Study Notes
Carbohydrates Overview
- Carbohydrates lacking fiber, vitamins, and minerals are termed refined carbohydrates.
- They are often stripped of nutrients during processing, leading to less health benefits.
Photosynthesis
- The process by which plants convert solar energy into chemical energy is known as photosynthesis.
- It involves the transformation of carbon dioxide and water into glucose and oxygen, using light energy.
Carbohydrate Monomers
- An example of a carbohydrate monomer is glucose, which is a simple sugar or monosaccharide.
- Monosaccharides serve as the building blocks for larger carbohydrate molecules.
Carbon Atoms in Trioses
- Trioses contain three carbon atoms in their structure.
- They are a type of monosaccharide and play a role in metabolic processes.
Complex Carbohydrates
- Carbohydrates containing two or more sugar molecules are classified as complex carbohydrates or polysaccharides.
- They are commonly found in starchy foods like grains, legumes, and vegetables.
Structural Carbohydrates
- Cellulose is a structural carbohydrate and is the main component of the plant cell wall.
- It provides rigidity and strength to plant structures.
Importance of Carbohydrates
- Carbohydrates are essential nutrients that provide a primary source of energy for the body.
- They are crucial for maintaining proper metabolic functions and overall health.
Glucose Utilization
- Glucose is utilized by the body as a vital energy source for cells, tissues, and organs.
- It is crucial for brain function and physical activity, converting into energy via cellular respiration.
Etymology of 'Carbohydrate'
- The term 'carbohydrate' originates from the combination of carbon (carbo-) and water (-hydrate), highlighting its basic chemical structure.
Chemical Classification of Carbohydrates
- Carbohydrates are classified based on their chemical structure into simple (monosaccharides and disaccharides) and complex carbohydrates (oligosaccharides and polysaccharides).
Sources of Simple Carbohydrates
- Simple carbohydrates are abundantly found in fruits, milk, honey, and refined sugars.
- Their quick absorption makes them a rapid source of energy but can lead to spikes in blood sugar levels.
