Carbohydrate

Intro: Carbohydrate, any of a large group of compounds in which hydrogen and oxygen, in the proportions in which they exist in water, are combined with carbon; the formula of most of these compounds may be expressed as Cn(H2O)n. Structurally, however, these compounds are not hydrates of carbon, as the formula would seem to indicate. Carbohydrates, as a class, are the most abundant organic compounds found in nature. They are produced by green plants and by bacteria using the process known as photosynthesis...

complex carbohydrates

Complex Carbohydrates PERSONAL SUMARY: There is a very real difference between simple and complex carbohydrates. Let's look at them. Simple carbohydrates, found in rice, pasta, white potatoes, and some dairy products, contain sugars that are broken down quickly by your body. This will provide your body with a quick burst of energy, but if the carbohydrates are not used quickly, the sugar will turn to fat. That's why low-carb diets cut them out. But those diets often lump all carbs together ...

Carbohydrates Essay

Carbon, Hydrogen and Oxygen. These three simple elements make up one of the most useful substances for many living organisms: Carbohydrates. Carbohydrates are used for numerous processes in organisms from acting in important roles of cellular recognition in the human body to storing chemical energy in plants in the form or starch. The roles of carbohydrates in the human body alone are numerous; providing energy for working muscles, providing energy for the regulation of blood glucose, preventing...

Analysis of Carbohydrates

 Abstract Carbohydrates are the most abundant organic compounds in the plant world. They act as storehouses of chemical energy (glucose, starch, glycogen); are components of supportive structures in plants (cellulose),crustacean shells (chitin), and connective tissues in animals (glucosaminoglycans); and are essential components of nucleic acids (D-ribose and 2-deoxy-D-ribose). Monosaccharides, oligosaccharides, and polysaccharides are theclassifications of carbohydrates. This experiment involves...

DIGESTION SYSTEM OF CARBOHYDRATE Carbohydrate Digestion and Absorption Basically, digestion of carbohydrate involves conversion of the large molecules of carbohydrates like di-saccharides and polysaccharides into simple mono-saccharide molecules which can be easily absorbed by the body. The first step of digestion is the moment we put the food in mouth. As we chew the food, the saliva released by the salivary glands of the mouth starts its work of breaking up of the carbohydrates. This is possible...
