Understanding Carbohydrates: Structure and Function

Introduction to Carbohydrates

• Carbohydrates are biomolecules essential for life, primarily serving as an immediate energy source.

• Common sources of carbohydrates include sugars, bread, flours, and pasta.

Energy Storage and Weight Management

• Excess carbohydrate consumption leads to storage as lipids; managing carbohydrate intake is crucial for weight loss.

• Monosaccharides are the basic units of carbohydrates, typically found in cyclic forms that vary by carbon count.

Classification of Carbohydrates

• Carbohydrates can be classified based on the number of monosaccharides:

• Simple Carbohydrates: Include monosaccharides (e.g., glucose).

• Disaccharides: Formed from two monosaccharides (e.g., lactose).

Absorption and Complexity

• Simple carbohydrates are easily absorbed by the body, while complex carbohydrates (polysaccharides like starch) require more effort to digest.

Functional Groups in Carbohydrates

• The general formula for carbohydrates indicates two functional groups: aldehyde and ketone.

• Aldose classification applies if an aldehyde group is present; ketose applies if a ketone group is present.

Naming Monosaccharides by Carbon Count

• Monosaccharide names derive from their carbon count using Greek prefixes combined with the suffix "-ose":

• Example: A sugar with three carbons is called a "triose."
