Tests for Proteins, Fats, Sugars, Starch, and Vitamin C:
Protein (Biuret Test): Add Biuret solution. If the sample turns purple, protein is present.
Fat (Emulsion Test): Mix with ethanol, then add water. If a white layer forms, fat is present.
Reducing Sugars (Benedict’s Test): Add Benedict’s solution and heat. If the color changes to green, yellow, orange, or red, reducing sugar is present.
Starch (Iodine Test): Add iodine solution. If it turns blue-black, starch is present.
Vitamin C (DCPIP Test): Add the sample to DCPIP. If the solution turns colorless, vitamin C is present.

Role of Hydrolysis in breakdown of large molecules - Hydrolysis plays a crucial role in the breakdown of large biological molecules into smaller, more manageable units. It is a chemical reaction where a water molecule (H₂O) is used to break the bonds between subunits (monomers) in a larger molecule (polymer).
Role of Condensation in Building Large Molecules:
Condensation is when small molecules join together to make larger ones, while releasing water. This is how proteins, carbohydrates, fats, and DNA are built.
Color Change in a Positive Test for Reducing Sugar:
When testing for reducing sugars, the solution changes from blue to green, yellow, orange, or red, depending on how much sugar is present.
Test for Non-Reducing Sugars:
First, boil the sample with acid to break it down, then neutralize the acid. After that, repeat the Benedict’s test. If the color changes, non-reducing sugars (like sucrose) were present and have been broken into reducing sugars.
