I am a biologist after all. Enjoy!
So blue Benedict& #39;s = no reducing sugars present! Try hydrolysing the solution and try again.

Ok, so I love biochemical tests. Let& #39;s do some more.

How about the Biuret test for protein? A lovely purple colour.

Iodine test for starch? Well, it& #39;s sort of orangey-brown when it& #39;s a negative result.

One last one - the emulsion test for lipids. It goes white if fats are present.

And there you go! Science and Benedict all in one. Imagine what quality content you& #39;ll get when I hit 500!
