Study Notes
Definition of Carbohydrates
- Organic compounds found in foods and living tissues, including sugars, starch, and cellulose.
- Composed of carbon, hydrogen, and oxygen in a 2:1 ratio, similar to water.
- Play a vital role in energy release within the human body.
Sources of Carbohydrates
- Common foods rich in carbohydrates include fruits, vegetables, and breads.
Composition of Carbohydrates
- Formed from three elements: carbon, hydrogen, and oxygen.
- Monosaccharides (single sugars) and disaccharides (two chemically linked sugars) are the basic structures, often referred to as sugars.
Importance of Carbohydrates for Living Things
- Serve as the primary energy source for living organisms.
- Provide structural functions in plants and some animals.
Monosaccharides
- Single sugar units, the simplest form of carbohydrates.
- Examples include glucose, galactose (found in milk), and fructose (found in many fruits).
Disaccharides
- Composed of two monosaccharides linked together.
- Common types include lactose (found in milk), maltose (found in malted foods), and sucrose (table sugar).
Structural Role in Plants
- Carbohydrates contribute to structural integrity and functions in plants and some animals.
Glycogen
- A polysaccharide stored in muscles that serves as an energy reserve for muscle contraction and movement.
