what are the 5 types of representation
structural, condensed structural, line angle, ball and stick, and space filling
What is a formal charge?
valence electrons - (nonbonded electrons + .5(bonded electrons))
what is the name of the functional group that looks like a pentagon?
What is organic synthesis?
reacting molecules to make other molecules based around transforing functional groups
where is electronegativity highest at?
the top right of the pierodic table
What is the rule for solubility?
Like dissolves like
What disolves polar molecules? what is an example?
what disolves non polar molecules? what is an example?
When designing drugs what kind of solubility should they be?
hydrophilic enough to be soluble in water but hydrophobic enough to pass through cells
what does hydrophilic and hydrophobic mean?
favors water and nonpolar solvents respectivly
what is the free base?
simply the basic form of the molecule.

how many amino acids are there?
there are 20 naturally occurring amino acids
what is the primary structure of proteins?
the swquence of the amino acids
what are polypeptides?
amino acids that have been linked together by covalent bonds?
what are covalent bonds?
typically irreversible, difficult to break chemical bonds
what is the secondary structure of proteins?
the 3d subunits of a protein (alpha helixes and beta sheets)
what type of 3d units do polypeptides form?
alpha helices and beta sheets (the spiral and the unspiraled versions respectily)
What do tertiary structures refer to?
the whole protein
what is the quaternary structure of proteins
the noncovalent association of two or more proteins
How do drugs deliever there message?
throgh chemical signaling pathways in the body
What are Hormones?
chemical messengers produced by the body's endocrine glands
what are some exampls or the body's endocrine glands?

reduces pain, swelling, fever, heart attack chances
what does NSAID stand for?
Non steriodal anti inflamatory drug
what is an enzyme?
how does Aspirin and other NSAID drugs work?
they block the cyclooxygenase (COX) enzymes.
what does COX (cyclooxygenase) do?
synthesizes hornone like compounds called prostaglandins from arachidonic acid
