Study Notes
Carbohydrates
- Polysaccharides are carbohydrates composed of many sugar molecules.
- Grape sugar is another name for the monosaccharide glucose.
- Glucose plays a crucial role in the body as a primary source of energy for cells.
Monosaccharides
- Galactose is a monosaccharide found naturally in milk and dairy foods.
- Fructose is commonly found in fruits, honey, and some vegetables.
- When fructose is consumed, it is converted into glucose or stored as glycogen in the liver.
Glycogen and Glucose
- Glycogen is the most abundant biomolecule on Earth and is stored in the liver and muscles.
- Blood glucose plays a crucial role in regulating insulin hormone, which helps to lower blood glucose levels.
- The primary source of glucose in the body is the breakdown of glycogen stored in the liver.
Lactose and Galactose
- Galactose combines with glucose to form lactose, a disaccharide.
- Lactose is hydrolyzed by the lactase enzyme in the intestine.
- Lactose intolerance occurs when the body is unable to digest lactose due to a deficiency of lactase enzyme.
Fibers
- Dietary fibers are classified into soluble and insoluble fibers, which are indigestible polysaccharides found naturally in plants.
- Total fibers in the diet can be calculated by adding soluble and insoluble fibers.
- Functional fibers have beneficial physiological effects in the diet, including promoting regular bowel movements and supporting healthy blood sugar levels.
Glycogen Storage Diseases
- Pompe disease is a glycogen storage disease caused by a deficiency of the enzyme acid alpha-glucosidase, leading to an accumulation of glycogen in cells.
- Hurler syndrome is a genetic disorder caused by a deficiency of the enzyme alpha-L-iduronidase.
Enzymes and Reactions
- The enzyme glucose-6-phosphatase plays a crucial role in regulating blood glucose levels.
- Maltase is the enzyme responsible for breaking down maltose into glucose.
- Lactase is the enzyme responsible for hydrolyzing lactose in the intestine.
