Budada Nikotinamide adenine dinucleotide (NAD) budada (53-84-9)

Budada Nikotinamide adenine dinucleotide (NAD) waa cofactor oo udub dhexaad u ah dheef-shiid kiimikaadka. Waxaa laga helaa dhammaan unugyada nool, budada NAD waxaa loo yaqaannaa 'dinucleotide' maxaa yeelay waxay ka kooban tahay laba nucleotides oo ku biirtay kooxdooda fosfoolka. Hal nucleotide waxay ka kooban tahay adenine nucleobase iyo tan kale ee nicotinamide. Budada NAD ayaa ku jirta laba qaab: qaab nafaqaysan iyo mid hoos loo dhigay, oo loo soo gaabiyo NAD + iyo NADH siday u kala horreeyaan.

Budada NAD (53-84-9) Tilmaanta Guud

Budada NAD, oo loo soo gaabiyo nicotinamide adenine dinucleotide. Qalabka loo yaqaan 'coenzyme' oo ku dhaca unugyo badan oo nool wuxuuna u shaqeeyaa sida aqbalaadda elektaroniga. Budada NAD waxaa loo istcimaalaa si isdaba-joog ah oo loo yaqaan 'NADH' oo ah oksijiin ama yareynta wakiil falcelinta dheef-shiid kiimikaadka.

 

Nicotinamide adenine dinucleotide Taariikhda

Coenzyme NAD + waxaa markii ugu horeysay soo saaray aqoonyahanada Ingriiska ee Arthur Harden iyo William John Young sanadkii 1906. Waxay ogaadeen in lagu daro soosaarida khamiirka la kariyey iyo la sifeeyey ay aad u dardar gelisay khamiirka khamriga ee soosaarida khamiirka aan la karin Waxay ugu yeereen qodobka aan la aqoonsan ee mas'uulka ka ah saameyntan in loo diro. Iyada oo loo marayo nadiifinta dheer ee adag ee laga soosaaray khamiirka, qodobkaan kuleylka-xasilloon waxaa loo aqoonsaday inuu yahay nukleotide fosfooza Hans von Euler-Chelpin. Sanadkii 1936, saynisyahankii Jarmalka Otto Heinrich Warburg wuxuu muujiyey shaqada nukleotide coenzyme ee wareejinta hydride wuxuuna aqoonsaday qaybta nicotinamide inay tahay goobta falcelinta redox.

Faytamiinyaashii ka horreeyay ee NAD + waxaa markii ugu horreysay la aqoonsaday 1938, markii Conrad Elvehjem uu muujiyay in beerku leeyahay "lidka carrabka madow" waxqabadka ee qaabka nikotinamide. Kadib, 1939, wuxuu bixiyay cadeyntii ugu horeysay ee xoogan ee ah in niacin loo adeegsado sameynta NAD +. Horraantii 1940-yadii, Arthur Kornberg wuxuu ahaa qofkii ugu horreeyay ee lagu arko enzyme marinka biosynthetic. 1949, cilmi-baareyaasha Mareykanka Morris Friedkin iyo Albert L. Lehninger wuxuu cadeeyay in NADH ay kuxirantahay dariiqooyinka dheef-shiid kiimikaadka sida wareegga asiidhka oo leh isku-darka ATP ee fosforyaalka oksida. 1958, Jack Preiss iyo Philip Handler waxay ogaadeen dhexdhexaadiyeyaasha iyo enzymes-yada kujira biosynthesis ee NAD +; Soo-saaridda samatabbixinta ee nikotin-ka waxaa loo yaqaan dariiqa Preiss-Handler. Sannadkii 2004, Charles Brenner iyo wada-shaqeeyeyaashu waxay daaha ka rogeen jidka nicotinamide riboside kinase ee NAD +

 

Budada NAD (53-84-9) Farsamooyinka Ficil

Budada Nikotinamide adenine dinucleotide (NAD) waxay ku lug leedahay falcelinta redox, iyadoo xambaarta elektiroonigga laga qaado hal fal oo loo gudbo mid kale. Cofactor-ka, ayaa sidaas darteed, laga helaa laba qaab unugyada: NAD + waa maaddo sunta oksidheeye ah - waxay ka aqbashaa elektaroonikyada moleekulada kale waana ay yaraanayaan. Falcelintaani waxay samaysaa NADH, oo markaa loo istcimaali karo sidii wakiilka dhimista si loogu deeqo elektaroonigga. Jawaab-celinta elektaroniga ayaa ah shaqada ugu weyn ee NAD. Si kastaba ha noqotee, waxaa sidoo kale loo isticmaalaa qaababka kale ee unugyada, gaar ahaan qeyb yar oo ka mid ah enzymesyada kuwaas oo ku daraya ama ka saaraaya kooxaha kiimikada ah borotiinada, isbadallada kadib. Sababta oo ah muhiimadda howlahan, enzymes-yada ku lug leh dheef-shiid kiimikaadka NAD waa bartilmaameedyada daahfurka daroogada.

NAD + wuxuu door muhiim ah ka ciyaaraa ka caawinta unugyada maskaxda inay si wanaagsan u da 'yaraadaan.

Unugyada maskaxda gudahooda, NAD + wuxuu gacan ka geystaa xakameynta wax soo saarka PGC-1-alpha, oo ah borotiin u muuqda inuu ka caawinayo unugyada ka hortagga culeyska oksidheerka iyo naafanimada shaqada mitokondria. Cilmi baarayaashu waxay aaminsan yihiin in walbahaarka oksidheer iyo shaqada mitochondrial ee daciifka ahi ay ku xiran yihiin cilladaha maskaxda la xiriira da'da sida Alzheimers iyo cudurka Parkinson.

  1. Halista Cudurada Wadnaha ee Hoose

Gabowgu waa halista ugu weyn ee cudurada wadnaha, waana sababta ugu badan ee dadka u dhintaan. Waxay sababi kartaa xididdada dhiigga sida aortaada inay noqdaan kuwo dhumuc weyn, adag oo jilicsan. Isbedelada noocan oo kale ah waxay sare u qaadi karaan heerarka cadaadiska dhiigga waxayna qalbigaaga ka dhigi karaan mid aad u shaqeeya.

Xayawaannada, kor u qaadista NAD + waxay ka caawisay dib-u-beddelada da'da la xiriira ee halbowleyaasha

  1. Waxaa laga yaabaa inay yareyso halista kansarka

Heerarka sare ee NAD + waxay ka hortagaan waxyeelada DNA iyo walaaca oksidheeka ah, ee ku xiran horumarka kansarka

  1. Waxaa laga yaabaa inay kor u qaaddo da'da murqaha caafimaadka leh

Kordhinta heerarka NAD + waxay gacan ka gaysatey hagaajinta shaqada muruqyada, adkeysiga iyo adkeysiga jiirka waaweyn
