Peligot distinguishes glucose and sucrose (not by name)

By starch sugar and regular sugar. 

Reviewers of this article suggested glucose as a name. 

In a following memoir, Peligot gave a detailed description of his results on the nature and chemical properties of sugars (Peligot, 1838a); this memoir was enthusiastically reviewed by Dumas, Louis-Jacques Thénard (1777-1857), Joseph-Louis Gay-Lussac (1778-1850), and Jean-Baptiste Biot (1774-1862), who thought that it was of a such high quality that the Académie should consider publishing in its Recueil des Savans Étrangers (Dumas et al., 1838). An interesting point in the report is the suggestion that since the sugar contained in raisins, starch, honey, and urine of diabetics, has the same composition and properties, it be named glucose (from the Greek γλευζοσ, must, sweet wine).
