WGU C785 unit 2 COMPLETE SOLUTION

WGU C785 unit 2 COMPLETE SOLUTION 1. Hydrogen bond: Weak bond interaction Between two molecules 2. amino group: Consists of hydorgen and nitrogen atoms (-NH3+) 3. macromolecules: A giant molecule in a living organism formed by the joining of smaller molecules: a protein, carbohydrate, or nucleic acid. 4. polymer: a long molecule consisting of many similar or identical building blocks linked by covalent bonds 5. Amino acid: Amino group + Carboxylic acid + R group = Amino acid 6. carboxyl group: A -COOH group, found in organic acids. Coo-, O=C-O- 7. Four classes of biological macromolecules: Proteins, carbohydrates, nucleic acids, lipids 8. SPONCH: Sulfur phosphorous oxygen nitrogen carbon hydrogen 9. polymer: a long molecule consisting of many similar or identical monomers linked together by covalent bonds. 10. R group: a functional group that defines a particular amino acid that makes it a specific protein (20 amino acids) aka side chain 11. Catalyst: Speed up chemical reactions but remain unchanged by the reaction. 12. monomers: repeating units that serve as the building blocks of a polymer 13. enzymes: specialized macromolecules that speed up chemical reactions in cells 14. alpha carbon: the central carbon atom of each amino acid 15. Atomic number: number of protons 16. atomic mass: number of protons plus number of neutrons 17. dehydration synthesis: a chemical reaction in which two mole covalently bonded to each other with the removal of a water molec 18. amino acid backbone: The structure comprised of the amino group, carboxyl group with a central alpha carbon atom. 19. dehydration reaction: A chemical reaction in which two molecules covalently bond to each other with the removal of a water molecule. 20. Ionic bond: formed when two oppositely charged ions attract 21. Hydrophobic: non polar, afraid of water 22. Disulfide bond: double (di) bond between two Sulfur (sulfide) a teine side chains. They stabilize tertiary and quaternary structures o 23. carbohydrates: Organic compounds composed of carbon, hydrogen, and oxy- gen in a ratio of one carbon atom to two hydrogen atoms to one oxygen atom. They exist as monosaccharides, disaccharides, and polysaccharides. 24. protein:
