Intshayelelo yeMveliso
I-Glycine yeyona nto ilula phakathi kwamalungu angama-20 oluhlu lwe-amino acid. Ikwabizwa ngokuba yi-aminoacetic acid. Yi-amino acid engabalulekanga emzimbeni womntu. Inamaqela asebenzayo e-acidic kunye ne-alkaline kwimolekyuli. Yi-electrolyte enamandla kwisisombululo samanzi kwaye i-polar kakhulu. Inokunyibilika okuphezulu kwi-solvents, ayinyibiliki kwi-solvents ezingezizo ze-polar, kwaye inamanqaku aphezulu okubila nokunyibilika. I-Glycine ingathatha iifom ezahlukeneyo ze-molecular ngokulungisa i-acidity kunye ne-alkaline yesisombululo samanzi. I-bond esecaleni ye-glycine yi-atom ye-hydrogen. Ekubeni i-alpha carbon yayo nayo ine-atom ye-hydrogen, i-glycine ayi-isomeric ebonakalayo. Ngenxa yokuba ii-side bonds ze-glycine zincinci kakhulu, zinokuthatha indawo ezingenako ezinye ii-amino acids, njenge-amino acid ngaphakathi kwe-collagen helix. Yikristale emhlophe okanye i-crystalline powder etyheli ekhanyayo kubushushu begumbi. Inobumnandi obukhethekileyo obunokunciphisa incasa ye-acid kunye ne-alkaline, ifihle incasa ekrakra ye-saccharin eyongezwe ekutyeni kwaye yonyuse ubumnandi. Ukuba umzimba womntu utya i-glycine eninzi, ayizukuphela nje kokuba ingafunxwa kwaye isetyenziswe ngumzimba womntu, kodwa iya kwaphula ibhalansi yokufunxwa komzimba kwee-amino acids kwaye ichaphazele ukufunxwa kwezinye ii-amino acids, nto leyo ekhokelela ekungalinganini kwezondlo kwaye ichaphazele impilo. Iziselo eziqulethe ubisi eziveliswa nge-glycine njengezinto eziphambili ezikrwada zinokuba nemiphumo emibi ekukhuleni okuqhelekileyo kunye nophuhliso lwabakwishumi elivisayo nabantwana. Ubuninzi 1.1607. Iqondo lokunyibilika 232~236℃ (ukubola). Inyibilika emanzini, ayinyibiliki kwi-ethanol kunye ne-ether. Ingasabela kwi-hydrochloric acid ukwenza i-hydrochloric acid. Ikhona kwimisipha yezinto zokuthutha ezomileyo ezikumgangatho ophantsi. Ingaveliswa yintshukumo ye-monochloroacetic acid kunye ne-ammonium hydroxide, okanye ingafunyanwa ngokuyi-hydrolysis kunye nokucocwa kwe-gelatin.
Umsebenzi weMveliso
I-Glycine isetyenziswa kakhulu njengesongezelelo sesondlo sokondla inkukhu.
Izongezo zesondlo. Zisetyenziswa kakhulu kwizinongo nezinye izinto.
Isetyenziswa kwishishini lamayeza, kuvavanyo lwe-biochemical kunye nokwenziwa kwezinto eziphilayo.
Isetyenziswa njenge-buffer, isetyenziswa ekulungiseleleni i-tissue culture media, ukuvavanya i-copper, igolide nesilivere, kwaye isetyenziswa njengeyeza ukunyanga i-myasthenia gravis kunye ne-progressive muscle atrophy, i-hyperacidity, i-chronic enteritis, i-hyperprolinemia ebantwaneni, njl.njl. isifo.
Nyanga i-myasthenia gravis kunye nokuwohloka kwemisipha okuqhubekayo; nyanga i-hyperlipidemia kunye ne-enteritis engapheliyo (idla ngokudityaniswa ne-antacids); zidityaniswe ne-aspirin kunokunciphisa ukurhawuzelelwa sisisu; nyanga i-hyperprolinemia ebantwaneni; njenge-Velisa umthombo we-nitrogen wee-amino acids ezingezizo ezibalulekileyo kwaye wongeze kwi-mixed amino acid injection.
Isicelo seMveliso
Izongezo zesondlo. Zisetyenziswa kakhulu kwizinongo, amayeza, izongezo zesondlo zokutya kwenkukhu, kwaye zikwasetyenziswa ekuveliseni izichumisi zeekhemikhali kunye nezibulali zinambuzane.
