Qhov sib txawv tseem ceeb ntawm hydrophobic thiab hydrophilic amino acids yog tias hydrophobic amino acids tsis yog polar whereas hydrophilic amino acids yog polar.
Amino acids yog lub tsev tsim cov proteins. Cov protein yog ib qho loj heev polymer molecule uas yog ib qho tseem ceeb ntawm tag nrho cov kab mob nyob. Tsis tas li ntawd, cov amino acids feem ntau yog nyob rau hauv ob hom raws li qhov tseem ceeb thiab tsis tseem ceeb amino acids. Ntxiv mus, peb tuaj yeem categorize lawv li hydrophilic thiab hydrophobic amino acids, nyob ntawm seb lawv cov xwm txheej physicochemical. Lawv txawv ntawm ib leeg los ntawm qhov polarity.
Dab tsi yog Hydrophobic Amino Acids?
Hydrophobic amino acids yog ib hom amino acids uas tsis muaj polar xwm. Ib yam li ntawd, lub npe "hydrophobic" muab tau vim nws tsis cuam tshuam nrog dej ("hydro" - dej). Dej yog cov kuab tshuaj polar. Txij li cov amino acids no tsis yog polar, lawv tsis tuaj yeem yaj hauv dej.
Daim duab 01: Qhov tseem ceeb Amino Acids
Li no, qhov xwm txheej hydrophobic ntawm cov tebchaw no tshwm sim vim yog cov saw hlau sab uas lawv muaj hauv lawv cov qauv tshuaj. Ib qho amino acid muaj cov qauv dav dav uas lub hauv paus carbon atom txuas nrog hydrogen atom, pawg carboxyl, pawg amine thiab pawg sab (R pawg). Cov pab pawg R no tuaj yeem yog ib qho atom (hydrogen atom) lossis cov saw ntev ntev. Yog li, yog hais tias sab saw ntev heev thiab muaj feem ntau ntawm carbon thiab hydrogen atoms, lawv yog hydrophobic. Tsis tas li ntawd, lawv muaj lub sijhawm me me dipole. Yog li ntawd, lawv nyiam tawm ntawm dej.
Ntxiv mus, hydrophobic amino acids ntawm cov amino acids tseem ceeb yog raws li hauv qab no.
- YGlycine
- Alanine
- Valine
- Leucine
- Isoleucine
- Proline
- Phenylalanine
- Methionine
- Tryptophan
Dab tsi yog Hydrophilic Amino Acids?
Hydrophilic amino acids yog ib hom amino acids uas muaj qhov polar xwm. Lub npe "hydrophilic" muab tau vim nws nyiam dej. Txij li dej yog cov kuab tshuaj polar thiab cov amino acids tseem yog polar, lawv tuaj yeem yaj hauv dej.
Daim duab 02: Hydrophilic Amino Acids: Serine
Hydrophilic amino acids muaj ob txoj hlua luv luv lossis sab saw nrog hydrophilic pawg. Feem ntau, cov amino acids no tshwm sim ntawm qhov chaw ntawm cov protein molecules, thiab lawv muaj lub sijhawm loj dipole. Yog li ntawd, lawv nyiam nyiam dej.
Ntxiv mus, qhov loj hydrophilic, tseem ceeb amino acids yog raws li nram no:
- Serine
- Threonine
- YCysteine
- Asparagine
- YGlutamine
- YTyrosine
Qhov txawv ntawm Hydrophobic thiab Hydrophilic Amino Acids yog dab tsi?
Hydrophobic amino acids yog hom amino acids uas muaj qhov tsis muaj polar thaum hydrophilic amino acids yog hom amino acids uas muaj qhov polar xwm. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm hydrophobic thiab hydrophilic amino acids. Ntxiv mus, hydrophobic amino acids muaj cov hlua ntev nrog feem ntau carbon thiab hydrogen atoms whereas hydrophilic amino acids muaj ob sab luv luv los yog sab saw nrog hydrophilic pawg. Raws li lwm qhov sib txawv tseem ceeb ntawm hydrophobic thiab hydrophilic amino acids, cov hydrophobic tshwm sim ntawm qhov chaw ntawm cov proteins thaum hydrophilic amino acids nyob rau saum npoo.
Cov duab hauv qab no qhia cov lus piav qhia txog qhov sib txawv ntawm hydrophobic thiab hydrophilic amino acids.
Summary – Hydrophobic vs Hydrophilic Amino Acids
Hauv luv luv, amino acids yog lub tsev tsim cov proteins. Ntxiv mus, raws li polarity, muaj ob hom hydrophilic thiab hydrophobic amino acids. Qhov sib txawv tseem ceeb ntawm hydrophobic thiab hydrophilic amino acids yog tias hydrophobic amino acids tsis yog polar whereas hydrophilic amino acids yog polar.
