Information

3 75 This is the smallest molecule I have found so far. It gives a green color when reacted with alpha-phthaladehyde. Seems to be a metabolite of creatine.
4 131 Another Lactobacillus substance. A small molecule with interesting solubility problems.
Instructions: Enter the number of grams you wish to burn in the top box of the sample. Click on the "Analyze" button at the bottom of the box. Watch the reaction and wait for the result to appear in the bottom box. Write this number down and repeat the experiment with a different number of grams until you have enough data for a graph.
