Biology
Across
- 1. a substance that has a molecular structure consisting chiefly or entirely of a large number of similar units bonded together, e.g., many synthetic organic materials used as plastics and resins.
- 2. any of a large group of organic compounds occurring in foods and living tissues and including sugars, starch, and cellulose. They contain hydrogen and oxygen in the same ratio as water (2:1) and typically can be broken down to release energy in the animal body.
- 6. acid a complex organic substance present in living cells, especially DNA or RNA, whose molecules consist of many nucleotides linked in a long chain.
- 7. a molecule containing a very large number of atoms, such as a protein, nucleic acid, or synthetic polymer.
- 10. a molecule that can be bonded to other identical molecules to form a polymer.
- 12. acid deoxyribonucleic from a blend of deoxyribose and nucleic acid.
- 14. any of a class of sugars whose molecules contain two monosaccharide residues.
Down
- 1. a carbohydrate whose molecules consist of a number of sugar molecules bonded together.
- 3. acid a simple organic compound containing both a carboxyl and an amino group.
- 4. the fundamental and distinctive characteristics or qualities of someone or something, especially when regarded as unchangeable.
- 5. a simple sugar that is an important energy source in living organisms and is a component of many carbohydrates.
- 8. any of the class of sugars (e.g., glucose) that cannot be hydrolyzed to give a simpler sugar.
- 9. a hexose sugar found especially in honey and fruit.
- 11. any of a class of organic compounds that are fatty acids or their derivatives and are insoluble in water but soluble in organic solvents. They include many natural oils, waxes, and steroids.
- 13. any of a class of nitrogenous organic compounds that consist of large molecules composed of one or more long chains of amino acids and are an essential part of all living organisms, especially as structural components of body tissues such as muscle, hair, collagen, etc., and as enzymes and antibodies.
