4. For experimental details concerning ion exchange chromatography and analysis of fractions, see ref.3. Homoarginine was collected between 10 and 12 l of eluant.
5. The determination of the hydroxy amino acids is sensitive to variation, since these compounds are partially converted to γ-lactones, even under slightly acidic conditions. The concentrations given in the Table have, therefore, to be regarded as approximate values.
