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

(2) Elements
• Carbon (C)
• Hydrogen (H)
• Oxygen (O)

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

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

![Page 7: Name Date Hour Notes: Unit 1--Carbohydrates. (1) What is a carbohydrate? Type of Biomolecule Means: “hydrated carbon” –Has the same ratio of H and O as](https://reader036.vdocuments.us/reader036/viewer/2022062519/5697bfec1a28abf838cb8860/html5/thumbnails/7.jpg)
(5) Types of Carbohydrates• Monosaccharide = 1 Sugar
– Simple Sugar or Carb– Examples: Glucose, Fructose
• Disaccharide = 2 Sugars– Simple Sugar or Carb– Examples: Sucrose, Maltose
• Polysaccharide = Many Sugars– Complex Sugar or Carb– Examples: Starch, Cellulose

(6) Function
• Major:– Immediate energy– Intermediate energy
• Minor:– Structure

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

(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
