One aspect of nutrition that is vital is protein. Protein is one of four major building materials in the human body. Proteins are composed of carbon with Hydrogen‚ Oxygen‚ and Nitrogen attached. Some proteins also have Sulfur‚ Phosphorus‚ and Iron. Proteins are made up of sub-units called amino acids‚ of which there are twenty. These are just the basics of what proteins are composed of. Amino acids‚ which are the sub-units of Proteins‚ can be divided into two groups. Eleven of the twenty amino

is a readily available source of energy. Fructose * Is chemically similar to glucose but it is found only in fruits & honey. GA lactose * Does not occur naturally in foods‚ but it forms as a result of the digestion of the disaccharide. Disaccharides Are formed through the combination of any 2 monosaccharides. * Glucose +fructosesucrose * Glucose+ GA lactose lactose * Glucose +Glucosemaltose Starch * It acts as a store of energy which can be converted back into

for our vital functions such as breathing and sleeping. There are two types of carbohydrates‚ simple and complicated. Monosaccharides‚ disaccharides and polysaccharides. L. O. 1.2 Carbohydrates are split into different classifications depending on how many molecules they have. Monosaccharide: one sugar molecule. E.g. Fructose‚ Galactose or Glucose. Disaccharide: Two sugar molecules linked together by a glycocidic bond. E.g. Glucose + Glucose = Maltose Glucose + Fructose = Sucrose Polysaccharide:

Title: Benedict ’s test for Reducing Sugars Testable Question: Are all carbohydrates reducing sugars? Hypothesis: If the carbohydrate contains available ketone or aldehyde molecules then they are reducing sugars. Variables: a. Independent: Function groups react w/ reagent b. Dependent: Color change (red‚ orange‚ yellow) Control: Water Materials: - 4 mL of each solution (Water‚ Starch‚ Glucose‚ Maltose‚ Sucrose‚ Onion Juice‚ Potato slice‚ Milk) - 8 test tubes

Monosaccharides can bond with others in a dehydration synthesis. This is a special reaction that consists of the removal of a water molecule to combine two or more monosaccharides (Volesky). Two bonded monosaccharides is a disaccharide. Only monosaccharides and disaccharides make up simple sugars such as glucose and lactose (American Diabetes Association). Polysaccharides‚ or many monosaccharides bonded‚ create more complex compounds like starches‚ cellulose‚ and chitin (McKinley Health

Introduction: According to chemists‚ hydrolysis is defined as the breaking of a compound involving a reaction with a water molecule. The goal of this experiment is to three-dimensionally show how disaccharides are transformed into monosaccharides using an acid-catalyzed hydrolysis reaction. For the purpose of this lab‚ it is quite useful to fully understand the following terms: optical rotation and carbohydrate. Optical rotation is measured by a polarimeter‚ which measures the polarization of light
