All L amino acids have an S absolute configuration except L-cysteine, which has the R configuration. L-cysteine is designated as having the R absolute configuration needs to be explained. Concept introduction: Amino acids are so named because they all are weak acids. All amino acids have at least two dissociable hydrogens, (diprotic), and some have three dissociable hydrogens and are triprotic.

Macmillan Learning Cholesterol synthesis begins with the formation of mevalonate from acetyl CoA. This process activates mevalonate and converts it to isopentenyl pyrophosphate. Identify the atoms in mevalonate and isopentenyl pyrophosphate that will be labeled from acetyl CoA labeled with 14C in the carbonyl carbon. Place 14C atoms and C atoms to denote which carbon atoms are labeled and which are not labeled.
