Pre-Lab: Protein and Fat Detection
Purpose
The purpose of this lab is to detect both proteins and fats in common foods.
Proteins will be identified by testing with Biuret reagent and fats will be identifying by observing their mark on paper towel.
Watch the following videos to see the experiments in which you will be expected to preform in the lab. Then answer the prelab questions assigned.
