Macromolecules are large molecules formed by joining smaller organic molecules together
Lipids Store energy Provide steroids Waterproof coating Molecules made mostly of carbon and hydrogen
Carbohydrates Stores energy Provides structural support Compounds composed of carbon, hydrogen, and oxygen in a ratio of one oxygen and two hydrogen atoms for each carbon atom— (CH 2 O) n
Nucleic Acids Stores and communicates genetic information complex macromolecules that store and transmit genetic information Nucleic acids are made of smaller repeating subunits called nucleotides, composed of carbon, nitrogen, oxygen, phosphorus, and hydrogen atoms
Proteins Transports substances Speeds reactions Provides structural supports Provides hormones A compound made of small carbon compounds called amino acids Amino acids are small compounds that are made of carbon, nitrogen, oxygen, hydrogen, and sometimes sulfur.
