Biochemistry & Medicine • Biochemistry can be defined as the science concerned with the chemical basis of life. • Biochemistry can be described as the science concerned with the chemical constituents of living cells and with the reactions and processes they undergo. A reciprocal relationship between biochemistry & medicine • Normal biochemical process are the basis of health. • The Aim of biochemistry is to describe & explain, all chemical processes of living cells. • Most & perhaps all disease has a biochemical basis. Water • Water plays a central role in the chemistry of all life • The chemical properties of water are related to the functions of biomolecules, entire cells, and organisms 4 The Water Molecule is Polar • Important properties of water arise from its angled shape • o Angle of 104.5 between two covalent bonds • Polar O-H bonds due to uneven distribution of - + charge (oxygen (d), hydrogen (d )) • Angled arrangement of polar bonds creates a permanent dipole for a water molecule 5 (a) Space-filling structure of water (b) Covalent bond angle of water 6
