Isicelo
Iyi-amino acid ebalulekile ekukhuleni nasekukhuleni komuntu, futhi idlala indima ebalulekile ekukhuthazeni ukukhula nokuthuthukiswa kwezingane, ikakhulukazi ubuchopho bezinsana nezinye izitho ezibalulekile.Ibuye isetshenziswe kabanzi embonini yezemithi, embonini yokudla, embonini yokuhlanza kanye nokukhiqizwa kwe-agent emhlophe ye-fluorescent.Ngaphezu kwalokho, ibuye isetshenziselwe amanye ama-organic synthesis nama-reagents we-biochemical.Kuyi-amino acid ebalulekile e-sulfonated, elawula i-apoptosis kwamanye amaseli futhi ibamba iqhaza emisebenzini eminingi ye-metabolic ku-vivo.Ama-metabolites we-methionine ne-cysteine.Ingase futhi isetshenziselwe ukwelapha umkhuhlane ovamile, imfiva, i-neuralgia, i-tonsillitis, i-bronchitis, isifo samathambo kanye nobuthi bezidakamizwa.
I-Taurine i-amino acid eguqulwa isuka ku-amino acid equkethe isulfure, eyaziwa nangokuthi i-taurocholic acid, i-taurocholic acid, i-taurocholine, ne-taurocholine.I-Taurine isatshalaliswa kabanzi kuzo zonke izicubu nezitho zomzimba futhi itholakala ikakhulukazi esimweni esikhululekile ku-intertissue kanye noketshezi lwe-intracellular.Yaqala ukutholwa enyongweni yezinkunzi futhi yaqanjwa igama layo, kodwa sekuyisikhathi eside ibhekwa njenge-metabolite engasebenzi yama-amino acid anesulfure.I-Taurine iyi-amino acid enesulfure ezilwaneni, kodwa ayiyona ingxenye yamaprotheni.I-Taurine isatshalaliswa kabanzi ebuchosheni bomuntu nesilwane, inhliziyo, isibindi, izinso, i-ovary, isibeletho, izicubu zamathambo, igazi, amathe nobisi ngendlela yama-amino acid amahhala, anokugxila okuphezulu kakhulu ezicutshini ezifana ne-pineal gland, retina, pituitary. indlala kanye nezindlala ze-adrenal.Enhliziyweni yezilwane ezincelisayo, i-taurine yamahhala ihlanganisa cishe u-50% wawo wonke ama-amino acid amahhala.
I-synthesis kanye ne-metabolism
Ngokungeziwe ekudleni okuqondile kwe-taurine, isilwane singase siphinde siyi-biosynthesize esibindini.Umkhiqizo omaphakathi we-methionine kanye ne-cysteine metabolism, i-cysteinesulfinic acid, i-decarboxylated ibe yi-taurine nge-cysteinesulfinic acid decarboxylase (CSAD) futhi i-oxidized ukuze yakhe i-taurine.Ngokuphambene, i-CSAD ibhekwa njenge-enzyme enciphisa izinga le-taurine biosynthesis ezilwaneni ezincelisayo, futhi umsebenzi ophansi we-CSAD yomuntu uma uqhathaniswa nezinye izilwane ezincelisayo ungase ubangelwe amandla aphansi we-taurine synthesis nasebantwini.I-Taurine ibandakanyeka ekwakhekeni kwe-taurocholic acid kanye nokukhiqizwa kwe-hydroxyethyl sulfonic acid ngemuva kwe-catabolism emzimbeni.Isidingo se-taurine sincike kumthamo wokubopha i-bile acid kanye nokuqukethwe kwemisipha.
Ngaphezu kwalokho, i-taurine ikhishwa emchameni njengefomu lamahhala noma ku-bile njengama-bile salts.Izinso iyisitho esiyinhloko sokuphuma kwe-taurine futhi iyisitho esibalulekile sokulawula okuqukethwe kwe-taurine emzimbeni.Uma i-taurine idlulele, ingxenye eyengeziwe ikhishwa emchameni;lapho i-taurine inganele, izinso zinciphisa ukuphuma kwe-taurine ngokusebenzisa ukumuncwa kabusha.Ngaphezu kwalokho, inani elincane le-taurine liphinde likhishwe emathunjini.
