Basic chemistry of a cell Properties of water – – – Life on Earth began in water and evolved there for 3 billion years before spreading onto land. Modern life‚ even terrestrial life‚ remains tied to water. All living organisms require water more than any other substance. Human beings for example‚ can survive for quite for a few weeks without food‚ but only a week or so without water. – – – Water is deceptively simple. It is shaped something like a wide V‚ with its two hydrogen atoms joined

The protozoan intestinal parasite Giardia lamblia lacks mitochondria and the ability to make haem yet encodes several putative haem-binding proteins‚ including three of the cytochrome b5 family. We cloned one of these (gCYTb5-I) and expressed it within Escherichia coli as a soluble holoprotein. UV-visible and resonance Raman spectra of gCYTb5-I resemble those of microsomal cytochrome b5‚ and homology modelling supports a structure in which a pair of invariant histidine residues act as axial

RABIES Abstract: Each year‚ approximately 55‚000 individuals worldwide die from an infection due to the rabies virus. Rabies is a life-threatening disease caused by an RNA virus that is usually transmitted to humans through bites from rabid animals. More recently‚ reports of transmission by means of organ transplantation have been reported. Since human rabies is nearly 100% fatal if prophylactic measures are not followed‚ an increased awareness of who should receive prophylaxis and

Introduction and Chemistry of Life Anatomy: the study of structure or shape of body parts and their relationship to each other. Physiology: the study of function (how the parts work) Levels of structural organization: There is a hierarchy of structural complexity‚ beginning with the simplest or chemical level and culminating with the highest level-the whole organism Chemical level – atoms (and their parts)‚ and combinations of atoms called molecures Cellular level – cells are the basic structural
