alpha
oh group down
beta
oh group up
conpared to saturated fatty acids, fatty acids with a cis carbon-carbon double bonds
have lower melting points because cis carbon bonds don not allow for good packing
True or false? d glucose and l glucose are enantiomers
true
C=O with an H
Aldehyde = AL ending
C=O OH
= oic acid ending
N with h and side groups
Amine ending
