Term
organic compound
Definition
made primarily of carbon atoms, forms four covalent bonds with atoms of other elements, tends to bond with itself
Term
functional groups
Definition
clusters of atoms, influence the characteristics of the molecules they compose and the chemical reactions the molecules undergo
Term
monomers
Definition
carbon compounds made from smaller, simpler molecules
Term
polymer
Definition
a molecule that consists of repeated, linked units
Term
macromolecules
Definition

large polymers

example: lipids, carbohydrates, proteins, and nucleic acids

Term
condensation reaction
Definition
monomers link to form polymers through this chemical reaction, each time a monomer is added to a polymer a water molecule is released
Term
hydrolysis
Definition
water is used to break down a polymer, the reverse of a condensation reaction
Term
adenosine triphosphate (ATP)
Definition
makes energy availible to cells, stores large amounts of energy
Term
carbohydrates
Definition
organic compounds composed of carbor, hydrogen, and oxygen in a ration of 1C:2H:1O, serve as either a source of energy or structural material
Term
monosaccharide
Definition

monomer of carbohydrate, simple sugar, ratio 1:2:1

examples: glucose, fructose, and galactose

Term
disaccharide
Definition
two monosaccharides combine in a condensation reaction to form a double sugar
Term
polysaccharide
Definition
complex molecule composed of three or more monosaccharides
Term
proteins
Definition
organic compounds composed mainly of carbon, hydrogen, oxygen, and nitrogen; formed from the linkage amino acids
Term
amino acids
Definition
monomers, form proteins
Term
peptide bond
