This document contains a chemistry challenge with questions about the chemical composition of key biomolecules like carbohydrates, lipids, nucleic acids, proteins, and water. It asks students to identify monosaccharides, disaccharides, and polysaccharides. Questions also cover the structures of starch, glycogen, and cellulose, as well as the primary, secondary, tertiary, and quaternary structures of proteins. The challenge examines saturated and unsaturated fats, including that triglycerides have one glycerol and three fatty acids. It asks whether saturated or unsaturated fats are solid at room temperature.
