Across
- 4. polar and charged molecules that are attracted to water
- 5. type of covalent bond where electrons are equally shared
- 7. CHONS; consists of polypeptides folded into a 3D shape; shape determines function
- 9. CHO; monomers = monosaccharides (simple sugars); polymers = polysaccharides; serves as fuel in cellular respiration and building blocks for amino acids
- 10. hydrogen bonding between water molecules and the solid surfaces surrounding them
- 13. chemical group attached to the carbon skeleton that participate in chemical reactions
- 14. type of bond between two nonmetals; electrons are shared
- 15. macromolecule composed of glycerol and fatty acids linked via ester linkages; includes fats, phospholipids, steroids, and waxes
Down
- 1. the capacity of water molecules to resist coming apart from one another when placed under tension
- 2. synthesis reaction that bonds two monomers with the loss of H2O
- 3. type of bond between ions of opposite charges; electrons are donated
- 4. reaction that breaks the bonds in a polymer by adding H2O
- 5. monomers = nucleotides / nitrogenous bases (A, G, C, T); polymers = DNA / RNA; function is to store, transmit and scpress hereditary information
- 6. type of covalent bond where electrons are unequally shared
- 8. nonpolar molecules that are not attracted to water
- 11. type of fatty acid without double bonds between carbons
- 12. type of fatty acid with one or more double bonds
