January 1999 B io Factsheet Example glucose fructose galactose Number 39 Carbohydrates: Revision Summary Carbohydrates contain 3 elements: Carbon (C)‚ Hydrogen (H) and Oxygen (O). Thus‚ if we remove water from carbohydrates‚ all that remains is carbon. Carbohydrates can be divided into 3 categories; monosaccharides‚ disaccharides and polysaccharides (Table 1). Table 1. Structure of monosaccharides‚ disaccharides and polysaccharides Category Monosaccharide (made of 1 sugar molecule)

Effects of Refined Sugar Refined sugar is made from sucrose extracted from raw sugar cane or sugar beets. Often added to processed foods and beverages‚ refined sugar has several forms such as granulated white sugar‚ brown sugar‚ fructose‚ sucrose‚ dextrose‚ high fructose corn syrup and malt syrup. The average American consumes about 22 tsp. of refined sugars each day according to the American Heart Association (Marina). Refined sugars have led to an obesity epidemic in America over the past 30 years

chains of sugars called glucans. These glucans glue the bacteria to the surfaces of the teeth and form a biofilm which is difficult to remove2. Glucansucrase has two reactions2. Firstly‚ the enzyme breaks sucrose into glucose and fructose. The fructose will be released‚ and the glucose will go to glucan chain. Glucansucrases are large proteins with many domains. These reactions are performed in the central portion of the enzyme‚ which is included in this structure. The enzyme also includes

transport systems such as glucose reabsorption in the kidney‚ or muscle contraction. There are two other monosaccharides: fructose and lactose. Fructose is found in sperm and in fruits‚ to make them more attractive to animals. Lactose is found in the milk of mammals and is an important energy supply for their young. These monosaccharides also help to build disaccharides. Glucose and fructose join together to form sucrose and glucose and lactose join to form galactose. Sucrose is the major transport carbohydrate

(agave syrup) is an alternative for sugar when people bega to know the harmful effects of it. But agave is much worse. One of the main problems with sugar is that it has excessive amounts of fructose. which can cause severe metabolic problems when consumed in. Whereas sugar is about 50% fructose and High Fructose Corn Syrup about 55%‚ Agave contains even more up to 70-90% Margarine is an replacement for butter due to the high saturated fat content‚ but what they didn’t know was that margarine had a

group is attached above the ring and on the first carbon. Fructose- a sugar of the hexose class‚ and is a simple ketonic monosaccharide found in many plants‚ where it is often bonded to glucose to form the disaccharide sucrose. Sucrose- Sucrose is a sugar‚ the organic compound commonly known as table sugar‚ cane sugar‚ beet sugar or‚ usually‚ just sugar. Galactose- is a monosaccharide sugar that is less sweet than glucose and fructose. It is a C-4 epimer of glucose. Galactan is a polymer of the
