Study Notes
- Carbohydrates are hydrates of aldehyde or ketone derivatives containing C, H, and O.
- They serve as a major energy source and storage form of energy.
- Carbohydrates are also components of cell membranes and structural components in plants, bacteria, and insects.
- Carbohydrates can be classified into monosaccharides, disaccharides, oligosaccharides, and polysaccharides.
- Glucose is the only carbohydrate directly used for energy or stored as glycogen.
- The brain is completely dependent on blood glucose for energy production.
- Glucose metabolism generates intermediate products such as pyruvic acid, lactic acid, and acetyl coenzyme A.
- The complete oxidation of glucose yields carbon dioxide, water, and ATP.
- Glycol aldehyde is the simplest carbohydrate.
- Glucose does not accumulate in the muscle and is quickly metabolized.
