How many chiral centers does epinephrine have
WebMoreover, it is possible for a molecule to have a center of chirality that sits in a position that does not correspond to an atomic center (and thus, a stereocenter). This occurs in the case of 1,3,5(,7)-substituted admantanes (e.g., (1 S ,3 R ,5 R ,7 S )-3-methyl-5-phenyladamantane-1-carboxylic acid shown in the side box). Web• Therefore, a molecule with 2 stereocentres will have up to 2n = 22 = 4 possible stereoisomers (n = the number of stereocentres). Compounds with n chiral centres will have a maximum of 2n stereoisomers. • The sugar D-glucose, shown below, belongs to a family of sugars known as the six-carbon aldehyde sugars. Its structure is shown below.
