Carbohydrates and Monosaccharies
Carbon atoms very readily form bonds with other carbon atoms which allows a sequence of carbon atoms to be built up.
Many organic molecules are made up of long chains of individual molecules. Each individual molecule is called a monomer, these longer chains of repeating units are called polymers.
- Carbohydrates monomer is a sugar or a saccharide.
- A single monomer is called a monosaccharide.
- A pair of monosaccharides is called a disaccharide.
- Monosaccharides in large numbers are polysaccharides.
Monosaccharides are sweet tasting and soluble. (CH2O)n
Disaccharides and Polysaccharides
Disaccharides:
- Glucose + glucose > maltose.
- Glucose + fructose > sucrose.
- Glucose + galactose > lactose.
When this happens a molecule of water is removed - this is a condensation reaction. A glycosidic bond is formed.
When water is added to a…
