[chemie] Benedictreagens

Ik had een vraagje :

Wat is de exacte werking van Benedict-reagens als indicator voor glucose? Wat is de reactie die hierbij hoort?

Merci

Re: [chemie] Benedictreagens

In Benedict's test, the mixture needs boiling. [88-3-(a)-(iv)]  

The Benedict's test is a test for reducing sugar (NOT for the presence of glucose). [92-3-(a)-(iv)][94-1-(a)-(i)][2000-4-(a)-(i)]  

The amount of precipitate formed in Benedict's test can be used to compare the amount of reducing sugars present.
