Carbohydrates are orgainc
compounds containing carbon, hydrogen and oxygen.
They are primarily utilised as an energy source
though they have other important functions.
|
- Carbohydrates include simple
sugars such as monosaccharides (e.g. glucose,
galactose and fructose). Two monosaccharides can
bejoined together to form a disaccharide e.g.
sucrose (common sugar) composed of glucose and
fructose.
|
|
- When a number of monosaccharides
are covalently joined together, the resulting
molecule is called a polysaccharide. Starch is a
common polysaccharide found in plants while Glycogen
is a polysaccharide found in animals (liver and
muscle)
