FAQ
Frequently Asked Questions
No, they are different reagents. Both test for reducing sugars, but Benedict's solution is more stable and uses sodium citrate, while Fehling's uses tartrate.
No, it only tests for reducing sugars (e.g., glucose, fructose, maltose). It will not react with non-reducing sugars like sucrose unless they are first hydrolysed.
It is named after the American chemist and pathologist Stanley Rossiter Benedict, who published the formulation in 1908.
Its primary use is in educational laboratory settings for teaching qualitative biochemistry. Its clinical use for urine sugar testing has largely been replaced by more specific enzymatic or dipstick methods.
