Atoms Elements

HONC PS make up 90% of all living organisms Monomers make up polymers

Monosaccharides Fatty acids Amino Acids Nucleotides

Biological Compounds (polymers) Carbohydrates (CH20) Lipids (CHO) 2x as many H as C, fewer O Proteins (CHONS) Nucleic Acids (CHONP)

Monomer Single unit of a macromolecule Can be linked together to form polymers

MonomerMonomer Monomer Monomer

AKA: sugars, saccharides <the movie was funny, but it had a saccharine ending in

which everyone lives happily ever after>development of saccharin -- an artificial sweetener known

today to many seasoned dieters as Sweet-n-Low. Why are they important?

Polymer: Cellulose

Polymer: Glycogen Animal energy

Monomers (C6H12O6 )Glucose - Photosynthesis Fructose - FruitGalactose – Milk

Same chemical formulaDifferent shape = isomer

Polymer : Starch Plant Energy

C6H12O6

+ C6H12O6

When H2O is created because two monomers are united, this is called a condensation reaction.

The opposite, when water is added to break a polymer apart, it is called hydrolysis.

C12H22 O11

Phospholipids Triglycerides Waxes Steroids

Type of Steroids: Cholesterol

Hormones Androgen

Corticosteroids HGH BGH

Lots of C, twice as much H, very little O Long hydrocarbon chains

Fatty acid (monomer)

Triglyceride (Fats) Saturated or unsaturated Oil (liquid) - E storage Fat (solid) - E storage, insulation, padding

Phosphate

PHOSPHOLIPID

Impermeable to H20, maintains cell integrity.
