Phapang lipakeng tsa liketane tsa peptide le peptide ke:
1.sebopeho se fapaneng.
2.Litšobotsi tse fapaneng.
3.palo ea li-amino acid tse fapaneng.
E entsoe ka li-amino acid tse tharo kapa ho feta tsa limolek'hule tsa peptide ke polypeptide, boima ba eona ba molek'hule e ka tlase ho 10000 Da, e ka feta ka har'a lera le nang le semipermeable, le sa kenngoeng ke trichloroacetic acid le ammonium sulfate.ketane ea peptide ke lentsoe la baeloji, le hokahantsoeng ke ho felloa ke metsi 'meleng le condensation ea li-amino acid tse ngata ho theha bond ea peptide (li-chemical bonds).
Phapang lipakeng tsa liketane tsa peptide le peptide
1.sebopeho se fapaneng.
Polypeptide: Motsoako oa α-amino acid e hokahantsoeng ka bond ea peptide.Ke sehlahisoa sa mahareng sa proteolysis.
Peptide CHAIN: Li-amino acid tse ling le tse ling tse peli tse hokahantsoeng ho theha bond ea peptide, li-amino acid tse ngata tse hokahantsoeng ho theha bond ea li-peptide tse ngata, ketane ea li-amino acid tse hokahantsoeng tse nang le li-bond tse ngata tsa peptide.
2. Litšobotsi tse fapaneng.
Li-peptides: Li-peptide li na le mefuta e mengata ea ho qhibiliha.Bothata bo ka sehloohong ba ho insolubility ha peptide ke ho thehoa ha mehaho ea bobeli."Sena se etsahala ho bohle ntle le li-peptide tse feteletseng ka ho fetesisa 'me se tsebahala haholo bakeng sa li-peptide tse nang le masala a mangata a hydrophobic."
Peptide CHAIN: Ha li-amino acid tse peli li kopana ho theha bond ea peptide, molek'hule oa metsi oa lokolloa (kapa oa thehoa).Ke hore na li-peptide bond li theha li kae, ho tla hlaha limolek'hule tse kae tsa metsi.Kahoo ho na le li-bond tse kae ka ketane ea peptide, ke limolek'hule tse kae tsa metsi tse tla tsoa.
3.palo ea li-amino acid e fapane.
Polypeptide: hangata ho tloha ho limolek'hule tse 10 ho isa ho tse 100 tsa amino acid tse hoketsoang ke ho felloa ke metsi 'meleng.
Liketane tsa peptide: li-peptide tse nang le li-peptide tse peli, li-peptide tse tharo, joalo-joalo, hape li kenyelletsa le li-peptide.
