Protons carry a positive charge, whilst electrons have a negative charge Atomic numbers tell how many protons, therefore how many electrons there are when an atom is electrically neutral Proteins: macromolecules with amino acid subunits The carbon atom in an amino acid bonds to a hydrogen atom and to three other groups of atoms; COOH DNA: located in the nucleus of cells and stores genetic information in the cell. Contains many genes Lipids: energy storage molecules Steroids: has a backbone of four fused carbon rings; testosterone Triglyceride: three-part structure; molecule is nonpolar and carries no charge Carbohydrates: first and foremost function for quick and short-term energy storage Monosaccharide: low number of carbon atoms Glycogen: hexose that our bodies use as an immediate source of energy C6H12O6 Disaccharide: made by joining two monosaccharides together Starch: readily stored forms of glucose up to 4,000 glucose units
