Ch. 2 Continued Organic Chemistry Recognizing the 4 main classes of organic compounds.

CHON 4 most common elements in living things Carbon Hydrogen Oxygen Nitrogen

Organic Compounds Any compound that has carbon.

4 Classes of Organic Compounds Carbohydrates Lipids Proteins Nucleic Acids

Carbohydrates C 6 H 12 O 6 Used for ENERGY 3 Types –Monosaccharides –Disaccharides –Polysaccharides

Monosaccharide 1 Simple Sugar Ends in –ose Examples: –Glucose –Fructose

Disaccharide Disaccharide Made of 2 simple sugars.

Polysaccharide Made of many simple sugars.

Lipids Made of 1 Glycerol and 3 Fatty Acids Used to STORE energy. Examples –Fats –Oils –Waxes

Saturated vs. Unsaturated Fats Saturated fats contain only single bonds between carbons. Unsaturated fats contain at least one double bond between carbons.

Proteins Chain of amino acids.

Nucleic Acids DNA and RNA Made of nucleotides. Each nucleotide contains –1 sugar –1 phosphate group –1 base

Dehydration Synthesis When molecules combine, water is released!

The End… for now…
