Protein Overview Major constituent of most cells (>50% dry weight) Highly sophisticated molecules (or multi- molecular complexes) Extremely large number of unique proteins exist They are polymers folded into specific conformations (shapes) Conformation and functional-group chemistry controls function Made up of 20 different types of amino-acid monomers Proteins define what an organism is, what it looks like, how it behaves, etc. (responsible for most phenotype) You are your proteins!
