Document Summary

Define and explain the chemical principles that form the basis of the chemistry of life. Explain the chemistry of hydrophobic and hydrophilic molecules. Describe the chemistry of water and its relationship to biological chemistry and cell biology. Define and explain acids, bases, ph, and buffers in a biological system. Summarize the structure and function of the four major groups of biological macromolecules, highlight- ing similarities and differences. Explain the importance of polymerization to the production of macromolecules. Describe the importance of shape in biological chemistry. Understanding cellular function requires knowledge of cell structure. This is because the struc- ture and function in cells is closely related to the structure of molecules and atoms. Complete transfer of one or more valence electrons. Covalently bound hydrogen has a partial positive charge and attracts electrons of a second atom. H bonds occur in biological molecules (ie. between strands of dna) H bonds determine the structure and properties of water: polarity.
