## Abstract Ascorbic acid is not oxidized (thermally) by ferric salts in oxalic acid solution. When ferric salts in oxalic acid solution are irradiated in an atmosphere of nitrogen, ferrous ions are produced; in an atmosphere of air, ferrous ions are produced when the ratio of iron to oxalate excee
Polyphenol oxidase (PPO, EC 1.10.3.2) was puriยฎed to homogeneity from litchi peel yielding a single protein with a molecular weight of about 75.6 kD by Sephadex G-100 gel ยฎltration, and a 108fold puriยฎcation of PPO achieved. The enzyme was determined to be composed of two similar subunits. Glutathio
The yield of itaconic and citraconic acids obtained by laboratoryscale pyrolysis of anhydrous citric acid can be markedly increased by var~ous catalysts. The best catalyst of those examined was K,HPO,, which, at 5% of the citric acid used, increased the yield of mued acids from 267L to 64O& theoreti
