I just learnt them today aha idk whether I’ll remember them but I’ll try give something a go now.

Reducing sugars - benedicts - goes from blue to green to yellow to brick red.
To remember: “reducing” means there are separate layers or a decrease so it goes through the colours?

Protein - Biuret - blue to purple
I have nothing to protein but in my head protein is ugly and biuret doesn’t sound great but there’s alliteration.

Starch - iodine - orange to blue/black
To remember: if you ever did the test in like year 7/8 with the onion. ‘Eye’ for iodine (eye-odine) will hurt if it’s in your eyes??

Lipids/fat - sudan - bright red layer (like a layer of fat?”


I have no other ideas of how to remember but maybe my crappy analogies might help haha good luck

this is real dumb but it works for me. BP IS ******** SLow.
BP - biuret proteins
IS - iodine starch
BS - benedicts sugar
SL - Sudan III lipids.



although, it's a shame it's not BT instead of BP since that would make more sense.

Oh lol I have my exam tomorrow aswell must have been thinking the same thing. Quite confused by the anogram the bull s** lol

Update: I understand now I'm quite slow

This is how I fully understand it:

Bip is bs slow
Biuret protein
Iodine Starch
Benedict Sugar
Sudan lipids

I added the bip so I don't get confused between Biuret and Benedict in my frantic brain tomorrow lol
