Carbohydrates are broken down into simple sugars that are used by the body for energy. As carbohydrates are eaten, the digestive tract breaks them down into monosaccharide units, or glucose. The glucose enters the bloodstream and travels first to the brain, which runs entirely on energy from glucose.
After the glucose needs of the brain have been met, the remaining glucose travels to the other tissues of the body. Once all of the immediate glucose needs of the body have been met, the remaining glucose converts to glycogen, a polysaccharide storage form of glucose. Glycogen is mainly found in the liver and muscles of the human body. If there is more glycogen available than room to store it, the body converts the excess to fat. The fats are stored in the adipose tissue. Once glucose is changed into glycogen and then fat it cannot be changed back into glucose, but it can still be used for fuel. Parts of the body that can only run on glucose for energy, such as the brain, cannot use fats for fuel. Carbohydrates exist in almost every type of food that humans ingest. Simple carbohydrates are found in foods like white bread, pasta and fruit. Complex carbohydrates are found in items such as whole grains.Learn More
Yeast primarily survives by eating simple sugars like glucose and fructose. There are many types of yeast, some of which can eat different sugars, including disaccharides, which are slightly more complex than simple sugars.Full Answer >
Carbohydrate monomers are called monosaccharides, which are also known as simple sugars. They are composed of either five or six carbons that have a ring-like structure and form a single sugar. Examples of monomers are glucose, fructose and galactose, which are all simple sugars. There are also disaccharides, which are two simple sugars bonded together, but they are not the main monomers of carbohydrates.Full Answer >
Carbohydrates are separated into three subunits: monosaccharides, polysaccharides and oligosaccharides. Monosaccharides are the smallest of the subunits and are made up of single sugar molecules. The most common monosaccharides are the sugars fructose and glucose, and these typically take on a ring-shaped structure.Full Answer >
Plants create carbohydrates during photosynthesis, and while the initial product of photosynthesis is glucose, plants store carbohydrates as one of several saccharides. The human body stores carbohydrates that it does not use quickly. While it stores some of this energy in the liver and muscles in the form of glycogen, it stores the rest as fat. According to About.com, the body is able to live without dietary carbohydrates if needed.Full Answer >
