kunye neeprotheni ngokudibanisa nama-molecule amanzi kwindawo engqongileyo, efana nefilimu ekhuselekileyo ekhuselekileyo. Ukunciphisa ilahleko yokufuma kwesikhumba.
2.Ukuphucula amandla okukhusela ulusu
Kungenxa yokubaEctoineinokudibanisa kunye neemolekyuli zamanzi ukwenza igobolondo elikhuselayo, ngoko ke ngaphezu kokuthintela ukulahleka kokufuma kwesikhumba, ingasetyenziselwa "njengodonga lwesixeko" ukukhusela ulusu ekuvuseleleni kwangaphandle kunye nomonakalo, ukondla nokuzinzisa ulusu, kwaye yomeleza ulusu Ukukwazi ukumelana nemisebe ye-ultraviolet kunye nongcoliseko.
3.Ukulungisa kunye nokuthomalalisa
Ectoinekukwaluncedo kakhulu ekulungiseni isithako, ngakumbi xa ufumana uvakalelo lwesikhumba, ukonakala komqobo, ukuqhawuka kwamaqhakuva, kunye nokubabomvu emva kokutshiswa lilanga. Ukukhetha esi sithako kunokuba nefuthe elithile elithomalalisayo. I-fragility kunye nokungahambi kakuhle kwesikhumba kuya kuphuculwa ngokuthe ngcembe.
