The nucleoside breakdown products ribose-1-phosphate (R1P) and deoxyribose-1-phosphate (dR1P) can be used to produce energy during oxidative or mitochondrial stress to minimize or delay stress-induced damage. Two steps connect these nucleoside breakdown products to central carbon metabolism in mammals. In the second step, deoxy-ribose5-phosphate (dR5P) is cleaved to glyceraldehyde-3-phosphate (GA3P, an intermediate in glycolysis) and acetaldehyde (CH3CHO) by deoxyribose-phosphate aldolase (DERA) (Salleron et al. 2014).
