Four Organic Compounds: Carbohydrates Lipids Proteins Nucleic Acids Why organic?

Carbohydrates Polymer Monomer monosaccharide Function body’s primary (Macromolecule) Carbohydrates Monomer monosaccharide Function body’s primary source of energy Examples glycogen (animals); starch (plants) cellulose (plant cell wall) Diagram glucose molecule C6H12O6 1: 2: 1 Ratio Elements: C,H,O

Three Types of Carbohydrates: Monosaccharide – “mono” means one a single sugar Disaccharide – “di” means two two sugars Polysaccharide – “poly” means many sugars

Lipids Polymer Monomer fatty acids & glycerol Function (Macromolecule) Lipids Monomer fatty acids & glycerol Function long term energy storage insulation (conserves heat) Examples fats, oils, waxes, steroids, cholesterol phospholipids (cell membrane) Diagram Elements: C,H,O

Common Lipid Structures Phospholipid Triglyceride Saturated (solid lipid) Unsaturated (liquid lipid)

needed for growth & repair Polymer (Macromolecule) Proteins Monomer amino acids Function needed for growth & repair Examples enzymes, hemoglobin, collagen, muscle, hair, nails, hormones, antibodies Diagram = Polypeptide Chain peptide bond Elements: C,H,O,N

Polypeptide Chain Polypeptide Chain = Chain of Amino Acids = Protein (amine group) Peptide bonds = bonds between amino acids

Protein Structure

stores genetic information & helps make proteins Polymer (Macromolecule) Nucleic Acids Monomer nucleotides Function stores genetic information & helps make proteins Examples DNA, RNA Diagram Nucleotide: Elements: C,H,O,N, P
