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
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)
