Study Notes
Carbohydrate Classification
- Monosaccharides: Simple sugars (glucose, fructose, galactose). Glucose is the primary energy source.
- Disaccharides: Two monosaccharides linked together (lactose, sucrose).
- Oligosaccharides: 3-10 monosaccharides linked; difficult to digest, causing GI upset and flatulence. They have a prebiotic effect.
- Polysaccharides: Thousands of monosaccharides (cellulose, starch). Found in cereal grains (corn, wheat, barley, rice), and potatoes.
Carbohydrate Functions
- Energy Source: Carbohydrates are converted to glucose in the small intestine for energy for most body cells, including the brain and nervous system.
- Glucose Storage: Excess glucose is stored as glycogen in the body for later use. Glycogen can turn into fat, contributing to obesity.
- Complex Carbohydrate Breakdown: Complex carbs require breakdown by the body before absorption.
- Glycogen Mobilization: Stored glycogen is released as needed.
- Energy Conversion: Converted into glucose that supplies body heat.
- Blood Glucose Regulation: Important for managing diabetes.
- Lactose Production: Required for lactation.
- Growth, Gestation, and Lactation: Crucial for supplying extra energy needs.
Carbohydrate Types
- Digestible Carbohydrates: Primarily monosaccharides and disaccharides.
- Indigestible Carbohydrates: Polysaccharides. Some (like starch) can be improved by cooking. Others, like cellulose, are dietary fiber.
Fiber Function
- Digestion Regulation: Resists small intestine enzymes and ferments in the large intestine, aiding in regulating gut bacteria.
- Dietary Effects: Not a required nutrient, but aids in digestion, keeps animals full longer, and helps control blood glucose levels (like in diabetes).
Carbohydrates in Pets (Cats)
- Cat Metabolism: Cats have unique metabolism, limiting their ability to utilize large amounts of carbs.
- Diet Recommendations: A diet exceeding 40% dry matter carbs can cause diarrhea, bloating, and flatulence. Low-carb, high-protein diets maintain normal blood glucose.
Carbohydrate Sources (Pet Food)
- Common Source: Cereal grains are the most common.
- Digestibility: Grains need to be ground or cooked appropriately to enhance absorption.
- Kibble Texture: Carbohydrates create the texture of kibble for shelf stability and palatability. They aid in tartar control.
- Examples: Oats, whole corn, barley, brown rice, potatoes, and millet are common sources in pet food.
