I-Ethyl nicotinate CAS 614-18-6
I-ethyl nicotinate, eyaziwa ngamakhemikhali ngokuthi i-ethyl pyridine-3-formate, iyi-ester derivative ye-niacin (i-vitamin B3). Iwuketshezi olukhanyayo olungenambala kuya koluphuzi olukhanyayo olunephunga elincane, elihlukile lezithelo. Emasimini ezentengiselwano nasezimbonini, i-ethyl nicotinate yaziwa nangokuthi i-ethyl paraben noma i-ethyl nicotinate. I-ethyl nicotinate ayincibiliki emanzini kodwa ixubana nezinyibilikisi eziphilayo ezifana ne-ethanol, i-ether kanye ne-chloroform.

1. Insimu yezokwelapha: Gxila "ekungezeni amavithamini" kanye "nokwelashwa kwendawo"
Njengengxenye yezokwelapha eqondile noma esetshenziswa ngqo kwezokwelapha, inani eliyinhloko le-ethyl niacin lisekuhlanganisweni kwayo okuthambile kwevithamini B3 kanye "nomphumela wokuhlosa wendawo".
2. Imboni yamakhemikhali yansuku zonke: Ukugxila "ekunakekelweni kwesikhumba" kanye "nempilo yezinwele"
Ngenxa "yomsebenzi wayo omnene + ukuvuleka okuhle", i-ethyl niacin ivame ukusetshenziswa "emafomuleni asebenzayo" emikhiqizweni yokunakekelwa kwesikhumba kanye nezinwele:
3. Insimu Yokudla Nokudla: "Ukuqinisa Ukudla" kanye "Nokuthuthukiswa Kokunambitheka"
Isiqinisi sezakhamzimba zokudla
Ukuqinisa i-Vitamin B3 yezinto ezibhakiwe (njengesinkwa namabhisikidi), iziphuzo zezemidlalo, kanye nokudla okuhambisanayo kwezinsana nezingane ezincane ngokuvamile kunesilinganiso sokwengeza esingu-0.01% kuya ku-0.05% (ngokusekelwe enanini lokudla eliphelele). Isibonelo, ukwengeza i-ethyl nicotinate ku-cereal yelayisi yezingane kungavimbela ubumuncu be-niacin ekuthinteni ukunambitheka, kuyilapho kuhlangatshezwana nesidingo sengane se-vitamin B3 (ukudla okunconywayo kwansuku zonke cishe kungama-4mg).
4. Eminye imikhakha: Izicelo zocwaningo lwezimboni kanye nesayensi
Izinto ezihlanganisa ukwenziwa kwezinto eziphilayo: Zisetshenziswa ekuhlanganisweni kwezinto ezisuselwa ku-pyridine (njengezinto ezihlanganisa ukwenziwa kwemithi kanye nodayi), futhi iqembu le-ethyl ester lingasebenza "njengeqembu elivikelayo elisuswayo", lethula amanye amaqembu asebenzayo ngokusebenzisa i-hydrolysis noma ukusabela kokunciphisa.
Izakhi ezisizayo zokunambitha: Inani elincane (0.001%-0.005%) elifakwe ekunambithekeni kukagwayi lingathuthukisa ukunambitheka okumnandi kukagwayi futhi livale iphunga elinobuthi.
I-reagent yocwaningo: Isetshenziswa ekuhlolweni kwamakhemikhali njenge-molecule ye-probe "yocwaningo lwe-metabolism ye-niacin", i-ethyl nicotinate ilandelela indlela yokuguqulwa kwe-niacin ngaphakathi kwamaseli.
1. I-ethyl nicotinate ithambile, ayicasuli kakhulu futhi inengozi encane yokuhlanzeka. I-ethyl nicotinate ingcono kune-niacin futhi ifanele isikhumba esibucayi, kanye nemikhiqizo yokunakekelwa kwesikhumba ebucayi emlonyeni kanye nezithasiselo zamavithamini zomlomo.
2. I-ethyl nicotinate inamandla aphezulu okutholakala kwezinwele futhi ingangena kalula esikhumbeni nasemikhunjini yama-mucous. Ngemva kokufakwa i-hydrolyzed ibe yi-niacin, inomsebenzi ophezulu futhi ukusebenza kwayo kahle kudlula okwe-niacin yangaphandle esebenza ngegazi kanye nemikhiqizo yokunakekelwa kwezinwele kanye neyokulwa nokulahlekelwa izinwele.
3. I-ethyl nicotinate iyahambisana futhi incibilika kalula ezinhlelweni zamafutha/zamanzi, futhi ayinazo izingxabano nama-surfactants, izithako zokugcina, amavithamini nezinye izithako. I-ethyl nicotinate iwumkhiqizo wokunakekelwa kwesikhumba ohlanganisiwe kanye nefomula yokuqinisa ukudla.
4. I-ethyl nicotinate iphephile ukusetshenziswa ngomlomo nangaphandle komuthi futhi ithole izitifiketi zokuphepha emazweni amaningi. I-ethyl nicotinate ifanelekela abantu abaningi (izinsana nasebekhulile), okuhlanganisa ukudla kwezinsana kanye nokulungiselela imithi.
