Precipitation of Casein from Acidic Solutions by Divalent Anions

The solubility of proteins in aqueous buffers depends on the distribution of hydrophilic and hydrophobic amino acid residues on the protein's surface. Hydrophobic residues predominantly occur in the globular protein core, but some exist in patches on the surface. Proteins that have high hydrophobic amino acid content on the surface have low solubility in an aqueous solvent. Charged and polar surface residues interact with ionic groups in the solvent and increase the so… WebThe cellulase-treated meal was extracted with an alkaline solution followed by acid-induced protein precipitation at pH 4.2; the isolated protein was then digested with seven different proteases to generate hydrolysates with a wide range of ACE- and renin-inhibitory activities. notebook hp 15s-fq5083tu natural silver
