What are the 4 macromolecules? • Carbohydrates • Fats • Proteins • Nucleic acids
Carbohydrates • Contain Carbon (C), Hydrogen (H) and Oxygen (O) • 1:2:1 RATIO • Body’s main source of fuel/energy • Produced in chloroplasts during photosynthesis • Broken down in the mitochondria during cellular respiration
Monosaccharides Glucose =C6H12O6
Disaccharide Sucrose = C12H22O11
Polysaccharide = Starch Building blocks are monosaccharides
Fats • Long chains of C, H, and O • Building blocks are fatty acids and glycerol • Storage form of energy • Important in cell membranes, protecting organs, and keeping skin from drying out. ..H..

Fats (cont’d) Saturated-all single bonds, maximum number of hydrogens. Usually solid at room temperature (butter) Unsaturated-contain one or more double bonds. Usually liquid at room temperature (vegetable oil)
Proteins • Contain Carbon, Hydrogen, Oxygen, Nitrogen and Sulfur • Building blocks are amino acids • Main structural material
Nucleic Acids • Contain carbon, hydrogen ,oxygen, nitrogen and phosphorus, • Building blocks are nucleotides • Control of cell • Used as code for building proteins
