Acetylcholine is an ester of acetic acid and choline with chemical formula CH 3 CO O CH 2 CH 2 N + (CH 3) 3. This structure is reflected in the systematic name, 2-acetoxy-N,N,N-trimethylethanaminium. Acetylcholine (ACh) was first identified in 1914 by Henry Hallett Dale for its actions on heart tissue.
1 Place pork tenderloin in roasting pan. 2  Roast for 30 minutes. 3  Turn the pork over and roast for another 25 minutes. 4  The pork tenderloin is ready when the internal temperature reaches 145 degrees Fahrenheit (63 degrees Celsius).
Pork is cooked in minutes per pound. So roast a tenderloin at 425 degrees F for 15-20 minutes per pound and grill it over medium coals for 15-25 minutes per pound. The internal temperature should be a minimum of 145 degrees F (the USDA lowered the safe temperature for pork in the summer of 2011).
