Textbook Reading p HW: Reading & Notetaking p.151 – 152 Reminder: Data Table, Graph & Procedure due 2/5 & 2/6 (15 Points) Reminder: Chap 6, 7 & 8 test on 1/22 & 1/23

Daily Reflection Prompt: Write 3 facts about polymers.

What is a Isomer? Compounds that have the same chemical formula but different structural formulas are called isomers Butanes and isobutane have different melting points and boiling points

Double Bond Single bond hydrocarbons end in “-ane” like Propane Double Bond hydrocarbons end in “-ene” or “-yne” like Ethene.

Hydroxyl Group Hydroxyl group is a “OH” compound used for substitute for hydrogen atom in hydrocarbons Alcohol is a substituted hydrocarbon that contains one or more hydroxyl group Ethanol is produced natually by yeast when they consure sugar stored in corn, wheat and barley Methanol (poisonous) Ethanol

Polymers vs. Monomers Polymer: A very large molecule (millions of atoms) made of a chain of many smaller molecules. Monomer: Smaller molecule – the links that make up the chain

What are some natural Polymers?

What are some examples of Natural Polymers? Wool Cotton Silk DNA & RNA Protein Carbohydrates Starch

What are some man made Polymers?

What do plastics and cells in your body have in common? They are both made of carbon compounds

What are the four types of polymers found in all living things? Carbohydrates Lipids Proteins Nucleic Acids ????????

Carbons can form four covalent bonds They can also bond to each other in changes and ring shaped groups

What are composites Composites combine two or more substances as a new material with different properties

What is the simplest carbohydrates? Sugar One of the most important sugars in your body is glucose C 6 H 12 O 6 Glucose is also known as “blood sugar” because it is circulated through out your body

Starch is a form of complex carbohydrate. Which food contains lots of starch? Rice Potatoes Bread Cereal Pasta Wheat

Carbohydrates A carbohydrate is an en______ rich organic compound made up of car______, sugar and oxygen. Carbohydrates are used to fuel our body Sug____ and starches are examples of carbohydrates. ergy ars bon

Lipids = Fat Lipids are ene______ rich organic compounds made of car______, hydrogen and oxygen Lipids are used by our ner____ cells Fats, oils and waxes are all lipids rgy bon ve

Proteins Proteins are large organic molecules made of car_____, hydrogen, oxygen, nitrogen. Proteins are used to build mus_____, skin and bone cells Food that are high in protein include me___, eggs, fi_____, nuts and beans at sh bon cle

Enzymes An enzyme is a type of protein that speeds up a che______ reaction in a living thing. For example, enzymes in your saliva speed up the dige______ of food. mical stion

Nucleic Acids Nucleic acids contain the inst________ that cells need to carry out all the functions of life. DNA and RNA are Nucleic Acids ructions
