additional information
-
lower beta-glucuronidase activity is significantly associated with higher intakes of calcium, iron, and magnesium. Several dietary and nondietary factors are associated with beta-glucuronidase activity. The botanical families Cruciferae, Rutaceae, Compositae, Roseaceae, and Umbelliferae might decrease the enzyme activity when being part of the diet

adsorption of beta-glucuronidase on biopolymers is studied by the retention of the enzyme on the membrane of a concentrator with a pore diameter of 300 kDa and by native PAGE. Pectin-protein complexes (fractions PPC/CP and PPC/C) are established to increase the activity of beta-glucuronidase by 50 and 100%, respectively. There is a positive correlation between the increase of beta-glucuronidase activity in the presence of carbohydrates and enzyme adsorption on the polymers. The activity of the enzyme in the gel after electrophoresis of the PPC/+ beta-glucuronidase mixture is inversely proportional to the concentration of PPC/C in the mixture

additional information

higher beta-glucuronidase activity is significantly associated with being male, over 30 years old, non-Caucasian, overweighted, and exhibiting higher intakes of gamma-tocopherol. Several dietary and nondietary factors are associated with beta-glucuronidase activity
