Lab Report 2 Introduction: The purpose of this laboratory exercise is to acquaint the investigator with common methods used to identify carbohydrates and proteins in the laboratory. Materials: 7 clean test tubes plus test tube rack dropper bottles of 1% starch‚ 1% protein‚ 1% glucose‚ and distilled water (DW)‚ slurries of honey‚ egg white‚ and saltine crackers dropper of IKI solution (starch test) dropper bottle of Benedict’s reagent (glucose test) dropper bottles of 10% NaOH and

Hypothesis: If synthetic saliva breaks down the cracker the most Then more of the cracker should be digested Because synthetic saliva contains amylase‚ and amylase helps break down complex carbohydrates. Interpretation: Data Table: The results of the iodine and Benedict’s tests for the Carbohydrate lab Test Tube contents and number Color of iodine test Color of Benedict’s test How much is present? 0= none 1= present How much glucose is present? 0= none 1= some 2= a lot #1 Starch (Control

Gatorade fits the bill perfectly for it fulfills a need; at the same time‚ it also satisfies the want for something that isn’t dull. 2. What do we want them to think‚ feel or do as the result of advertising? We want to make the potential buyers feel somewhat energized and ready to exercise on a whole new level once they have tested the new and improved Gatorade packed with carbohydrate that helps promote rapid fluid absorption

it to grow strong and maintain life. Carbohydrates (CHO) Carbohydrates are made of carbon‚ hydrogen‚ and oxygen. Carbohydrates are macro-nutrient that provides energy for the body; the energy gives our cell which helps our oxygen and nutrients to function when we sleep. 1. Different Types There are two types of carbohydrates‚ the simple and complex carbohydrates. Simple carbohydrates These are made up of a single basic sugar. Simple carbohydrates provide the sweet taste in our food. Fruit

Shake? The first thing that needs to be said about the meal replacement shake is that it’s not another word for a protein shake. These are two entirely different products. A meal replacement shakes contains a healthy balance of protein‚ fats‚ carbohydrates‚ vitamins and minerals. They are designed to give you all of the nutrients that you would get from a meal with less calories; which is why they are called “meal replacement shakes”. A protein shake‚ however‚

Lumbriculus variegates‚ or blackworm‚ is commonly found in stagnant water along the edges of marshes and ponds. Blackworms have a closed circulatory system‚ which in the blackworm includes a large dorsal blood vessel [1]. Glucose is the most common carbohydrate and is classified as a monosaccharide and is a reducing sugar. Glucose is called blood sugar as well because it circulates in the blood. When blood glucose is high‚ the pancreas releases insulin‚ which then helps to transport glucose into muscle
