Biochemistry

Biochemistry, study of the chemical substances and processes that occur in plants, animals, and microorganisms and of the changes they undergo during development and life. It deals with the chemistry of life, and intrinsically it draws on the techniques of analytical, organic, and chemistry, also as those of physiologists concerned with the molecular basis of important processes. All chemical changes within the organism either the degradation of drugs, generally to realize necessary energy, or the build-up of complex molecules necessary for all times processes are collectively termed metabolism. These chemical changes depend upon the action of organic catalysts referred to as enzymes, and enzymes, in turn, depend for his or her existence on the genetic apparatus of the cell. It’s not surprising, therefore, that biochemistry enters into the investigation of chemical changes in disease, drug action, and other aspects of drugs, also as in nutrition, genetics, and agriculture.
