Please, correct answer. Will give ? In the 'H NMR spectrum of acetyl acetone, the height of the integration curve at 3. methylene (-CH2) signal was found to be 10 mm and that of the methine (=CH) signal was 22 mm. Calculate the percentages of the keto and enol forms in the sample.
3. Int 3. In the 'H NMR spectrum of acetyl acetone, the height of the integration curve at methylene (-CH2) signal was found to be 10 mm and that of the methine (-CH) signal was 22 mm. Calculate the percentages of the keto and enol forms in the sample. methyl was 22

Use your knowledge of generic amino acid aminotransferase mechanism to push the arrows for the complete alanine aminotransferase reaction. The alpha-keto acid used is pyruvate; use a generic amino acid.
Draw a mechanism for the following tautomerization. gran on ar HO H2O
Are there answers right? I was having trouble. The left compound was prescribed to my old dog. Unfortunately the internet contains more that one structure (keto vs enol) for the same compound so the absolute configurations listed vary. Remembering that multiple bonds arc interpreted as multiple single bonds to the
