T Matsumoto et al.
Analytical biochemistry, 138(1), 133-136 (1984-04-01)
A detailed procedure of a new and extremely sensitive fluorometric assay for amine oxidases is presented. Hydrogen peroxide, produced by the oxidase reaction, reacted with 3-(p-hydroxyphenyl)propionic acid in the presence of peroxidase to yield a fluorescent compound by which enzyme
Alessandro Granata et al.
Chemistry (Weinheim an der Bergstrasse, Germany), 12(9), 2504-2514 (2005-12-13)
The activity of mushroom tyrosinase towards a representative series of phenolic and diphenolic substrates structurally related to tyrosine has been investigated in a mixed solvent of 34.4% methanol-glycerol (7:1, v/v) and 65.6% (v/v) aqueous 50 mM Hepes buffer at pH
Seon-Min Jeon et al.
Translational research : the journal of laboratory and clinical medicine, 149(1), 15-21 (2007-01-02)
This study was conducted to compare the hypocholesterolemic and antioxidant effects of naringenin (0.02%), and its metabolites, rho-hyproxyphenylpropionic acid (PHPP, 0.012%) and rho-hydroxybenzoic acid (PHB, 0.012%), in 1% cholesterol diet-fed rats. All supplements significantly lowered the plasma total-cholesterol (total-C), triglyceride

Peptides, 11(2), 271-275 (1990-03-01)
We have developed a specific and sensitive radioimmunoassay for the hydra head activator neuropeptide (HHAP). The antibody recognizes the C-terminal portion of HHAP and shows no cross-reactivity with other neuropeptides. The assay allows measurement of HHAP-like material in tissue extracts
A P Jarvis et al.
Planta, 212(1), 119-126 (2001-02-24)
Stable-isotope-labelled (2H6, 18O) 3-hydroxy-3-phenylpropanoic acid, a putative intermediate in the biosynthesis of benzoic acid (BA) and salicylic acid (SA) from cinnamic acid, has been synthesized and administered to cucumber (Cucumis sativus L.) and Nicotiana attenuata (Torrey).
