Macromolecules Macromolecule (Polymer) Monomers (Small Units) Function Key Notes Proteins (Polypeptides) Amino Acids made of 1 common group 1 side group (?R? group Cell membrane All of them contain proteins Make enzymes to help chemical reactions Make antibodies Make up non-steroid based hormones Proteins make molecules (Ex: chair, nail) THINK: Proteins= membranes, enzymes, antibodies, non-steroid hormones, structural molecules,??MEANS? Ex=animal products and enzymes Protein shape matters Different Shapes = Different Jobs Proteins fold and twist into 3-D shapes Proteins do their jobs because of their shape Wrong Shape = No Job (denaturing) Caused by changes in ph. and or temp. Unfold Shape = No longer working ex= animal products, enzymes Carbohydrates
