Biochemistry (8,608 Books)


Biochemistry, sometimes called biological chemistry, is the study of chemical processes in living organisms. Biochemistry governs all living organisms and living processes. By controlling information flow through biochemical signalling and the flow of chemical energy through metabolism, biochemical processes give rise to the incredible complexity of life. Much of biochemistry deals with the structures and functions of cellular components such as proteins, carbohydrates, lipids, nucleic acids and other biomolecules although increasingly processes rather than individual molecules are the main focus.

It is genetically transmitted as an autosomal recessive trait and principally determined by a gene located on the sixth chromosome near the A locus of HLA system. This definition, which does not imply substantial iron overload and - even less the existence of liver damage, covers all the territory between the unexpres...

Excerpt: Inhalation of mercury vapor is the most important route of uptake for elemental mercury. Approximately 80% of inhaled mercury is retained. Oxidation of elemental mercury (HgE) to divalent mercury (Hg++) is a critical event. Divalent mercury is much less likely to cross cell membranes. The oxidation of elemental mercury to divalent ionic mercury takes place very quickly after absorption, but some elemental mercury remains dissolved in the blood long enough to be ...
