What are the four groups of carbon compounds found in

living things?

•Carbohydrates•Lipids•Proteins•Nucleic Acids

Page 3: MACROmolecules BIG molecules. What are the four groups of carbon compounds found in living things? Carbohydrates Lipids Proteins Nucleic Acids

1. Carbohydrates

Made of…CarbonHydrogenOxygen

Examples:glucose fructose lactoseFunction: Provides

Energy

Monomer:MonosaccharideMono = oneSaccharide = sugar

Glucose Molecule

Page 4: MACROmolecules BIG molecules. What are the four groups of carbon compounds found in living things? Carbohydrates Lipids Proteins Nucleic Acids

2. Lipids

Made of…CarbonHydrogenOxygen

Examples:FatsOilsWaxesCholestrolFunction: energy

storage, cell membrane, hormone

Monomer:Triglyceride (three fatty

acids, 1 glycerol)

3. ProteinsLarge molecule made of…CarbonHydrogenOxygenNitrogenSulfur

Examples:hemoglobin (in

blood)Actin & myosin

(muscles)Keratin (hair, nails)

Monomer:Amino acids (20 total)

Function: structure, aid in chemical reaction, immune response

4. Nucleic AcidsMonomer made of…CarbonHydrogenOxygenNitrogenPhosphorous

Examples:DNA (deoxyribo-

nucleic acid)

Function: contains the info cells need to make proteins (“blueprint” for life)

Monomer:Nucleotide (contains

sugar molecule, phosphate molecule, & base molecule)
