Summary Dicarboxylic diamino acids, monocarboxylic diamino acids and hydroxyamino acids were synthesized in further research on the action of ultraviolet rays on diluted solutions of inorganic nitrogen compounds and ternary organic substances. It is shown that hydroxyamino acids are formed by recombination of OH radicals from H 2 O 2 with amino‐group‐containing radicals from primary amino acids. It is also shown that α, δ‐diaminoadipic acid, arising by recombination of amino‐group‐containing radicals from aspartic acid, furnishes ornithine by further photochemical decarboxylation. The mechanism of formation of hydroxyamino acids is thus elucidated.
