Alan-Alanine (lossis beta-alanine) yog ib txwm muaj ntau cov amino amino acid, uas yog cov amino acid uas cov amino pawg nyob ntawm position-txoj haujlwm los ntawm pawg carboxylate (piv txwv li, ob qho atoms tawm, saib Daim Duab 1). Lub npe IUPAC rau β-alanine yog 3-aminopropanoic acid. Tsis zoo li nws cov counterpart-alanine, β-alanine tsis muaj lub tso suab.

Alan-Alanine tsis raug siv nyob rau hauv biosynthesis ntawm cov protein loj lossis cov enzymes. Nws yog tsim nyob rau hauv vivo los ntawm kev ua kom zoo ntawm dihydrouracil thiab carnosine. Nws yog qhov sib xyaw los ntawm peptides carnosine thiab anserine thiab ib txwm muaj pantothenic acid (vitamin B5), uas nws tus kheej yog ib qho kev sib xyaw ntawm coenzyme A. Raws li ib txwm mob, β-alanine yog metabolized rau hauv acetic acid.

Alan-Alanine yog tus nqi-txiav txim siab ua ntej ntawm carnosine, uas yog hais txog qib carnosine yog txwv los ntawm cov nyiaj muaj amount-alanine, tsis yog histidine. Kev txhawb ntxiv nrog β-alanine tau pom tias ua rau kom cov concentration ntawm carnosine hauv cov leeg nqaij, txo kev qaug zog ntawm cov neeg ncaws pob thiab nce tag nrho cov leeg ua haujlwm. Tsuas ntxiv nrog cov carnosine tsis zoo li kev ntxiv nrog with-alanine ib leeg txij li carnosine, thaum noj ntawm qhov ncauj, tau tawg thaum lub sij hawm kev zom rau nws cov khoom, histidine thiab β-alanine. Li no, los ntawm qhov hnyav, tsuas yog kwv yees li 40% ntawm cov koob tshuaj muaj li β-alanine.

L-Histidine, nrog pKa ntawm 6.1 yog qhov tsis muaj zog ntawm lub zog ntau dua li cov physiological intramuscular pH ntau. Txawm li cas los xij, thaum khi rau lwm cov amino acids, qhov no nce ntxiv ze rau 6.8-7.0. Hauv kev tshwj xeeb, thaum khi rau β-alanine, tus nqi pKa yog 6.83, ua qhov no ua kom muaj kev cuam tshuam intramuscular tsis ntau. Tsis tas li ntawd, vim hais tias ntawm txoj haujlwm ntawm beta amino pawg, β-alanine dipeptides tsis yog kev koom ua ke nrog cov protein, thiab yog li tuaj yeem muab tso rau ntawm qhov kev sib txuam ntau (millimolar). Muaj tshwm sim ntawm 17-25mmol / kg (cov leeg qhuav), carnosine (al-alanyl-L-histidine) yog qhov tseem ceeb ntawm intramuscular tsis, suav nrog 10-20% ntawm tag nrho cov muaj peev xwm tiv thaiv hauv hom I thiab II cov leeg nqaij.

Txawm hais tias lub zog qis dua li ntawm glycine (thiab, yog li, nrog lub luag haujlwm sib cav ua lub zog xa tawm), β-alanine yog agonist tom ntej hauv kev ua si rau lub cognate ligand glycine nws tus kheej, rau strychnine-rhiab inhibitory glycine receptors (GlyRs) (agonist kev txiav txim: glycine ≫ β-alanine> taurine ≫ alanine, L-serine> proline).

Cov khoom hauv qab patent yog muab rau R& D lub hom phiaj nkaus xwb. Txawm li cas los xij, lub luag haujlwm kawg tau txiav txim siab nrog cov neeg yuav khoom.
