Photo-production of lactate from glyoxylate: how minerals can facilitate energy storage in a prebiotic world.
The reaction of glyoxylate with carbon dioxide to produce lactate is promoted when zinc sulfide is irradiated by ultraviolet light. These results, representing a model for the action of colloidal mineral semiconductors on early Earth, complete a consecutive series that culminates in entry-point molecules of the reductive tricarboxylic acid cycle.
