Structure and Function of Complex Carbohydrates Complex carbohydrates are very common in animals, plants, and bacteria. They are constituents of cell membranes, as well as subcellular materials of cells.
Scientists and dietitians used to group carbohydrates into two types: complex carbohydrates and simple carbohydrates. Complex carbohydrates include starches and fiber. Simple carbohydrates include sugar that occurs naturally in fruits, vegetables and milk as well as brown sugar, white sugar, honey and any sugar added to foods during processing. The physical, chemical, and biological properties of carbohydrates depend on their primary structures and, less frequently, on their higher-order structures. While monosaccharides are comprised of a single saccharide unit, oligosaccharides are less clearly defined and may consist of from 2-10 glycosidically linked monosaccharide units.
Therefore, the typical formula for a carbohydrate is #CH_2O#. --> Carbon with 2 Hydrogen and 1 Oxygen: #C + H_2O#. The most common sugar is glucose from the photosynthesis reaction. Glucose has a formula of #C_6H_12O_6#. Sucrose which is table sugar is #C_(12)H_(22)O_(11)#. For example, deoxyribose, a component of DNA, is a modified version of ribose; chitin is composed of repeating units of N-acetyl glucosamine, a nitrogen-containing form of glucose. Division. Carbohydrates are polyhydroxy aldehydes, ketones, alcohols, acids, their simple derivatives and their polymers having linkages of the acetal type. Carbohydrates are an essential part of a healthy diet, yet it’s important to know that not all of them are created equal. So how do you tell the difference between “good carbs” and “bad ... What are Refined Carbohydrates or Refined Carbs ? The healthiest sources of carbohydrates—unprocessed or minimally processed whole grains, vegetables, fruits and beans—promote good health by delivering vitamins, minerals, fiber, and a host of important phytonutrients. This list of carbohydrate foods will prove that all carbohydrates are not created equal. And it's vitally important to your health that you know the good carb bad carb difference. The good carbs on the list of carbohydrate foods can provide your body with energy, optimum nutrition, proper brain and organ function and a healthy, attractive ...
Some are classified as simple carbohydrates or simple sugars because they have a simple chemical structure, which makes them easy to digest and absorb. Sources of simple carbohydrates include ... the sum total of all of the chemical reactions that occur in an organism Energy released from these macromolecules, and matter supplied by them, is used to maintain the body's metabolism
