Carbohydrates
Carbohydrates are macromolecules made out of carbon, hydrogen and oxygen in 2 to 1 ratio. They are the fuel our body uses for energy, cell regeneration, cognitive processes and movement. Based on complexity, carbohydrates can be:
-
Simple carbohydrates
-
Complex carbohydrates
Simple Carbohydrates are divided into:
-
Monosaccharides
- Single unit sugars: glucose (cell fuel), ribose, galactose, xylose and fructose
- They are the simplest carbohydrate units that cannot be broken down to smaller units
- Blood sugar (glucose)
- Disaccharides
- Disaccharides are made from two joined monosaccharide units, such as glucose and fructose
- Can be broken down to monosaccharides by digestion
- Table sugar (sucrose, made from glucose and fructose), milk sugar (lactose, made from glucose and galactose)
While complex carbohydrates are divided into:
- Oligosaccharides
- Oligosaccharides are made from three to ten monosaccharide units
- Can be partially digested by body
- Artichokes, burdock, chicory, leeks, onions, and asparagus (fructo-oligosaccharides made from 3+ fructose units), soy and soybeans (Galacto-oligosaccharides, made from 3+ galactose units), beans and legumes
- Polysaccharides
- Polysaccharides are made from more than ten monosaccharide units
- Potato, rice, wheat, and corn (starch, made from glucose units), animals starch (glycogen, made from glucose residues)
- Starch and glycogen can be broken down to monosaccharides by digestion
- Cellulose that cannot be fully digested and is a good source of dietary fiber
Both simple and complex carbohydrates are an essential part of a healthy diet.
