title: Analytical biochemistry and clinical significance of N-acetyl-beta-D-glucosaminidase and related enzymes.
abstract: Human N-acetyl-beta-D-glucosaminidase, N-acetyl-alpha-D-glucosaminidase, endo-beta-N-acetylglucosaminidase, hexosaminidase, beta-N-acetylgalactosaminidase and glucocerebrosidase have not been so widely studied as the beta-N-acetylhexosaminidases in bacteria, fungi and arthropods. Their biochemical role has been elucidated, however, and their urinary and plasma determination is being adopted for the early detection of diseases before clinical manifestation, in particular for hypertension, renal injuries and disorders, depression and lysosomal storage diseases. The spectrophotometric determinations of N-acetyl-beta-D-glucosaminidase, most often done with 3-cresolsulphone phthaleinyl N-acetyl-beta-D-glucosaminide, have been recently simplified and adapted to automatic instruments.
