Slide 4

Remember Organic means contains carbon

Slide 5

Simple Sugars Starches

Slide 6

Slide 7

Fats and oils Make cell membranes

Slide 8

Phospholipid

Slide 9

Polymers of amino acids

Slide 10

Proteins function in just about everything Structure- skin, hair, muscle Signaling hormones Transport Enzymes

Slide 11

Proteins are polymers of amino acid monomers There are twenty different amino acids. Amino acids differ in R groups

Slide 12

Proteins differ in the number and order of amino acids Amino acids interact to give a protein shape Incorrect amino acids change a proteins structure and function.

Slide 13

Nucleic acids are monomers of nucleotides Contain C, H, O, N, P Store and transmit genetic information (DNA and RNA)

Slide 14

Phosphate group Sugar Nitrogen base

Slide 16

Describe at least one function of each group of organic compound. Why are proteins considered polymers but lipids are not? What class of macromolecule does the following compound belong to?

Slide 17

Make a study guide for yourself. List each of the four organic compounds with Their monomer and polymer (structure) At least two functions How would you test for this organic compound in the lab?

Slide 18

Chemical Reactions change substances by breaking and forming chemical bonds Reactants are changed (what you react) Products are made (what you produce)

Slide 19

Activation Energy is the amount of energy that needs to be absorbed to start a chemical reaction (to activate the reaction)

Slide 20

Release more energy than they absorb (Release heat)

Slide 21

Absorb more energy than they release (take in heat energy feels cold)
