21. It is unclear if twice as much racemic lipoic acid can replace RLA. 22. Hydrolysis into isoborneol followed by oxidation gives racemic camphor. 23. Deprenyl is a racemic compound, a mixture of two isomers called enantiomers. 24. Optically active BINOL can also be obtained from racemic BINOL by optical resolution. 25. :: Actually, the squigly bond means that the structure is racemic . 26. It exists as two enantiomers and can be obtained as a racemic mixture. 27. A non-racemic mixture of two enantiomers will have a net optical rotation. 28. Racemic and regular PLLA has a low glass transition temperature, which is undesirable.29. Trace amount of acid in water causes hydrolysis to racemic phenylethyleneglycol via aryl cation. 30. Ibuprofen is administered as a racemic mixture.
