Using Chemical Reagents and Indicators to Determine the Presence of Macromolecules Nutrients in Unknown Solutions Abstract: To use chemical reagents to test for simple sugars and starch, proteins, and fats in the multiple procedure lab. Important equipment that was involved in this experiment included the chemical reagents such as Benedict’s reagent and Lugol’s solution for carbohydrates, Sudan IV indicator for lipids and Biuret reagent for proteins because these reagents determined the colour
Background of Study Water is defined as one type of liquid that descends from the clouds such as rain, lakes and also sea. Water is the most important nutrient and play a fundamental roles for all living matter. For example, water supply around 50% of the weight for human and even every living matter (Rozin, Haddad, Nemeroff, & Slovic, 2015). There are around 71% of the earth’s surface was covered by water. Besides, there are eight types of distribution of waters on earth which one of it was groundwater
