Ihe dị iche n'etiti peptides na peptide chains

Ihe dị iche n'etiti peptides na peptide chains bụ:

1. ọdịdị dị iche iche.

2.Different àgwà.

3.ọnụọgụ nke amino asịd dị iche iche.

Ọ mejupụtara atọ ma ọ bụ karịa amino acid peptide molecular bụ polypeptide, ha molekụla arọ n'okpuru 10000 Da, nwere ike gafere a semipermeable akpụkpọ ahụ, ọ bụghị precipitated site trichloroacetic acid na ammonium sulfate.yinye peptide bụ okwu ndu, nke ejikọrọ site na akpịrị ịkpọ nkụ na nsị nke ọtụtụ amino acid iji mepụta njikọ peptide (njikọ kemịkalụ).

Ihe dị iche n'etiti peptides na peptide chains

1. ọdịdị dị iche iche.

Polypeptide: Ngwakọta α-amino acid jikọtara ọnụ site na njikọ peptide.Ọ bụ ngwaahịa dị n'etiti proteolysis.

Agbụ Peptide: Amino acid abụọ ọ bụla jikọtara iji mepụta njikọ peptide, ọtụtụ amino asịd jikọtara ya na-etolite ọtụtụ peptide bond, agbụ nke amino acid jikọtara ibe ha nwere ọtụtụ njikọ peptide.

2. Ụdị dị iche iche.

Peptides: Peptides nwere ọtụtụ ihe solubility.Isi nsogbu na peptide insolubility bụ nguzobe nke ihe owuwu nke abụọ."Nke a na-eme maka ihe niile ma ọ bụghị peptides kachasị njọ ma bụrụ nke a na-akpọkarị maka peptides nwere ọtụtụ ihe fọdụrụ na hydrophobic."

Chain Peptide: Mgbe amino acid abụọ jikọtara ọnụ iji mepụta njikọ peptide, a na-ewepụta molecule mmiri (ma ọ bụ guzobe).Nke ahụ bụ ole peptide bond guzobere, ole molekul mmiri ga-apụta.Yabụ kedu ole nkekọ dị na agbụ peptide, ole mkpụrụ ndụ mmiri ga-apụta.

3.ọnụọgụ nke amino acid dị iche.

Polypeptide: na-emekarị site na 10 ruo 100 amino acid molecules condensed site na akpịrị ịkpọ nkụ.

Agbụ Peptide: peptides nwere peptide abụọ, peptides atọ, wdg, gụnyere peptides.
