Tollens' reagent (chemical formula ()) is a chemical reagent used to distinguish between aldehydes and ketones along with some alpha-hydroxy ketones which can tautomerize into aldehydes. The reagent consists of a solution of silver nitrate , ammonium hydroxide and some sodium hydroxide (to maintain a basic pH of the reagent solution).
Reducing form of glucose (the aldehyde group is on the far right). A reducing sugar is any sugar that is capable of acting as a reducing agent. [1] In an alkaline solution, a reducing sugar forms some aldehyde or ketone, which allows it to act as a reducing agent, for example in Benedict's reagent.
Unable to resist the call of his former professor Wöhler, Tollens returned to Göttingen in 1872 and there he remained in various positions until he died in 1918. It was during this final time in Göttingen that he started his work on carbohydrates, which yielded structures of several sugars, the Tollens' reagent, and most of his publications.

Travis Hunter won the 2024 Heisman Trophy in the closest vote since 2009. How does the Colorado star's win compare to the voting from that season?
Phloroglucinol is a reagent of the Tollens' test for pentoses. This test relies on reaction of the furfural with phloroglucinol to produce a colored compound with high molar absorptivity. [26] A solution of hydrochloric acid and phloroglucinol is also used for the detection of lignin (Wiesner test).
