Introduction: Creatine is a naturally occurring organic acid that is absorbed through food such as meat or fish. However, when food intake is low, creatine is produced from glycine, arginine, and methionine in the liver, kidneys, and pancreas. It provides the energy necessary for strenuous muscle contractions and enhances performance during high-intensity exercises. Creatine is an important molecule because it increases aerobic recovery and protein synthesis. Because of this, creatine has been used in dietary supplements and supplements for athletes. In this lab sarcosine and cyanamide will be used to synthesis creatine. The mechanism for this reaction is shown below. Once synthesized an NMR and IR analysis will be conducted on the product. Also the melting point will be determined and the percent yield will be calculated. Procedure and Data/Observations: The procedure for this experiment was taken from the print out. First, 235 mg of sarcosine (2.64 mmol) and 0.5 mL of distilled water were added to a 10 mL round-
