Specifications

Hydroxyethyl cellulose (HEC) is a non-ionic, water-soluble polymer derived from cellulose through a series of chemical and physical processes.

HELLUTEL HEC is a white to light yellowish, oderless and tastless powder, readily soluble in hot or cold water to form a viscous gel solution. When pH in solution is within 2 to 12, the solution is quite stable. Since HELLUTEL HEC group is nonionic one in water solution, it won't be reacted with other anions or cations and insensitive to the salts. But HEC molecule is capable of generating esterification, etherification and acetal reaction, so it is possible to make it insoluble in water or improve its properties.HELLUTEL HEC also has good film-forming ability and surface activity.

Chymotrypsin is also called chymotrypsinogen.

Chymotrypsin is the endopeptidase extracted and separated from the fresh pancreas of cows (or pigs).

Primary structure and spatial structure of α- Chymotrypsin have been clearly explained, which is a single peptide chain composed of 245 amino acid residues, with 5 pairs of disulfide linkage in the molecule.

Chymotrypsin is white and light yellow crystal or amorphous powder, and easily soluble in the water, but insoluble in organic solvent. Relative molecular mass is 24000, and the optimum PH is 8~9.

Chymotrypsin is stable at a dry state, but will be quickly deactivated in water solution, most stable in the water solution with PH3~4. When it acts on the protein, Chymotrypsin will hydrolyze the peptide bond formed by the carboxyl of L-tyrosine and L-phenylalanine in priority.
