Chemistry and Metabolism of
Biomolecules
1
, Biomolecules
Biological molecule – molecules present in (produced by)
living organisms
Large – macromolecules
Small – metabolites
Biochemistry and Molecular biology study biomolecules
and their reactions
Organic compounds – O, H, C, N
2
, Metabolism
Set of life-sustaining chemical reactions in organisms
The three main purposes of metabolism are:
conversion of food to energy to run cellular processes;
conversion of food/fuel to building blocks for proteins, lipids,
nucleic acids, and some carbohydrates; and
elimination of nitrogenous wastes
3
, CARBOHYDRATES
