Notes: Unit 1--Carbohydrates

2. (1) What is a carbohydrate?
Type of Biomolecule
Means: “hydrated carbon”
Has the same ratio of H and O as in Water

3. (2) Elements
Carbon (C)
Hydrogen (H)
Oxygen (O)

4. (3) Monomer
Monomer: Basic unit or Smallest unit of a polymer (larger molecule).
Carbohydrate Monomer:
Monosaccharide = Single Sugar

5. (4) Polymer
Polymer: A larger structure (molecule) made of many smaller units (monomers).
Carbohydrate Polymer:
Polysaccharide = Many sugars

7. (5) Types of Carbohydrates
Monosaccharide = 1 Sugar
Simple Sugar or Carb
Examples: Glucose, Fructose
Disaccharide = 2 Sugars
Examples: Sucrose, Maltose
Polysaccharide = Many Sugars
Complex Sugar or Carb
Examples: Starch, Cellulose

8. (6) Function Major: Minor: Immediate energy Intermediate energy
Structure

9. (7) Examples Table Sugar Bread Pastries
Plants (cell walls / outer covering)
Potatoes
Whole Grains

10. (8) Simple vs. Complex Carbs
RECALL:
Energy is stored in bonds
More Bonds = More Energy
Simple Carb:
Small molecule, Few molecules
Few bonds  Little Energy
Few bonds  Break Fast
Complex Carb:
Large molecule, Many parts
Many bonds  Lots of Energy
Many bonds  Break Slowly
