Threonic acid is a sugar acid derived from threose. The l-isomer is a metabolite of ascorbic acid (vitamin C). One study suggested that because l-threonate inhibits DKK1 expression in vitro, it may have potential in treatment of androgenic alopecia. Threonic acid is a sugar acid derived from threose.
