TLDR
Kinetic studies reveal the enzymatic decomposition of H2O2 to follow first-order kinetics at lower substrate concentrations, and then to deviate from the original linearity, demonstrating mixed- order kinetics.About:

Human placental lipid peroxidation—II. NADPH and iron dependent stimulation of microsomal lipid peroxidation by paraquat
TL;DR: The reaction did not exhibit the initial lag phase suggesting that endogenous membrane-bound antioxidants in human placental microsomes are either absent or present in extremely small quantities.

TL;DR: In addition to the transfer across the placenta,Placenta displays hormonal and xenobiotic metabolism, as well as enzymatic defense against oxidative stress, which must be taken into account in human placental perfusion.
Dissertation
Oxidative Stress and an Alternative Glutathione-dependent Mechanism in the Developmental Toxicity of Methanol
TL;DR: The in vivo teratogenicity of methanol (MeOH) and its underlying molecular mechanisms were investigated, particularly the pathogenic contribution of reactive oxygen species (ROS) and oxidative stress.

Protein Measurement with the Folin Phenol Reagent
TL;DR: Procedures are described for measuring protein in solution or after precipitation with acids or other agents, and for the determination of as little as 0.2 gamma of protein.

A spectrophotometric method for measuring the breakdown of hydrogen peroxide by catalase.
Roland F. Beers,Irwin W. Sizer +1 more
TL;DR: A quantitative, spectrophotometric technique for following the breakdown of hydrogen peroxide has been developed for routine studies of catalase kinetics and appears to give lower values forCatalase activity than do titration techniques.
