a) draw the amine and carboxylic acid that could react to form these two compunds. Do not add a "+" sign between the amine and the carboxylic acid . ( draw for both piperine and capsaicin)

b) Are the double bonds in piperine and capsaicin cis or trans?

c) name the functional groups that contain the oxgen atoms in these comounds:( choose all matches for both)

piperine: capsaicin: (same as piperine lists )

alcohol

aldehyde

ketone

carboxylic acid

amide

ether

Q2/ In 2002, a new compound URB597, was reported to inhibit the hydrolysis of anandamide and thus prolong tha pain relief rovided by anandamide.

a) Are there any chiral centers in URB597?

b) URB597 is the product of a condensation reaction between an alcohol and one other reactant. Draw the structures of two compunds that "+" sign between the molecules.
