Mnemonic to remember monosaccharides and disaccharides

Note:
- To form dissacharides, glucose is involved in all 3 reactions.
- Galactose and lactose are obviously in one reaction.

To help you with memorising, I suggest using Mnemonics:
GGM: Go Grand Ma! - Glucose + Glucose --> Maltose
GFS: Go Father Son! - Glucose + Fructose --> Sucrose
GGL: Go Good Luck! - Glucose + Galactose --> Lactose

What are Mnemonics? Read the following links:

Try coming up with your own Mnemonics for other information, be it for your science or humanities subjects! :)

The one thing some people have been waiting for!

A student was asked to identify the two compounds in each of the three test tubes,
X, Y, and Z. The table above shows the results of the student's tests.


Which of the following statements are true?
A Glucose and starch had been placed in tube Z.
B Albumin and starch had been placed in tube Y.
C Albumin and oil had been placed in tube X.
D Starch and oil had been placed in tube Y.

Answer:
D

Note:
Sodium hydroxide + copper sulphate is actually biuret test. Test for presence of proteins.
Ethanol + water is actually ethanol emulsion test. Test for presence of fats.
