Pi protein solubility

WebProtParam (References / Documentation) is a tool which allows the computation of various physical and chemical parameters for a given protein stored in Swiss-Prot or TrEMBL or for a user entered protein sequence. The computed parameters include the molecular weight, theoretical pI, amino acid composition, atomic composition, extinction coefficient, … WebFeb 1, 2005 · The solubility was determined experimentally in the range of 40–60°C for temperature and 3.5–7.8 for pH. The results showed that, both temperature and pH influenced in the protein solubility, and these properties had great interaction.

WebThe pI value can affect the solubility of a molecule at a given pH. Such molecules have minimum solubility in water or salt solutions at the pH that corresponds to their pI and … WebIn general, protein soluble at lower pH (Protonate), protein soluble at high pH (deprotonate). To move the pH away from pI increases the solubility of the protein, and more likely to decrease the electro-repulsion at low salt concentrations and prevent the aggregation and precipitation problems.

WebThe solubility of a protein is usually at a minimum at its isoelectric point. The isoelectric point is defined as the pH at which a protein has a net charge of zero. For casein, due to the attached phosphate groups, the isoelectric point is close to pH = 4.
