hydrophobic
4
Q
what is the definition of an isomer?
A
compounds with the same number of atoms of the same elements but different structures and properties
5

structural
cis-trans
enatniomer
6
Q
what is a case study of enantiomers having different properties?
A
the thalidomide tragedy
7
Q
what do the properties of an organic molecule depend on?
A
the arrangement and chemical groups attached to its skeleton
8
Q
what are the chemical groups important to life?
A
hydroxyl - polar carbonyl - found in sugars carboxyl - acts as an acid amino - acts as a base sulfhydrl - can stabilize protein structure phosphate - negative charge methyl - can act as a tag or label (not very reactive) ATP
