Abstract The reaction schemes suggested earlier for thermal transformation of glycine into amino acids and carboxylic acids are considered in detail. Close analogy with some wide-spread biochemical reactions of amino acids is observed. The pathway suggested has some common stages with the tricarboxylic acid cycle and other metabolic processes. The possible role of α-imino or α-keto acids as prebiological analogs of pyridoxal-phosphate-containing enzymes is discussed. The thermal transformations of glycine under primitive Earth conditions could be considered as evolutionary precursors of some present-day metabolic pathways.
