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.
If you keep potatoes in the fridge they should not be stored at temperatures below 7 Â°C (45 Â°F). If, that is, you intend to use them for roasting for frying. At lower temperatures the starch in the potato breaks down giving a burnt look and a bitter taste after roasting.ccording to Keeping Food Fresh by Janet Bailey: Some foods need temperatures warmer than your refrigerator but cooler than your pantry. Fresh potatoes and winter squash for example keep best at a temperature of around 50Â°F. to 55Â°F.
