Carbohydrates, Fats and Protein

All carbohydrates, proteins and fats contain the elements oxygen, carbon and hydrogen. Additionally, protein has Nitrogen + Sulphur.

Starch and Glycogen

Simple sugars, amino acids and fatty acids are monomers, which string together to form a complex network known as a polymer such as glucose, proteins and fats.

In the case of carbohydrates, starch and glycogen are large polymer molecules made of glucose.

Protein

In the case of proteins, amino acids are the monomers. Different amino acids bond together to form chains known as peptides. These peptides come together to form proteins such as enzymes.

Fat

As for fats and oils; the most common type of fats are triglycerides

Iodine Test

Biuret Reagent Test

The Biuret Test is done to show the presence of peptide bonds, which are the basis for the formation of proteins. These bonds will make the blue Biuret reagent turn purple.

Ethanol Emulsion Test

The ethanol emulsion test is done to show the presence of
