In this lab, various solutions will be tested for different forms of macromolecules, such as proteins, lipids and carbohydrates. The solutions being tested include control tests (both positive and negative), textbook suggested substances, as well as four other substances which will be tested and analysed for macromolecules. The first test is a test for proteins and peptides. Protein is one of the main categories of macromolecules, protein is essential for system function, maintaining structure and enzyme production. It maintains muscles, bones, blood and essential organs. Peptides are compounds composed of two or more amino acids linked in a chain, and are essential to diet. Long chains of peptides are proteins but shorter chains are just as important. They …show more content…
Carbohydrates have three types of subunits, monosaccharides, disaccharides and polysaccharides. Monosaccharides are simple sugars, made of a single sugar molecule, disaccharides are the result of two monosaccharides bonding together and polysaccharides are a complex carb consisting of many linked simple sugars. Carbohydrates are used by the body in the configuration of glucose which is converted to glycogen and stored in the liver and muscles until it is needed for energy. The different forms of carbohydrates are found in many foods. Examples of monosaccharides are glucose, fructose and galactose which can be found in fruits, veggies and some dairy products. Table sugar is a disaccharide formed of glucose and fructose which occurs naturally in fruits and artificially in many processed foods. Lactose is another disaccharide, composed of glucose and galactose which is the main sugar in milk. Starch, glycogen and cellulose are all examples of polysaccharides. The final test is a test for the presence of fats. Fats are a form of the macromolecule class of lipids. Lipids are important for long term
