Document Content and Description Below

Student Exploration: Identifying Nutrients Vocabulary: carbohydrate, disaccharide, lipid, monosaccharide, polysaccharide, protein, starch Prior Knowledge Questions (Do these BEFORE using the Gizmo.) ... 1. What are the major types of nutrients you can get from food? The major types of nutrients are carbohydrates, lipids and proteins. 2. How are these nutrients used by your body? Carbohydrates are used for energy, proteins are used to build and repair tissue. Lipids are used for storage of energy when the energy is not needed. Gizmo Warm-up Have you ever wondered what is in your food? Scientists use a variety of tests to determine the nutritional content of food. You will learn four of those tests with the Identifying Nutrients Gizmo. 1. Below the Food samples label, drag tube A into the Food sample holder. Below the Benedict test, click the Test button. What is done in the Benedict test? The benedict test starts by dropping two drops of benedict into the test tube labeled A. The solution changes color based on the mixture of the solution and benedict. 2. The Benedict test is a test for monosaccharides; simple sugars like glucose or fructose (fruit sugar). In contact with monosaccharides, the Benedict solution turns from blue to green to orange. Does Sample A contain monosaccharides? Yes. Note: Disaccharides such as sucrose (table sugar) and lactose (milk sugar) are more complex than monosaccharides. The Benedict test does not detect disaccharides directly.

Introduction: Most food is composed of three types of molecules: carbohydrates, proteins, and lipids. ● Carbohydrates such as starches and sugars are a major source of energy. Simple sugars are found in sweets and fruits. Starches are found in potatoes, cereal, pasta, flour, and other plant products. ● Proteins are used in body structures such as muscles [Show More]
