Qhov sib txawv tseem ceeb ntawm cov amino acid thiab imino acid yog tias cov amino acid muaj ib pawg amino thiab pawg carboxylic ua ke nyob rau hauv tib lub molecule whereas imino acid muaj ib pawg imino thiab ib pawg carboxylic ua ke.
Txawm hais tias cov ntsiab lus amino acid thiab imino acid suab zoo ib yam, lawv yog ob lo lus sib txawv peb siv los ua ob lub tebchaw sib txawv. Ib qho amino acid yog lub tsev thaiv cov proteins. Imino acids kuj muaj feem xyuam rau cov amino acids vim peb tuaj yeem hloov cov amino acid rau hauv imino acid.
Amino Acid yog dab tsi?
Ib qho amino acid yog cov organic molecule uas ua raws li lub tsev thaiv cov proteins. Nws tseem ceeb muaj ib pawg amine (-NH 2), pawg carboxylic (-COOH), alkyl pawg (-R) thiab hydrogen atom (-H) txuas rau tib lub hauv paus carbon atom.. Yog li ntawd, cov tshuaj nyob rau hauv cov amino acid yog carbon, hydrogen, oxygen, thiab nitrogen. Qee lub sij hawm, muaj leej faj thiab.
Daim duab 01: Txawv Amino Acids
Yog tias pawg amine thiab carboxylic pawg ntawm cov amino acid txuas nrog thawj carbon atom ntawm cov saw hlau, peb hu nws ua alpha amino acid. Feem ntau, lo lus amino acid hais txog alpha amino acids vim lawv muaj ntau. Muaj 22 amino acids koom nrog hauv kev tsim cov protein. Peb hu lawv “proteinogenic amino acids”.
Ntawm lawv, cuaj proteinogenic amino acids yog cov amino acids tseem ceeb rau peb vim peb lub cev tsis tuaj yeem tsim nws. Yog li ntawd, peb yuav tsum coj lawv los ntawm sab nraud, piv txwv li cov khoom noj. Lwm cov amino acids tuaj yeem tsim hauv peb lub cev; yog li no, tsis tas yuav coj lawv tawm sab nraud.
YImino Acid yog dab tsi?
Ib imino acid yog cov organic compound uas muaj imino pawg thiab pawg carboxylic ua ke. Peb tuaj yeem txheeb xyuas pawg imine li (>C=NH). Yog li ntawd, tsis zoo li hauv cov amino acids, cov molecules muaj ob daim ntawv cog lus ntawm carbon thiab nitrogen atoms.
Daim duab 02: Imine Group Txuas rau Carbon
Qee cov enzymes tuaj yeem hloov cov amino acids rau hauv imino acids. Piv txwv li, D-amino acid oxidase enzymes yog cov enzymes. Ntxiv mus, proline muaj cov pab pawg amine thib ob (peb hu ua imine), tsis yog thawj pawg amine. Li no, peb hu proline ib "imino acid".
Qhov txawv ntawm Amino Acid thiab Imino Acid yog dab tsi?
Ib qho amino acid yog cov organic molecule uas ua lub tsev thaiv cov proteins thaum lub imino acid yog cov organic molecule uas muaj ib pawg imine. Yog li, qhov sib txawv tseem ceeb ntawm cov amino acid thiab imino acid yog tias cov amino acid muaj ib pawg amino thiab carboxylic pawg ua ke nyob rau hauv tib lub molecule whereas imino acid muaj ib pawg imino thiab ib pawg carboxylic ua ke.
Ntxiv mus, cov tshuaj tiv thaiv ntawm nruab nrab cov pa roj carbon atom thiab nitrogen atom ntawm cov amino pawg hauv cov amino acids yog ib daim ntawv cog lus thaum kev sib cog lus ntawm nruab nrab carbon atom thiab nitrogen atom ntawm imine pawg yog ob daim ntawv cog lus. Yog li, peb tuaj yeem txiav txim siab qhov no kuj yog qhov sib txawv ntawm cov amino acid thiab imino acid.
Summary – Amino Acid vs Imino Acid
Neeg feem coob tsis meej pem ob lo lus amino acid thiab imino acid xav tias lawv yog tib yam. Txawm li cas los xij, muaj qhov sib txawv ntawm cov amino acid thiab imino acid. Qhov sib txawv tseem ceeb ntawm cov amino acid thiab imino acid yog cov amino acid muaj ib pawg amino thiab pawg carboxylic ua ke nyob rau hauv tib lub molecule whereas imino acid muaj ib pawg imino thiab ib pawg carboxylic ua ke.
