the carbohydrate lactose. 4. Which monosaccharide do starches and cellulose have in common? Starches and cellulose have glucose in common. 5. What is the most abundant organic compound on the Earth? Cellulose is the most abundant organic compound on Earth. 6. What are the structural components of a triglyceride? A triglyceride consists of a glycerol unit attached to three fatty acid molecules. 7. What makes a saturated fat saturated? Saturated fat contains no double bonds. It is saturated with hydrogen. 8. What do all steroids have in common? Steroids all have a system of four linked carbon rings. 9. How do various amino acids differ from one another? Amino acids differ from each other by the chemical identity of the side group. 10. What do a peptide, polypeptide, and protein all have in common? They are all made of amino acids. T&E = 11-20 = ON TEST NOW TOO YOU CAN PRINT THIS 11. Both water-soluble and water-insoluble vitamins can be toxic in large quantities. Our bodies are much more tolerant of the water-soluble ones, however. Why? Water readily passes through our body, which is itself made primarily of water. Excess quantities of the soluble vitamins, therefore, are readily excreted. vitamins, by contrast, tend to build up in nonpolar fatty tissues where they can remain for
