Amino 80

Cov amino acids dawb ua rau 80% ntawm tag nrho. Lawv muaj 21 hom L-amino acids. Amino acids yog lub luag haujlwm tseem ceeb hauv kev tsim cov protein molecules. Lawv yog cov organic carbon acids ua los ntawm cov amine (NH2) thiab carboxyl (COOH) pawg, nrog rau cov alkyl (R) pawg, uas yog tshwj xeeb rau txhua cov amino acid thiab hu ua sab saw. Lawv khi ntawm alpha carbon atom ( ). Muaj 21 hom amino acids pom nyob rau hauv cov protein, muab faib ua ob pawg: peptide thiab protein (AL-Modhafer, 2009). Amino acids yog bioactivators uas muab cov nroj tsuag nrog lub zog los them rau qhov poob los ntawm kev ua pa thiab decomposition. Lawv yog cov xim tsis muaj xim ionic, soluble mus rau qhov sib txawv hauv cov dej txias, dej kub, thiab dej cawv, thiab muaj qhov sib txawv siab vim lawv yog cov ions hybrid. Amino acids muaj nyob rau hauv cov nroj tsuag nyob rau hauv ib tug dawb lub xeev los yog nyob rau hauv ua ke nrog rau ib leeg los tsim cov proteins thiab peptide tebchaw. Txawm li cas los xij, daim ntawv dawb yog ntau dua, vim nws decomposes peptide bonds thiab ua rau cov amino acids dawb, ib leeg, thiab yooj yim rau nkag mus (Abd EL hafez, 2011). Amino acids kuj tseem pom muaj nyob hauv mitochondria thiab chloroplasts ntawm cov kab mob vim muaj cov ketonic acids uas tshwm sim los ntawm kev sib xyaw ntawm carbohydrates tsim thaum lub sij hawm Kreb (Beavers, 1991). Tus nqi ntawm cov amino acids txawv ntawm ib tsob nroj mus rau lwm qhov nyob ntawm cov txheej txheem metabolic (Abed, 2007), uas tuaj yeem yooj yim kis tau los ntawm cov hauv paus plaub hau thiab dhau los ntawm cov hlab ntsha cog. Amino acids ua lub luag haujlwm tseem ceeb hauv ntau cov txheej txheem biotic, txawm tias lawv tsis pub dawb lossis ua ib feem ntawm cov proteins. Yog li ntawd, lawv qhov tseem ceeb thiab kev ua tau zoo nyob hauv cov theem ntawm cov nroj tsuag loj hlob.
