I-ethyl nicotinate CAS 614-18-6
I-ethyl nicotinate, eyaziwa ngokuba yi-ethyl pyridine-3-formate ngokwekhemikhali, yi-ester derivative ye-niacin (i-vitamin B3). Lulwelo olungenambala ukuya kolutyheli olucacileyo olunevumba elincinci nelicacileyo leziqhamo. Kwimimandla yorhwebo neyemizi-mveliso, i-ethyl nicotinate ikwaziwa ngokuba yi-ethyl paraben okanye i-ethyl nicotinate. I-ethyl nicotinate ayinyibiliki emanzini kodwa ixutywa nezinyibilikisi ze-organic ezifana ne-ethanol, i-ether kunye ne-chloroform.

1. Icandelo lezonyango: Gxila "ekongezeni iivithamini" kunye "nonyango lwasekuhlaleni"
Njengenxalenye yeyeza ephakathi okanye ethe ngqo, ixabiso eliphambili le-ethyl niacin likwi "ukongeza kwayo okuncinci kwevithamini B3" kunye "nesiphumo sokujolisa kwindawo ethile".
2. Ishishini leekhemikhali lemihla ngemihla: Ukugxila "kukhathalelo lolusu" kunye "nempilo yeenwele"
Ngenxa "yomsebenzi wayo ophantsi + ukuvuleka kakuhle kwesikhumba", i-ethyl niacin isetyenziswa rhoqo "kwiifomyula ezisebenzayo" kwiimveliso zokhathalelo lolusu kunye nokhathalelo lweenwele:
3. Indawo yokutya kunye nokutya: "Ukuqinisa isondlo" kunye "nokuphucula incasa"
Isiqinisekisi sezondlo zokutya
Ukuqinisa iVithamini B3 kwizinto ezibhakiweyo (ezifana nesonka kunye neebhisikithi), iziselo zemidlalo, kunye nokutya okuncedisayo kwiintsana kunye nabantwana abancinci kudla ngokuba nezinga lokongeza eliyi-0.01% ukuya kwi-0.05% (ngokusekelwe kubungakanani bokutya). Umzekelo, ukongeza i-ethyl nicotinate kwi-cereal yerayisi yosana kunokuthintela ubumuncu be-niacin ekuchaphazeleni incasa, ngelixa kwanelisa imfuno yosana yeVithamini B3 (ukutya okucetyiswayo kwemihla ngemihla malunga ne-4mg).
4. Amanye amacandelo: Izicelo zophando lwezemizi-mveliso nolwesayensi
Izinto ezidityanisiweyo ze-organic synthesis: Zisetyenziswa ekudityanisweni kwezinto eziphuma kwi-pyridine (ezifana nezinto ezidityanisiweyo ze-pharmaceutical kunye needayi), kwaye iqela le-ethyl ester lingasebenza "njengeqela elikhuselayo elisuswayo", lizisa amanye amaqela asebenzayo ngokusebenzisa i-hydrolysis okanye ii-reduction reactions.
Izinto ezincedisayo zokunambitha: Isixa esincinci (0.001%-0.005%) esongezwa kwincasa yecuba sinokuphucula incasa ethambileyo yecuba kwaye sifihle ivumba elibi.
I-reagent yophando: Isetyenziswa kwiimvavanyo ze-biochemical njengemolekyuli ye-probe "yophando lwe-niacin metabolism", i-ethyl nicotinate ilandelela indlela yokuguqulwa kwe-niacin ngaphakathi kweeseli.
1. I-ethyl nicotinate ithambile, ayicaphukisi kakhulu kwaye inomngcipheko omncinci wokuhlanjwa. I-ethyl nicotinate ingcono kune-niacin kwaye ifanelekile kulusu olubuthathaka, kunye neemveliso zokhathalelo lolusu olubuthathaka emlonyeni kunye nezongezo zeevithamini zomlomo.
2. I-ethyl nicotinate ifumaneka lula kwaye ingangena lula eluswini nakwi-mucous membranes. Emva kokuba i-hydrolyzed ibe yi-niacin, inomsebenzi ophezulu kwaye ukusebenza kwayo kungaphezulu kune-niacin yangaphandle evuselela igazi kunye neemveliso zokhathalelo lweenwele kunye ne-anti-hair loss.
3. I-ethyl nicotinate iyahambelana kwaye inyibilika lula kwiinkqubo zeoyile/zamanzi, kwaye ayinangquzulwano nezithako ezisetyenziswa xa kusenziwa ii-surfactants, izithinteli zokuguga, iivithamini kunye nezinye izithako. I-ethyl nicotinate yimveliso yokhathalelo lolusu kunye nefomula yokuqinisa ukutya.
4. I-ethyl nicotinate ikhuselekile ukusetyenziswa ngomlomo nangaphandle kwesikhumba kwaye inobungozi obuphantsi kwaye iphumelele iziqinisekiso zokhuseleko kumazwe amaninzi. I-ethyl nicotinate ifanelekile kubantu abaninzi (iintsana kunye nabantu abadala), kuquka ukutya kweentsana kunye nokulungiselela amayeza.
