Yuav Ua Li Cas Pom Cov Amino Acids

Amino acids yog ib qho tseem ceeb, tab sis tseem ceeb chav tsev ntawm cov protein, thiab lawv muaj ib pawg amino thiab pawg carboxylic.Lawv ua lub luag haujlwm tseem ceeb hauv cov txheej txheem gene, uas suav nrog kev hloov pauv ntawm cov protein ua haujlwm uas pab txhawb kev txhais lus RNA (mRNA) (Scot li al., 2006).

Muaj ntau tshaj 700 hom amino acids uas tau pom nyob rau hauv cov xwm.Yuav luag tag nrho lawv yog α-amino acids.Lawv tau pom nyob rau hauv:
• kab mob
• fungi
• algae
• nroj tsuag.

Cov amino acids yog qhov tseem ceeb ntawm peptides thiab cov proteins.Nees nkaum qhov tseem ceeb amino acids yog qhov tseem ceeb rau lub neej vim lawv muaj peptides thiab cov proteins thiab paub tias yog lub tsev thaiv rau txhua yam muaj sia nyob hauv ntiaj teb.Lawv yog siv los ua cov protein synthesis.Cov amino acids yog tswj los ntawm noob caj noob ces.Qee cov amino acids txawv txawv muaj nyob hauv cov noob cog.
Cov amino acids yog tshwm sim los ntawm protein hydrolysis.Thoob plaws ntau pua xyoo, cov amino acids tau pom nyob rau hauv ntau txoj kev, tab sis feem ntau yog los ntawm txoj kev ntawm chemists thiab biochemists ntawm kev txawj ntse siab uas muaj cov kev txawj ntse thiab kev ua siab ntev thiab cov uas muaj tswv yim thiab muaj tswv yim hauv lawv txoj haujlwm.

Protein chemistry yog hnub nyoog laus, nrog qee qhov rov qab ntau txhiab xyoo dhau los.Cov txheej txheem thiab kev siv xws li kev npaj kua nplaum, kev tsim cheese thiab txawm tias qhov kev tshawb pom ntawm ammonia los ntawm kev lim dej ntawm cov quav, tau tshwm sim ntau pua xyoo dhau los.Tsiv mus rau hauv lub sijhawm rau 1820, Braconnot npaj glycine ncaj qha los ntawm gelatin.Nws tau sim tshawb pom seb cov proteins puas ua tau zoo li cov hmoov txhuv nplej siab lossis seb lawv puas yog cov kua qaub thiab qab zib.

Txawm hais tias kev nce qib tau qeeb thaum lub sijhawm ntawd, nws tau txij li tau txais kev nrawm nrawm, txawm hais tias cov txheej txheem nyuaj ntawm cov protein muaj pes tsawg leeg tsis tau pom tag nrho txawm tias niaj hnub no.Tab sis ntau xyoo tau dhau mus txij li Braconnot thawj zaug pib qhov kev soj ntsuam no.

Ntau ntau yuav tsum tau nrhiav pom nyob rau hauv kev tsom xam ntawm cov amino acids thiab nrhiav cov amino acids tshiab.Lub neej yav tom ntej ntawm cov protein thiab amino acids chemistry yog dag hauv biochemistry.Thaum qhov ntawd ua tiav-tab sis tsuas yog txog thaum ntawd peb yuav paub txog cov amino acids thiab cov proteins txaus.Txawm li cas los xij nws zoo li hnub ntawd yuav tsis tuaj sai sai.Qhov no tag nrho ntxiv rau qhov tsis paub, complexities thiab muaj zog scientific nqi ntawm amino acids.
