Concept explainers
Interpretation:
The pro-R or pro-S hydrogen removed from citrate during the dehydration in step 2 of the citric acid cycle.
Concept introduction:
A molecule is said to be pro chiral, if it can be converted from achiral to chiral a single chemical step.
For instance, an unsymmetrical
Which enantiomer of 2-butanol is produced depends on which face of the planar carbonyl undergoes reaction to distinguish between the possibilities, the stereo chemical description Re and Si (announced ‘ray’ and ‘sigh’) are used.
The concept of this designation is as follows: Rank the three groups attached to the trigonal, sp2 hybridized carbon according to the conventional Cahn-In gold-Prelog (CIP) system and imagine curved among from the highest to second highest, to third highest ranked substituents.

- The dehydration of citrate to yield cis-aconitate, a step in the citric acid cycle, involves the pro-R “arm’’ of citrate rather than the pro-S arm. Which of the following two products is formed?arrow_forwardLinoleic acid is shown below. What makes this fatty acid particularly susceptible to autoxidation? 1. The red CH bond has a low bond dissociation energy because it is doubly allylic. 2. The red CH bond has a high bond dissociation energy because it is doubly allylic. 3. The red CH bond is the most accessible to reaction with O2 because it is the least sterically crowded CH bond. 4. Both 2 and 3.arrow_forwardwhat is the heat combustion of C2H5OH at 25C?arrow_forward

(c) Each atom or group attached to a ring-junction carbon (i.e., carbons a -e) is in a trans or axial position. Because of this the tetracyclic ring system is mostly flat. (d) Cholesterol is used to synthesized vitamin D, bile acids, sex hormones, and adrenocorticoid hormones. (e) Cholesterol is not found in the cell membranes of animals.arrow_forward
- Digitalis is a preparation made from the dried seeds and leaves of the purple foxglove, Digitalis purpurea, a plant native to southern and central Europe and cultivated in the United States. The preparation is a mixture of several active components, including digitalin.
