Umahluko phakathi kweepeptides kunye neepeptide chain

Umahluko phakathi kweepeptides kunye neepeptide chain zezi:

1.indalo eyahlukileyo.

2.Iimpawu ezahlukeneyo.

3.inani leeamino acids ezahlukeneyo.

Ngaba yenziwe nge-amino acid ye-amino acid ye-molecular peptide yi-polypeptide, ubunzima bayo be-molecular ngezantsi kwe-10000 Da, inokudlula kwi-membrane e-semipermeable, engagqithwanga yi-trichloroacetic acid kunye ne-ammonium sulfate.ikhonkco lepeptide ligama lebhayoloji, elidityaniswe kukuphelelwa ngamanzi emzimbeni kunye nokuxinana kweeamino acid ezininzi ukwenza iibhondi zepeptide (iikhemikhali bonds).

Umahluko phakathi kweepeptides kunye neepeptide chain

1.indalo eyahlukileyo.

I-Polypeptide: Ikhompawundi ye-α-amino acids edityaniswe kunye ngamabhondi e-peptide.Yimveliso ephakathi yeproteolysis.

I-Peptide CHAIN: Zonke ii-amino acids ezimbini ezidityaniswe ukuze zenze i-peptide bond, ii-amino acids ezininzi ezidityaniswe ukuze zenze i-multiple peptide bond, ikhonkco lee-amino acids ezidityaniswe enye kwenye equlethe iibhondi ezininzi ze-peptide.

2. Iimpawu ezahlukeneyo.

Iipeptides: Iipeptides zinoluhlu olubanzi lokunyibilika.Ingxaki ephambili yokungabikho kwe-peptide kukubunjwa kwezakhiwo zesibini."Oku kwenzeka kubo bonke kodwa ezona peptides zigqithisileyo kwaye zibonakala ngakumbi kwiipeptides ezineentsalela ezininzi ze-hydrophobic."

I-Peptide CHAIN: Xa ii-amino acids ezimbini zidibana ukuze zenze i-peptide bond, imolekyuli yamanzi iyakhululwa (okanye yenziwe).Yiyo loo nto zingaphi iipeptide bond bond, zingaphi iimolekyuli zamanzi eziza kuvela.Ngoko ke zingaphi iibhondi ezikhoyo kwikhonkco le-peptide, zingaphi iimolekyuli zamanzi eziya kuphuma.

3.inani le-amino acids lihlukile.

I-Polypeptide: idla ngokusuka kwi-10 ukuya kwi-100 iamino acid iimolekyuli ezijiyaniswa kukuphelelwa ngamanzi emzimbeni.

Iipeptide chain: iipeptides eziqulathe iipeptide ezimbini, iipeptides ezintathu, njalo njalo, kuquka neepeptides.
