1) This macronutrient is used to build and repair body tissues.
Warm-Up 2/20/14 For each of the following, identify if it is describing a carbohydrate, fat, or protein. 1) This macronutrient is used to build and repair body tissues. 2) Its major role is to provide energy to every cell in the body. 3) These protect the cells and internal organs and allow us to store calories for times when food is scarce.
2
-Understand the different molecular structures of macromolecules.
Objective -Understand the different molecular structures of macromolecules. Agenda Review warm-up Macromolecule structure Classifying substances by their molecular structure.

4
Carbohydrates - Sugars
Made up of carbon (carbo-), hydrogen, and oxygen (-hydrate) Monosaccharides – simplest sugars Polysaccharides – made from monosaccharides
5
Carbohydrates - Starches
Made up of carbon (carbo-), hydrogen, and oxygen (-hydrate) Consists of lots of glucose molecules joined together Produced by most green plants as an energy storage Amylose Amylopectin
6
Consists of a sugar alcohol (glycerol) and three fatty acids
Fats - Triglycerides Ester Consists of a sugar alcohol (glycerol) and three fatty acids There can be saturated and non-saturated fats
7
Chain of amino acids covalently linked
Proteins Chain of amino acids covalently linked Amine group (-NH2) Carboxylic acid (-COOH)
8
Amino acids bond together by peptide bonds
Proteins Amino acids bond together by peptide bonds Peptide bonds are seen between the carbon atom and the nitrogen atom
