Concept explainers
To identify: The chiral carbon in the given structure.
Introduction:
The carbon atom that attaches to the four distinct groups is known as “chiral center”. The isomers can be formed because of only chiral center. The isomers differ based on group’s arrangement in structure.
To determine: Whether the structure is (R) or (S) isomer.
Introduction:
The carbon atom that attaches to the four distinct groups is known as “chiral center”. The isomers can be formed because of only chiral center. The isomers differ based on group’s arrangement in structure.
To determine: The other isomer of Propranolol.
Introduction:

- Sodium borohydride (NaBH4) is a potent inhibitor of aldolase. It is known to ONLY inhibit theenzyme when it is complexed with substrate. Treatment of the enzyme alone has no effect.What is the mechanism for this inhibition? Please draw out the mechanism and show how it inhibits this.arrow_forwardShow the fate of the proton on the 4-Oxygen molecule of F-1,6-BP. Please include a drawing showing the electron flow that occurs.arrow_forward1. Which one is the major organic product obtained from the following aldol condensation? O NaOH, H₂O heat A B C D Earrow_forward
- An organic chemist ordered the wrong item. She wanted to obtain 1-hydroxy-2-butanone, butinstead ordered 2-hydroxybutyraldehyde. As a good biochemist, show how the organic chemistcould use biological catalysis to make her desired compound.
