TLDR
The biochemistry of copper is one book that the authors really recommend you to read, to get more solutions in solving this problem.Abstract:
A solution to get the problem off, have you found it? Really? What kind of solution do you resolve the problem? From what sources? Well, there are so many questions that we utter every day. No matter how you will get the solution, it will mean better. You can take the reference from some books. And the biochemistry of copper is one book that we really recommend you to read, to get more solutions in solving this problem.read more

Noninvasive, infrared monitoring of cerebral and myocardial oxygen sufficiency and circulatory parameters
TL;DR: Observations by infrared transillumination in the exposed heart and in the brain in cephalo without surgical intervention show that oxygen sufficiency for cytochrome a,a3, function, changes in tissue blood volume, and the average hemoglobin-oxyhemoglobin equilibrium can be recorded effectively and in continuous fashion for research and clinical purposes.

The Carbon Dioxide Hydration Activity of Carbonic Anhydrase I. STOP-FLOW KINETIC STUDIES ON THE NATIVE HUMAN ISOENZYMES B AND C
TL;DR: The present kinetic results are interpreted as representing a great specificity of carbonic anhydrase for the binding of its substrate CO2, and it is proposed that the enzyme-catalyzed hydration of CO2 requires, not only water activation by a basic group, but also charge neutralization in the transition state by an electron acceptor function.

Polyphenol oxidases in plants and fungi: going places? A review.
TL;DR: The more recent reports on polyphenol oxidase in plants and fungi are reviewed and many details about structure and probably function of PPO have been revealed, but some of the basic questions raised over the years remain to be answered.

TL;DR: The three-dimensional structure of plastocyanin, a blue or "Type 1" copper-protein, has been determined at a resolution of 2.7 A as discussed by the authors, and it is coordinated by a cysteine thiol group, a methionine thioether group and two histidine imidazole groups.

A site-specific mechanism for free radical induced biological damage: The essential role of redox-active transition metals
TL;DR: In biological systems, there are traces of copper and iron that are at high enough levels to catalyze free-radical reactions, and account for such deleterious processes, and the rate constants of their reduced forms with hydrogen peroxide are sufficiently high to suggest that they might be important mediators of free radical toxicity.
