Phosphatidic acid. Avv iyo muhiimadda in jidhka

Laga soo bilaabo aragtida ah ee qaab-dhismeedka kiimikada, phosphatidic acid waa phospholipid ugu fudud.

walax tani waa mid ka mid ah Dhacdooyinka shiid phosphoglycerides in vivo.

Tani class walxaha la siiyo fiiro badan ee waxbarasho ee hawlaha signal xeryahooda kiimikada.

Si aad u taariikhda, ilaa dhamaadka ma cad oo dhan links ee dheefshiidka ee acids phosphatidic, gaar ahaan, waxaa weli loo arkaa su'aasha ah hab ay of xiriir xogta isugu gudbiyo signal, iyo sidoo kale ku saabsan joogitaanka acids phosphatidic guryaha ionophoric.

Avv phosphatidic acid

formation acid Phosphatidic waxaa saameeya phospholipase D. Tani class of falgalka uu kaalin hoggaamineed ee ereygu wuxuu ahaa ee acids phosphatidic. Sida xarunta kiimikada gaaban-jiray, markii danbe maalkii sarkhaansan fosfogidrolazy hydrolysed in diglyceride (by dephosphorylation reaction).

Marka la acid isla enzyme phosphatidic loo badali karaa oo diacylglycerol, taas oo qabata wareegga ah lagmamaarmaanna u shaqayn reactions activator of tyrosinkinashämmare C. protein eulayska lalana

Avv phosphatidic acid dhaca unugyada adipose. Geedi socodka bilaabmaa rasiidka ee adipocytes (unugyada unugyada adipose) acids dufan sameeyay hydrolysis ee dufanka (badanaa, Lipoproteins cufnaanta aad u yar). Inside gacanta, lalana xiriiro glycerol-iyo-phosphate, acids dufanka leh marka hore diinta lysophosphatidic acid, kaas oo ay markii danbe la aasaasay phosphatidic acid.

Formula sameeyay xaggeeda glycerophospholipids phosphoric kooban harta ee acids dufanka leh, glycerol, iyo anions nitrogen-ka kooban.

Macnaha phosphatidic acid

Waxa la ogaaday in acid ee phosphatidic waa waxa loogu yeero xiriir digayaan, in uu yahay, kuwa shaqada ah dhex- in gudbinta macluumaadka wadooyinka oo signal ah. Gaar ahaan, waa link a muhiimka ah ee la isugu gudbiyo oo ka mid ah calaamadaha ee unugyada dhirta:

• cytokinin;
• osmotic in uu qiimo ah ee horumarinta jawaab gacanta in noocan oo kale ah stress.

Inta lagu guda jiro tijaabo waxaa lagu muujiyay in heerka xarunta unugyada bandhigi noolaha dhirta arrimo pathogenic si weyn u kordhiyaa. dareen-celin Taasina waxay keentaa in:

• stress osmotic.
• heerkulku hooseeyo.
• Saamaynta of sinji qaarkood isagoo asal ahaan khudradda (phytohormones) a.

Sidaas darteed, waxaa la Xukumi karo qaybgalka acid phosphatidic iyo metabolites ay dareen diidmo adag oo masuul ka ah la qabsashada ee u shaqeeyo in xaalado walaac.

Intaas waxaa sii dheer, waxaa la og yahay in acid ee phosphatidic muhiim u tahay gaadiidka ee protons iyo dareen-celinta ah ee atammada kalsiyamku dhex xuubka ee neurons iyo macdantaa muruqa. Iyadoo la raacayo, phosphatidic acid iyo sidoo kale ionophore shaqo sheegtaan (eegista: Runbaana calcium iyo protons).

farsamo transduction

Inkastoo ujeedada phosphatidic acid si toos ah helay habka (hab) ee la isugu gudbiyo signal ayaa weli laga dooday oo u baahan faahfaahinta.

Si kastaba ha ahaatee waxaa shaki ku jirin in transduction waxaa mahad qaadeen in awoodda phosphatidic acid, saamayn ku dhismeedka gacanta of xuub, xuub nidaaminaya waxqabad ee ensaymes, iyo sidoo kale ka qayb-dhexgalka la taagoo protein xuub gacanta.

Codsiga of phosphatidic acid

Studies leeyihiin dhaqdhaqaaqa antioxidant of taagayo of phosphatidic acid, sameeyay sida daraasadda ee geedi socodka model oo ku lug leh walxaha noolaha ayaa muujiyey in wax-u mimetics acid phosphatidic hantidaan hannaanka antioxidant ah hababka of talaabo.

macluumaad dhammaystiran oo ku saabsan jihada of tallaabo of phosphatidic acid u ogolaanaya in ay iyada iyo metabolites ay isticmaasho wax soo saarka ee walxaha bayoloji firfircoon loogu talagalay in kor loogu qaado waxqabadka iyo dulqaadashada unugyada.

Ku-simaha on heerka gacanta, xeryahooda sida ma kicin, laakiin kan caadiga ah oo kaliya unugyada; dhibic muhiim u tahay si loo yareeyo khatarta ka mid ah waxyeellooyin xun.
