BIOMOLECULES

3. Monomeric unit of nucleic acids consisting of sugar, phosphate and nitrogenous base.
5. Loss of the native three-dimensional structure of a protein due to factors such as heat or extreme pH.
10. Storage polysaccharide of animals, especially abundant in liver and skeletal muscles.
11. Product formed when two amino acids are linked through a peptide bond.
12. Biological catalyst that increases the rate of a biochemical reaction without being consumed.
13. Non-protein organic or inorganic component required for the activity of many enzymes.
16. Complete, catalytically active enzyme consisting of apoenzyme and its required non-protein component.
18. Six-carbon monosaccharide that is an important respiratory substrate.
20. Nitrogenous base found in DNA and RNA; it is a purine.
21. Organic molecule containing amino and carboxyl groups that serves as the basic unit of proteins.
22. Major class of biomolecules made up of amino acids and having diverse structural and functional roles.

1. Polysaccharide forming the major structural component of plant cell walls.
2. Nitrogenous base belonging to the double-ring group of bases.
3. Class of biomolecules that includes DNA and RNA.
4. Pyrimidine nitrogenous base present in both DNA and RNA.
6. Pyrimidine base found in DNA that pairs with adenine.
7. Organic non-protein component of an enzyme, often derived from vitamins.
8. Disaccharide commonly known as table sugar, composed of glucose and fructose.
9. Storage polysaccharide characteristic of plants and composed of glucose units.
10. Monosaccharide that, along with glucose, forms lactose.
11. Polymer formed by linking many amino acids through peptide bonds.
14. Ketohexose monosaccharide commonly found in fruits and honey.
15. One of the two classes of nitrogenous bases found in nucleic acids, including cytosine, thymine and uracil.
16. Chemical process in which a compound is broken down by addition of water; important in digestion of biomolecules.
