Carbohydratesare sugars, or long chains of sugars. An important role is to store energy. Short-term energy storage. Structural component of cell membrane. Primary energy source of energy for the body Carbon (C), Hydrogen (H), Oxygen (O) (1:2:1 ratio) Energy Value: 4 kilocalories per gram.
proteinsCarbon (C), Hydrogen (H), Oxygen (O), Nitrogen (N) 4 kilocalories per gram Transport molecules in and out of the cell. Control the speed of chemical reactions. (enzymes) Used for growth and repair of body tissues. Contributes to immunity and fighting diseases. Provides structural support in the form of hair and nails.
lipids Long term energy-storage. Insulates your body. Makes up most of our cell membranes. Carbon (C), Hydrogen (H), Oxygen (O) 9 kilocalories per gram (most energy-dense!)
nucleic acidsTransfers genetic information (RNA). Holds the instructions to make proteins (DNA) Carbon (C), Hydrogen (H), Nitrogen (N) and Phosphorus (P)
Monosaccharides are the monomers of carbohydrates. also, simple sugar
Disaccharides2 monosaccharides examples are sucrose, lactose, and maltose
polysaccharides10 or more monosaccharide units which form complex sugars. examples are starch, glycogen, cellulose, and chitin.
amino acids The monomers of proteins. there are 20 different types of amino acids.
polypeptidethe combination of amino acids forming a protein.
fatty acids the monomer of lipids.
Nucleotidesthe monomers of nucleic acids
DNAA polymer of nucleic acids that holds the instructions to make proteins.
RNAA polymer of nucleic acids that transfers genetic information
Purines Adenine and Guanine
Pyrimidines Thymine and Cytosine
Purines and Pyrimidines are the 2 types of nitrogen bases in a nucleotide which make up to 4 different nucleotides.
Dehydration Synthesis The process of combination of two molecules with the elimination of water molecules 
Hydrolysisis a process in which macromolecules are split into monomers by adding water.
