Macromolecules Macromolecules The 4 major macromolecules are proteins, lipids, carbohydrates, and nucleic acid Carbon is the key atom in all macromolecules Dehydration synthesis is a process that removes water from two subunits to join them together to form a polymer Macromolecule Subunit (monomer)+subunit (monomer)+subunit (monomer) + … =polymer subunits can be identical can be different carbohydrates, proteins, lipids, nucleic acids Proteins Amino acids Protein=AA+AA+AA+AA+… 20 different amino acids components carbon atom carboxyl group amino group R group (varies) Polypeptide Protein denaturation Extreme heat Strong acids Strong bases Ionizing radiation Extreme cold Harsh chemicals Denaturation of Protein Carbohydrates Carbohydrate structure
