proteins‚ but are good sources of protein)‚ eggs‚ grains and beans. Carbohydrates - Complex carbohydrates are chains of simple sugars. Their primary role in animals is to provide energy. Plants use starch as an energy storage molecule‚ and use complex carbohydrates such as cellulose for support. Examples of carbohydrates are sucrose‚ glucose‚ fructose‚ starch‚ cellulose‚ and glycogen. A good dietary source for carbohydrates would be bread and grains. Fats - Fats are a complex of fatty acid

Introduction In this experiment‚ glucose‚ maltose‚ lactose and sucrose are used for testing reducing and non-reducing sugars. Glucose is monosaccharide while maltose‚ lactose and sucrose are disaccharides of carbohydrates. Monosaccharaides are the monomers which make up all other carbohydrates and cannot be broken into smaller molecules by hydrolysis. Disaccharides are formed from the condensation reaction between two monosaccharaides and are linked by glycoside bond. All monosaccharaides and some

Sugar Addiction and Its Effects on the Human Body Roy Marvitz Course: BSC-1010 Gary Brannan Date: April 03‚ 2013 Sugar Addiction and Its Effects on the Human Body Research done recently has shed light on the issue of sugar addiction and its effects on the health of human beings. The qualities in sugar that make it addictive have been confirmed by scientists. A study by Colantuoni‚ Carlo‚ Pedro‚ Rada‚ McCarthy‚ Patten‚ Nicole‚ Chadeayne‚ and Hoebel in 2002 sought to establish whether

light-dependent stage‚ water is photolyzed by the light into Hydrogen and oxygen. Hydrogen enters the second stage and oxygen became a by-product. Then‚ in independent stage‚ and enzyme catalyse the reduction of carbon dioxide by hydrogen‚ forming a carbohydrate‚ which is glucose. Glucose can be translocated in the dorm of fructose or sucrose or stored as starch in granules. To put it simply‚ carbon dioxide and water molecules form glucose and oxygen with light energy‚ and the overall equation for photosynthesis

1.0 ABSTRACT The production of reducing sugars by acid of carbohydrate cereals powder‚ jams (total sugar content) and jams (reducing sugar content) were performed in order to study reducing sugar production. The study involved hydrolysis carbohydrate cereals powder and jams by immersing in boiling water at environmental temperature. Acid hydrolysis was carried out through reflux boiling for 20 minutes with 10ml 0f 1.5M concentrations of diluted sulphuric acid. Reducing sugars concentrations

CHAPTER 4 CARBOHYDRATES OVERVIEW This chapter discusses the energy-yielding nutrient‚ carbohydrates. Simple and complex carbohydrates are defined and identified with a highlight on fiber. Carbohydrates found in the food we eat‚ including various alternative sweeteners‚ are explored. The digestion and absorption of carbohydrates are examined. Carbohydrate intake recommendations are summarized and the roles of simple and complex carbohydrates in health maintenance are explored. The potential

Brief Background: Amylase is a digestive enzyme‚ produced mainly by the salivary glands and the pancreas‚ to break down starch in food into smaller carbohydrate molecules and disaccharides such as maltose. It can be found in humans and some other mammals. Some plants and bacteria may also produce amylase. After being broken down into smaller carbohydrate molecules‚ it can be converted into a monosaccharide such as glucose‚ which fuels processes for organism function. There are two variations of this

The presence of carbohydrates in a solution can be determined by a qualitative test of Molisch test. Molisch test is a general‚ sensitive chemical test and positive for all kinds of carbohydrates which in free form or in combined form. The test is based on the dehydration of the carbohydrate by concentrated sulfuric acid to produce an aldehyde which condenses with two molecules of phenol‚ resulting in a coloured compound. Molisch reagent is a solution of α-napthol in 95% ethanol. The aldehydes produced

Not only that‚ I feel full longer because it contains complex carbohydrates. Another way of maintaining a healthy lifestyle is physical activity (Student Health 101‚ 2013‚ Slide 3). “According to the American Heart Association‚ cardiovascular disease is the number one killer in America. Lack of physical activity is
