Comments "The largest proportion of cellular N in phytoplankton is bound in protein and free amino acids (>70%), and a detailed study of internal N pools in a strain of marine Synechococcus showed that proteinaceous material contributes between 74% and 84% of total cellular N, whereas the cellular N contained in other organic biomolecules such as pigments and nucleic acids is minor (<3%) (primary source)."
