Unformatted text preview: What do we gain after eating these foods? The answer is simply because of CARBOHYDRATE! CARBOHYDRATE What is Carbohydrate? Carbohydrate is an organic compound whose General formula is C m (H 2 O) n , that is, consisting only of carbon, hydrogen and oxygen, the last two in the 2:1 atom ratio. Alternate name is saccharide (Greek) Carbohydrates can be viewed as hydrates of carbon. The names of carbohydrates very often end in the suffix -ose. Fill numerous roles in living things- storage and transport of energy (e.g., starch, glycogen)- Structural components (e.g., cellulose in plants and chitin in arthropods). How are Organisms related with Carbohydrate? Animals (including humans) break down carbohydrates during the process of metabolism to release energy. For example, the chemical metabolism of the sugar glucose is shown below: C 6 H 12 O 6 + 6 O 2 6 CO 2 + 6 H 2 O + energy Animals obtain carbohydrates by eating foods that contain them, for example potatoes, rice, breads, and so on. These carbohydrates are manufactured by plants during the process of photosynthesis. Plants harvest energy from sunlight to run the reaction just described in reverse: 6 CO 2 + 6 H 2 O + energy (from sunlight) C 6 H 12 O 6 + 6 O 2 A potato, for example, is primarily a chemical storage system containing glucose molecules manufactured during photosynthesis. In a potato, however, those glucose molecules are bound together in a long chain. As it turns out, there are two types of carbohydrates, the simple sugars and those carbohydrates that are made of long chains of sugars - the complex carbohydrates. Types of Carbohydrate When considering the structure of starch and cellulose, exactly tiny identical units are found to be connected as long chains. However, the subunits and branches of each bond are different. The structure of carbohydrate is divided into three types....
