Dilute Acid Hydrolysis of Papain

Dilute Acid Hydrolysis of Papain

Studies on the amino acid sequence of papain by means of the that hydrolysis of endopeptide linkages in dilute acid might peptides from the chymotryptic (l-3) and tryptic digests (4, 5) proceed predominantly by a mechanism, independent of hydrogen of the protein have yielded a considerable number of partial ions, involving un-ionized P-carboxyl groups of aspartyl residue. sequences. Four of the...

Kinetic Modelling of Dilute Acid Hydrolysis of Lignocellulosic Biomass

Optimization Study of Citrus Wastes Saccharification by Dilute-acid Hydrolysis

The effects of time, acid concentration, temperature and solid concentration on dilute-acid hydrolysis of orange peels were investigated. A central composite rotatable experimental design (CCRD) was applied to study the individual effects of these hydrolysis factors and also their interdependence effects. The enzymatic hydrolysis of the peels by cellulase, β-glucosidase, and pectinase enzymes r...

Hydrolysis Equilibrium of Dinitrogen Trioxide in Dilute Acid Solution

Solutions of nitrous acid in dilute (0.1 M HCI) or more concentrated ( 5 M HCIOJ acid exhibit a contribution to the ultraviolet absorbance that is quadratic in [HN02]. In dilute acid this excess absorbance is attributed to N2O3 formed through equilibrium 1, 2HN02 = N2O3 + H20. From the measured spectrum of eNf13KI vs. wavelength (245-260 nm) and by comparison with tNS, obtained in pulse radioly...

Dilute acid hydrolysis and fermentation of corn fiber to xylitol

Xylitol, a five-carbon sugar alcohol, has similar sweetening power as sucrose. It has unique pharmacological properties such as prevention of tooth decay and ear infection in children; it is used as a sugar substitute for diabetic patients and in parenteral application to trauma patients. Xylitol is increasingly being used in chewing gums, candy, soft drinks, ice cream and oral hygiene products...
