Question

Do lipids mix with water? Why/why not? From your research on each of these reagents, and reading your lab,fill in the following tables with your predicted outcomes for each macromolecule test you will be performing. Table 1. PREDICTED results for tests for monosaccharides, reducing sugars &complex carbohydrates (note as + or-and the resulting color) Reducing sugar Monosaccharide Starch Carbohydrates Reagent used for testing: Glucose Fructose Lactose Sucrose Starch (example below + orange C&H1206 C&H1206 C12H2201 C12H201 Glycogen CsHioOs Table 2.

Explanation:

Ninhydrin Test is for detecting the existence of amino acids. Ninhydrin is an oxidating agent that leads to deamination of alpha-amino acids and proteins that contain free amino acids. It degrades amino acids into aldehydes, ammonia, and carbon dioxide. The net result is a reduced form of hydrindantin. When ninhydrin condenses with ammonia, hydrindantin produce a bluish-purple pigment known as the Rhuemann’s purple.
