Compositional analyses of heparin (Hep) and heparan sulfate (HS) have been undertaken with disaccharide units obtained by either enzymatic digestion with heparitinases or hydrazinolysis/deamination reaction of polysaccharides. Unsaturated disaccharide units generated by the enzymatic method are detectable on HPLC with

4-n-Butylamino-5-ethyl-1,2-benzoquinone (1(ox)) has been synthesized as a model compound for the LTQ (lysine tyrosyl quinone) cofactor of lysyl oxidase (LOX). At pH 7, 1(ox) has a lambda(max) at 504 nm and exists as a neutral o-quinone in contrast to a

Three spectrophotometric methods were developed for the microdetermination of decamethrin in insecticidal formulations and in water. The methods are based on the hydrolysis of decamethrin with methanolic KOH to 3-phenoxybenzaldehyde; condensation of the hydrolysis product with 2,4-dinitrophenylhydrazine (2,4-DNPH), 4-nitrophenyl-hydrazine (4-NPH)

Structural properties of dimeric (2 x 75 kDa) copper-containing amine oxidase (EC 1.4.3.6) from Aspergillus niger were studied. The enzyme treated with SDS was dissociated into subunits which showed different mobility on polyacrylamide gel without SDS. The separated subunits had
