Ph of chymotrypsin
WebChymotrypsinogen C has been prepared from frozen and lyophilized pancreatic juice of young pigs by chromatography on DEAE-cellulose (pH 6.0), gel filtration on Sephadex G-100, and further ion-exchange chromatography on CM-Sephadex (pH 6.0). The yield was about 60–70 mg of chymotrypsinogen C from 15 g of lyophilized pancreatic juice [3]. WebIn chemistry, pH is a numeric scale used to specify the acidity or basicity (alkalinity) of an aqueous solution. It is roughly the negative of the logarithm to base 10 of the concentration, measured in units of moles per liter, of hydrogen ions. More precisely it is the negative of the logarithm to base 10 of the activity of the hydrogen ion.

WebDec 17, 2024 · Chymotrypsinogen, the inactive form of chymotrypsin, is initially formed in the pancreas and consists of 245 amino acids. Amino acids are the building components …
Chymotrypsin is synthesized in the pancreas. Its precursor is chymotrypsinogen. Trypsin activates chymotrypsinogen by cleaving peptidic bonds in positions Arg15 – Ile16 and produces π-chymotrypsin. In turn, aminic group (-NH3 ) of the Ile16 residue interacts with the side chain of Asp194, producing the "oxyanion hole" and the hydrophobic "S1 pocket". Moreover, chymotrypsin induces its own activation by cleaving in positions 14–15, 146–147, and 148–149, producing α-c… WebFeb 12, 2024 · which is in agreement with the observed zeroth-order kinetics of Figure 7.2.2.
