Answer: You interconvert any two groups on the chiral carbons. Explanation: For example, the structure of 2-brombutane is. We can convert this to its enantiomer by interchanging any two groups. We often interchange the groups on the wedges and dashes, as below. It is not immediately obvious that these are mirror images of each other. If we rotate the top structure 180 Â° about the axis and put it below our original structure, we get
In general, the optimum, long-term storage temperature for processing potatoes is approximately 45Â° F. For fresh market potatoes, a temperature of 40Â° F. is recommended. Seed potatoes may be stored at slightly lower temperatures (38Â° to 40Â° F.) for better weight loss and sprout control.
1 Pantry time shown is for storage at normal room temperature â if stored in cool (50-60Â° F) dark area, sweet potatoes will last about 1 month. 2  Store sweet potatoes in a loosely covered bag to allow for air circulation. 3  Do not refrigerate raw sweet potatoes, as doing so can alter their taste and flavor during cooking.
