Edemede na ozi ngwaahịa niile enyere na webụsaịtị a bụ naanị maka mgbasa ozi na ebumnuche mmụta.
Ngwaahịa ndị enyere na webụsaịtị a bụ naanị maka nyocha in vitro. A na-eme nyocha in vitro (Latin: * na iko *, nke pụtara na ihe eji enyo) na mpụga ahụ mmadụ.

Kedu ihe bụ Peptide Solubility?
Peptide solubility na-ezo aka na oke peptide nwere ike igbari n'ime otu olu nke ihe mgbaze n'okpuru ọnọdụ okpomọkụ kpọmkwem na ọnọdụ pH, nke a na-ejikarị mkpokọta mkpokọta (g / L) ma ọ bụ mkpokọta molar (mol / L). Dị ka ihe onwunwe physicochemical dị oke egwu, ọ na-emetụta kpọmkwem ntinye, nkesa, metabolism, na excretion (ADME) nke peptides na vivo, ma na-ekpebikwa nkà na ụzụ nkwadebe, nkwụsi ike nchekwa, na ngwa ngwa ụlọ ọgwụ nke ọgwụ ndị dabeere na peptide.
Ihe ndị dị mkpa na-emetụta Peptide Solubility
A na-ekpebi solubility peptide site n'ụdị molekụla na gburugburu mpụta. N'ọkwa molekụla, amino acids polar na-eme ka hydrophilicity site na njikọ hydrogen ma ọ bụ njikọ ion, si otú ahụ na-eme ka solubility dịkwuo mma; Amino acid ndị na-abụghị polar na-agbakọta ọnụ n'ihi mmekọrịta hydrophobic, na-ebelata solubility. Peptides dị mkpụmkpụ na-egosipụtakarị solubility dị elu karịa ogologo peptides n'ihi nha molekụla ha dị ntakịrị na mmetụta ngwọta siri ike. Peptides nwere nkesa ụgwọ otu nwere oke solubility dị elu na ụkpụrụ pH kwesịrị ekwesị n'ihi mbelata nchịkọta nke mkparị electrostatic kpatara. N'ime ọnọdụ mpụga, polarity ihe mgbaze, uru pH na ike ionic niile na-emetụta omume mgbasa.

Atụmatụ dị irè maka ịkwalite Peptide Solubility
Mgbanwe kemịkalụ gụnyere iwebata ndị otu pola na peptide termini ma ọ bụ dochie amino acid na-abụghị polar na ihe fọdụrụnụ iji kwalite hydrophilicity na ibelata mmekọrịta hydrophobic. Nkwalite usoro mgbaze gụnyere ịgbakwunye ihe mgbaze organic (methanol, DMSO) ma ọ bụ surfactants (SDS) iji melite polarity mgbaze ma ọ bụ mepụta micelles maka solubilization.
