background: copper sulfate ingestion is a relatively popular method for committing suicide in indian subcontinent. it causes a high mortality rate, and so a growing concern has been raised to identify the severe alarming signs suggestive of poor prognosis and to improve treatment approaches. case report: a 22-year-old unmarried man working as a painter was found unconscious at his friend reside...

Aspects of intramolecular light energy and electron transfer will be discussed for three protein cofactor complexes, whose three-dimensional structures have been elucidated by X-ray crystallography: components of light-harvesting cyanobacterial phycobilisomes, the purple bacterial reaction centre and the blue multi-copper oxidases. A wealth of functional data is available for these systems whic...

the interaction of biomolecules with carbon nanotubes (cnts) has generated a great deal ofinterest in the past few years. the interaction between b-form single-strand dna (ssdna) andsingle-walled carbon nanotubes (swcnts) is a subject of intense current interest; however thereare a relatively small number of papers in the literature dealing with interaction of dna andswcnts. in this work we inv...

A change of solvent causes an inversion of the stereochemistry at copper of the chiral Cu(I) complex described herein.

Plastocyanin, a copper protein, was first isolated by Katoh in 1960 from the green alga, Chlorella ellipsoidea, and subsequently from various higher plants.l~,2) The protein is present in the chloroplasts and functions as an electron carrier from cytochrome f to P7OO in the electron transport chain between photosystem II and I.3) The redox reaction of plastocyanin is due to its copper valency c...

In recent years, the demand for copper and nickel has risen world-wide due to their use in printed circuit boards, batteries, application in marine alloys (due to excellent resistance to corrosion by seawater), and a wide range applications in day-to-day life (Doebrich, 2009). Increasing demand for these metals is leading to rapid depletion of high-grade resources. Alternative sources, such as ...

Hemocyanin is a copper-containing protein which occurs in the blood of a number of species of arthropods and molusks. The extent of the reversible combination with molecular oxygen is a function of the partial pressure of oxygen, and like the formation of oxyhemoglobin is affected by changes in acidity and salt concentration. The ratio of combined molecular oxygen to copper is 02:2Cu in all the...
