=Carbohydrate= A carbohydrate molecule is a long chain of monosaccharides connected together. Each monosaccharide (glucose) is a ring shape and contains the elements C, H and O in a 1:2:1 ratio. Functions: Quick Energy and Structures such as Cell Walls in Plants. Also can be used as long-term energy in animals in Glycogen.

=Proteins= A protein molecule is a long chain of amino acids connected together with peptide bonds. Each of the 20 different amino acids is unique but all contain the basic elements C, H, O and N. The sequence of amino acids determines the final folding pattern of the protein and shape determines the function. Functions: Cell Structures (Muscles), Enzymes, Antibodies

=Lipids= A triglyceride molecule is a large molecule consisting of three fatty acid chains connected to a glycerol molecule. Each fatty acid contains long chains of C atoms saturated with H atoms. Overall the molecule contains C, H and a little bit of O. Functions: Membranes, Insulation, Protection and Hormones

=Nucleic Acids= A DNA molecule is a double-helix containing two chains of nucleotides connected together with hydrogen bonds. Each nucleotide contains a phosphate, deoxyribose sugar and a nitrogen base. The nitrogen base varies from A, T, G or C. A always connects with T and G with C in the middle. The sugar and phosphates repeat to form the back bone of both sides of the double-helix. Functions: Nucleic acids function as keepers of the genetic information of the organism in each cell and also serve as the molecules that transfer the information into protein molecules.
