Molecules of Life
Monosaccharides
Glucose, Fructose,
Galactose (1 carbon ring)
Disaccharides
Sucrose (2 carbon rings)
Carbohydrates (Sugars and
Starches)
Polysaccharides (3 or more
carbon rings)
Proteins
Amino acids (Building
Blocks) →
Glycogen
Animals: Energy storage
Cellulose
Plants: Cell walls “stiff stuff
in plants
Starch
Plants: Energy Storage
Polypeptide (Chain of
Amino Acids) →
Protein (skin, hair, nails,
muscle, etc.) (Folded Chains
of Polypeptides—Shape is
important to function)
Unsaturated (double
bonds—can take more H)
Fats
Glycerol and 3 fatty acid
chains
Saturated (no double bonds,
max # of H)
Lipids
Nucleic Acids
Steroids
4-fused carbon rings →
Nucleotides (building
blocks) →
Make Nucleic Acids such as
DNA and RNA which carry
hereditary information
Attached functional group
determines identity and
function
Cholesterol, testosterone,
estrogen
