An amide moiety could be superimposed on a model of dihydroxyacetone phosphate.
"The active ingredients that cause tanning to occur, dihydroxyacetone and erythrulose, are chemicals with very unpleasant odors," warns Brattin.
Most tans contain dihydroxyacetone (DHA) which reacts with the amino acids present on the skin's surface to turn it brown.
A lesser known fact is that some self tanning agents contain compounds DHA (dihydroxyacetone) and riboflavin that protect the skin from visible light damage.
According to a panel of medical experts, the active chemical used in spray-on tans -- dihydroxyacetone (DHA) -- can potentially damage one's DNA and cause genetic alterations.
