Across
- 3. class of molecules whose defining characteristic is that they do not readily dissolve in water; made of same elements as carbs, but contain much more hydrogen relative to oxygen
- 5. fats in their liquid forms
- 8. larger-scale 3D shape that a protein takes
- 11. fatty acid with two or more double bonds between carbon atoms
- 13. way in which two or more polypeptide chains come together to form a protein
- 15. organic molecules that always contain carbon, oxygen, and hydrogen, and may contain nothing but these; usually contain twice as many hydrogen atoms as oxygen atoms
- 18. branch of chemistry devoted to the study of molecules that have carbon as their central element
- 20. fatty acid with no double bonds between the carbon atoms of its hydrocarbon chain
- 25. molecules that are a combination of lipids and proteins; active in transporting fats throughout the body
- 26. group of atoms that confers a special property on a carbon based molecule
- 27. molecule found in many lipids that is composed of a hydrocarbon chain bonded to a carboxyl group
- 28. complex carbohydrate found in plants; serve as the main form of carbohydrate storage in plants
- 29. charged lipid molecule composed of two fatty acids, glycerol, and a phosphate group
- 30. forms the external skeleton of the arthropods
- 31. complex carbohydrate and primary form of storage in animals
- 33. building block of nucleic acids, consisting of a phosphate group, a sugar, and a nitrogen-containing base
- 34. large, folded chain of amino acids
Down
- 1. structure that proteins assume after folding up
- 2. primary information bearing molecule of life, composed of two linked chains of nucleotides
- 4. polymer of carbohydrates, composed of many monosaccharides
- 6. structural, complex carbohydrate produced by plants and animals; makes up so much of the natural world
- 7. small molecule that can be combined with other similar or identical molecules to make a polymer
- 9. fatty acid with one double bond between carbon atoms
- 10. lipid composed of a single fatty acid linked to a long-chain alcohol
- 12. combination of proteins and carbohydrates; play important roles as cell receptors and some types of hormones
- 14. molecule composed of nucleotides that is active in the synthesis of proteins
- 16. large molecule made up of many similar or identical subunits
- 17. series of amino acids linked in linear fashion
- 19. level of a protein; the sequence of amino acids
- 21. lipid molecule formed from three fatty acids bonded to glycerol
- 22. steroid molecule that forms part of the outer membrane of all animal cells and acts as a precursor for many other steroids
- 23. phosphorus atom surrounded by four oxygen atoms
- 24. building block, or monomer, of carbohydrates, also called simple sugars
- 32. variety of lipid molecules that have four carbon rings as a central element in their structure
