The structural features of carbohydrates account for the fact that a wide variety of polysaccharides exist is pentoses and hexoses. The examples of pentose are ribose‚ deoxyribose‚ ribulose and xylulose. The examples of hexose are glucose which is found in fruits‚ fructose which is found in milk and galactose which is found in honey. Both pentoses and hexoses are mostly found in monosaccharides. They are the most simplest sugar which cannot be futher hydrolysed into smaller units. They contain

metabolized in the body! Digestion is the chemical breakdown of food molecules into smaller molecules that can be used by various cells within the body. The breakdown is initiated when food is ingested in the mouth and specific enzymes are exposed to components within the food molecules. Digestion begins in the mouth with mastication‚ or chewing‚ performed by the teeth. The purpose of chewing is to grant the food more exposure to enzymes‚ therefore allowing chemical digestion to occur faster. The presence

variable The variable is the important aspects of the research. In research the concept are measure from variable. Variable are anythings that can take on differing or varing values. it mean that the value of variable vary from person to person‚ time to time or place to place but the meaning of variable are same to all. Thus variable are the charactestics of person‚ groups‚ objects‚ ideas‚ feeling or other thing that researcher want to measure. Variables are thus anything that can take on differing

more or less linear way. To say it differently‚ price differences between hotels underscore the presence or not of some variables expected to influence the latter. It is essential for hotels to understand how they can price their rooms and maximize yield while remaining competitive. Therefore‚ we conducted an extensive analysis to help hotel revenue managers find out what key variables influence price on Orbitz. The data were gathered from Orbitz.com directly. The data is about 1623 hotels that are located

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

What are Carbohydrates? Carbohydrates are the sugars‚ starches‚ and fibers found in fruits‚ grains‚ vegetables and milk products. Carbohydrates are sugars that break down inside the body to create glucose. Glucose is moved around the body in the blood and is the primary source of energy for the brain‚ muscles‚ and other essential cells. There are two types of carbohydrates‚ simple and complex; Simple carbohydrates refer to sugars with a simple molecular construction of one or two parts. Because
