300
the fundamental component of macromolecules, can form 4 bonds
What is carbon?
300
Describe the two types of covalent bonding

nonpolar-shared electrons equally
300
reason why coastal areas have fairly moderate temperatures
What is water's high heat capacity
300
“aliphatic”
Successive bonds b/t carbon atoms
may be branched or unbranched
depends on carbon arrangement
What is hydrocarbon chains
300
difference between saturated and unsaturated fat
sat- solid @ room temp, has no DB
unsat- liquid @ room temp, atleast 1 DB
400
caused by the distribution of electrons asymmetrically that create "hot-spots" of charges; requires close proximity
What is Van Der Waals reactions?
400
type of bond that sustains water and stabilizes proteins or DNA
What is hydrogen bonding?
400
two properties that moves water in plant stems
What is adhesion and cohesion?
400
“aromatic”
Usually includes double bonds
Incorporation of these in many biological molecules
