Document Summary
Biochem aims to explain bio form and function in chem terms. C, o, n, h are main elements of plant and animal world. 30/90 naturally occurring elements are essential to life. What is true of e. coli is true of the elephant . Biomolecules are compounds or carbon with a variety of functional groups: carbon forms 4 very stable single bonds. Double bonds are shorter and only allow limited rotation: most biomolecules are derivatives of hydrocarbons and have multiple types of functional groups. Cells contain a universal set of small molecules: these are the central metabolites in the major pathways occurring in nearly every cell. Can be polar or charges and are water-soluble. Macromolecules are the major constituents of cells: macromolecules- polymers with molecular weights above 5,000. Polysaccharides: proteins- long polymers of amino acids. Constitute largest fraction (besides water) of a cell. Proteome- sum of all proteins functioning in a given cell.
