BSC 1010 Exam 2
Carbon atoms form - *answers * four covalent bonds with other atoms, allowing them to make
structurally complex molecules.
Organic chemistry - *answers * study of carbon.
chemistry of organic molecules is determined largely by - *answers * the number and location
of functional groups
functional groups - *answers * small groups of atoms with specific chemical properties.
When functional groups attach to a larger molecule.... - *answers * They give their properties to
the larger molecule.
Isomers - *answers * different compounds that have the same molecular formula because their
bond is not the same.
Isomers matter because - *answers * Nexium (drug esomeprazole for acid reflex)
Prilosec (drug omeprazole for acid reflex over the counter)
Both are isomers but one stays in the body long and is less effective but gives the option.
Macromolecules - *answers * large molecules AKA biomolecules
Four types of macromolecules - *answers * carbohydrates, lipids, proteins, nucleic acids
Macromolecules are formed by - *answers * condensation reactions
(Covalently combining smaller molecules to form larger, more complex molecules)
, BSC 1010 Exam 2
Polymers - *answers * chains of smaller repeating subunits or residues called monomers)
Carbohydrates, nucleic acids, and proteins. Lipids are NOT.
Lipids do not form polymers but they do form - *answers * aggregates
Can lipids dissolve in water - *answers * No, they are hydrophobic and nonpolar covalent
bonds.
Lipids contain mostly - *answers * C—C and C—H nonpolar bonds, which have high chemical-
bond energy.
Triglycerides - *answers * three fatty acids and one glycerol. saturated or unsaturated.
Saturated fatty acid - *answers * all bonds between carbon atoms are single; they are saturated
with hydrogens; pack together tightly—solid at room temperature
Unsaturated fatty acids: - *answers * one or more double bonds between carbons; causes kinks
in the chain and prevents molecules from packing together tightly; liquid at room temperature.
Melting temperature - *answers * determined by size and how closely the molecules pack
together
Fatty acids are amphipathic - *answers * have a hydrophilic end and a long hydrophobic tail.
Triglycerides are primarily - *answers * hydrophobic
