Research a specific carbohydrate and its importance in biology. Discuss its structure, whether it is a monosaccharide, disaccharide, or polysachardide. If it is a monosaccharide, discuss its various isomers, including where they are found and their approximate composition (i.e., percentages). If it is a disaccharide or polysaccharide, discuss its important linkages as well as where it is found in nature.
Also describe which carbohydrate test could be used to detect its presence in solution.
Your initial post must meet a minimum writing requirement (one paragraph with at least five sentences). Respond to at least two posts (one paragraph with at least three sentences each). Your responses must contribute meaningfully to the discussion. Posts consisting of “Thank you”, “You’re welcome”, “I agree”, or “Me too” do not contribute meaningfully to the discussion. Critique other students’ postings in a positive

1. (Jypsy)The specific carbohydrate I’m going to discuss is starch. Starch is a polysaccharide , containing branched chains of glucose with a straight that can be broken down to produce energy. It is composed of two constituents : amylose , a straight-chain polymer of 20-300 glucose units, and amylopectin, a larger branched polymer group. The a-d-glucose molecules in both amylose and amylopectin are bonded by 1,4-a-glycosidic linkages. Starch is stored in plants and seeds ; examples of starchy food include: potatoes, bread, beans and pasta. It is the major source of carbohydrate in the human diet, and it is used as an energy source.
An iodine test is used for the detection of starch in a solution.
2. (Markissa)For humans, starch is the most essential source of energy. The body digests starch by converting it to glucose, which is then absorbed into the circulation and circulated throughout the body. Glucose is the primary source of energy for nearly every cell, tissue, and organ in the body. When there is too much glucose in the blood, the liver stores it as glycogen. Starch is the most essential polysaccharide and storage polymer in plants, and it may be found in abundance in the leaves, stems, fruits, seeds, tubers, and roots of many different species. Amylose and amylopectin are two forms of polymer chains found in starch. Protein has a branching structure with glycosidic links, whereas amylose has a linear structure with glycosidic linkages. Polysaccharides are made up of cyclic monomers (monosaccharides) that are usually linked together by glycosidic bonds. Polysaccharides are present in the exoskeletons of arthropods. Polysaccharides can be found in arthropod exoskeletons and certain fungus cell walls. Surgical threads are one of its many applications. The presence of starch in a sample may be determined using an iodine test. Starch may be distinguished from monosaccharides, disaccharides, and other polysaccharides using the iodine test. It also differentiates between starch, glycogen, and carbs.
