Across
- 4. an extensively branched glucose storage polysaccharide found in the liver and muscle of animals; the animal equivalent of starch
- 9. a lipid consisting of three fatty acids linked to one glycerol molecule; also called a triacylglycerol or triglyceride
- 10. the level of protein structure referring to the specific linear sequence of amino acids.
- 13. a polymer (polynucleotide) consisting of many nucleotide monomers; serves as a blueprint for proteins and, through the actions of proteins, for all cellular activities
- 14. the building block of a nucleic acid, consisting of a five-carbon sugar covalently bonded to a nitrogenous base and one to three phosphate groups
- 17. an organic molecule consisting of only carbon and hydrogen
- 18. a structural polysaccharide, consisting of amino sugar monomers, found in many fungal cell walls and in the exoskeletons of all arthropods
- 19. the study of whole sets of genes and their interactions within a species, as well as genome comparisons between species
- 20. a giant molecule formed by the joining of smaller molecules, usually by a dehydration reaction
- 21. a biologically functional molecule consisting of one or more polypeptides folded and coiled into a specific three-dimensional structure
Down
- 1. the sugar component of RNA nucleotides
- 2. a chemical reaction in which two molecules become covalently bonded to each other with the removal of a water molecule
- 3. a long molecule consisting of many similar or identical monomers linked together by covalent bond
- 5. a lipid consisting of three fatty acids linked to one glycerol molecule; also called a fat or triglyceride
- 6. a chemical agent that selectively increases the rate of a reaction without being consumed by the reaction
- 7. one of two or more compounds that have the same numbers of atoms of the same elements but different structures and hence different properties
- 8. one of two or more compounds that have the same molecular formula but differ in the covalent arrangements of their atoms
- 11. a type of lipid characterized by a carbon skeleton consisting of four fused rings with various chemical groups attached
- 12. a macromolecule serving as a catalyst, a chemical agent that increases the rate of a reaction without being consumed by the reaction
- 15. any of a group of large biological molecules, including fats, phospholipids, and steroids, that mix poorly, if at all, with water
- 16. the bonding capacity of a given atom; the number of covalent bonds an atom can form, which usually equals the number of unpaired electrons in its outermost (valence) shell
