Carbohydrates are the main energy source in your everyday activity. It is the biochemical name for sugar containing molecules including single sugar like glucose. Carbohydrates are the sugars and starches found in breads, cereals, fruits, vegetables.
During digestion the sugars and starches are changed into a simple sugar called glucose and locked into the molecular bonds of basic fuel molecules like glucose, fructose, fatty acids, and amino acids. The glucose is stored in the liver until cells need it for energy. The energy from the food allows us to move, to do work by muscle contraction, and to keep your body warm.
Carbohydrates are used to provide energy especially for athletes when they are in a time of need. For example, when a runner is about to run a marathon they drink and eat high carbohydrate products. The high carbohydrate bars supply about 200 to 260 calories. The best carb on the market are the Power Bars Performance which contain 45 carbs. The second best carbohydrate bar is the Clif Bar which has 41 carbs. Also, the best carbohydrate drink on the market is HOOAH! These are the biotechnology applications that deal with carbohydrates.
