The pure #beta# and #alpha# forms of D-glucose rotate the plane of polarized light to the right by 112Â° and 18.7Â° respectively (denoted as +112 and +18.7). Are these two forms of glucose enantiomers or diastereomers?
A beef roast cooked to medium-rare should have an internal temperature of 145Â°F - 150ÂºF after the resting period, and a roast cooked to medium should have an internal temperature of 150Â°F to 160ÂºF. (See the note below). See Beef Doneness for more information on proper cooking temperatures.o not cover the roast and do not add any liquid (liquid is used for braising, not roasting). Allow the beef to roast at 450Â°F for 45 minutes and then begin checking the internal temperature of the meat with a meat thermometer.
