Study Notes
Classification of Carbohydrates
-
Simple Carbohydrates (Sugars)
- Monosaccharides (e.g. glucose, fructose, galactose)
- Disaccharides (e.g. sucrose, lactose, maltose)
-
Complex Carbohydrates (Polysaccharides)
- Oligosaccharides (e.g. raffinose, stachyose)
- Polysaccharides (e.g. starch, glycogen, cellulose)
Functions of Carbohydrates
- Energy Source: primary source of energy for the body
- Structural Role: found in cell walls and exoskeletons of organisms
- Storage: stored in the form of glycogen in the liver and muscles
Types of Carbohydrates
- Starch: complex carbohydrate found in plants, broken down into glucose
- Glycogen: complex carbohydrate found in animals, broken down into glucose
- Fiber: complex carbohydrate found in plants, not digestible by humans
- Cellulose: complex carbohydrate found in plant cell walls, not digestible by humans
Digestion and Absorption of Carbohydrates
- Mouth: carbohydrates broken down into simple sugars by salivary amylase
- Small Intestine: carbohydrates broken down into simple sugars by pancreatic amylase
- Absorption: simple sugars absorbed into the bloodstream and transported to the liver
Importance of Carbohydrates
- Brain Function: primary source of energy for the brain
- Athletic Performance: important source of energy for muscles during exercise
- Overall Health: play a crucial role in maintaining overall health and well-being
