Organic nitrogen means nitrogen chemically bound in organic molecules such as proteins, amines, and amino acids; total Kjeldahl nitrogen minus ammonia nitrogen.

Organic nitrogen really means amino acids. Most commonly amino acids used in yeast nutrients are from yeast in the form of yeast extracts or autolyzed yeast. Ideally, one would really like to know the exact composition since some amino acids like proline cannot be used by yeast under anaerobic conditions.
