What is the molecular formula of this immunosuppressant? How manj' stereocenters are present in FK-506? Determine the maximum number of stereoisomers possible. Identify and label the various functional groups present. Consider the two stereocenters in this structure labeled with asterisks (*). Determine the absolute configuration of each stereocenter. FK-506 has been shown to exhibit moderate solubility in various organic solvents. Is this immunosuppressant expected to be soluble in ethanol (CH3CH2OH)? Consider the carbon atom labeled “1."

- 15-21 Answer true or false. For a molecule with two stereocenters, 22 = 4 stereoisomers are possible. For a molecule with three stereocenters, 32 = 9 stereoisomers are possible. Enantiomers, like gloves, occur in pairs. 2-Pentanol and 3-pentanol are both chiral and show enantiomerism. 1-Methylcyclohexanol is achiral and does not show enantiomerism. Diastereomers are stereoisomers that are not mirror images.arrow_forward15-10 Define the term “stereoisomer.” Name three types of stereoisomers.arrow_forward15-7 Answer true or false. The cis and trans stereoisomers of 2-butene are achiral. The carbonyl carbon of an aldehyde, ketone, carboxylic acid, or ester cannot be a stereocenter. Stereoisomers have the same connectivity of their atoms. Constitutional isomers have the same connectivity of their atoms. An unmarked cube is achiral. A human foot is chiral. Every object in nature has a mirror image. The most common cause of chirality in organic molecules is the presence of a tetrahedral carbon atom with four different groups bonded to it. If a molecule is not superposable on its mirror image, the molecule is chiral.arrow_forward
