  1. When there are no double bonds between the carbon in the chains, allowing as many hydrogen atoms as possible
    unsaturated fatty acid
  2. Sucrose
    glucose+fructose
  3. When three fatty acid molecules each join to glycerol by an ester linkage
    triacyglycerol
  4. Macromolecules, serve as storage material
    polysaccharides
  5. C2H4
    ethene
  6. Macromolecules that exist as polymers
    polynucleotides
  7. A polymer of glucose that is like amylopectin but more excessively branched
    glycogen
  8. polymers of amino acids
    polypeptides
  9. A large molecule consisting of thousands of covalently connected atoms
    macromolecule
  10. A six-membered ring of carbon and nitrogen atoms
    pyrimidine
  11. A bond between a hydroxyl group and a carboxyl group
    Ester linkage
  12. → a delicate coil held together by hydrogen bonding between every fourth amino acid.
    ------ example?
    • alpha helix
    • ------ CH4
  13. three-dimensional biological polymer constructed from a set of 20 different monomers called amino acids
    protein
  14. This is an organic sulfur compound that contains a sulfur-hydrogen bond ( S-H).
    Thiol
  15. a polymer consisting of many nucleotide monomers; serves as a blueprint for proteins and, through the actions of proteins, for all cellular activities. Two types are DNA & RNA
    polynucleotide
  16. a type of weak chemical bond formed when molecules that don't mix with water come together to exclude the water
    hydrophobic interaction
  17. organic compounds and functional groups that contain a basic nitrogen atom with a lone pair.
    amine
  18. long carbon chain carboxylic acid; vary in length & in the # and location of double bonds;
    fatty acid
  19. A protein may undergo reversible structural changes in performing its biological function. The alternative structures of the same protein are referred to as conformation.
    conformation
  20. → strong covalent bond formed when the sulfur of one cysteine monomer bonds to the sulfur of another cysteine monomer.
    Disulfide Bridges
  21. a polymer of amino acids
    polypeptide
  22. compounds containing a carboxyl group; aka organic acids because they tend to dissociate to release H+
    carboxylic acids
  23. the unique, genetically coded sequence of amino acids within a protein
    primary structure
  24. macromolecules consisting of one or more polypeptide chains folded into a unique 3D shape/conformation
    proteins
  25. →compound with an amino group that can act as a base; the nitrogen, with its pair of unshared electrons, can attract a hydrogen ion, becoming --NH3+.
    amine
