Transcript of Monosaccharide, Disaccharide, Polysaccharide.

Monosaccharide, Disaccharide, Polysaccharides.
by David, Samitra, Edith, Xyu

They are units of carbohydrates and cannot be further hydrolise to simpler compounds.
Monosaccharide are the simpliest form of sugar and they are usually colorless and can dissolve in water.
Some monosaccharide taste sweet
Monosaccharide -simpliest unit of carbohydrates
They contain 3 to 7 carbons -
Examples of Monosaccharide: Glucose, Fructose, Galactose, Deoxyribose, Ribose

Monosaccharide Info
Disaccharide are two simple sugars joined by dehydration synthesis and Sucrose is broken down into glucose and fructose, excess glucose is stored as fat.

Disaccharides are formed when two monosaccharides are joined together and a molecule of water is removed, a process known as dehydration reaction. For example; milk sugar (lactose) is made from glucose and galactose whereas the sugar from sugar cane and sugar beets (sucrose) is made from glucose and fructose.
Polysaccharides are formed by three or more monosaccharides, for example Amylose (starch), Amylopectin, Glycogen (animal storage polymer), Cellulose, etc. AMYLOSE AND AMYLOPECTIN.
Foods that contain Monosaccharide:
Disaccharides are generally water-soluble and sweet when ingested.
Polysaccaride- carbohydrate molecules composed of long chains of monosaccharide units bound together by glycosidic .
polysaccharide is joined to monosaccharide. is also more than two unist.
can be found in rice, potato, corn and wheat.
Monosaccharides are the simpliest units of carbohydrates and the simplest form of sugar. Monosaccharides are the building blocks of disaccharides (Such as sucrose and lactose) and polysaccharides (such as cellulose and starch.)
Molasses has a high content of the monosccharide glucose. Cherries contain the monosaccharide fructose, and yogurt contains the monosccharide galactose.
Number of Carbon Atoms
Whats a "Monosccharide"?
a carbohydrate that does not hydrolyze, as glucose, fructose, or ribose, occurring naturally or obtained by the hydrolysis of glycosides or polysaccharides.
n = 3, that means that there are three carbon atoms and these monosaccharides are called trioses. If n = 4, there are four carbon atoms, so these monosaccharides are called tetroses and so on...
Haworth Projection
is a common way of representing the cyclic structure of monosaccharide.
