Friday 9/21

• Finish molecule building

• Macromolecule presentation

Chemistry Basics

• Organic: Carbon-containing

• Basic unit of life is a cell; all organic

Chemistry Basics

• Atoms made of protons, neutrons, electrons

• Electrons used for bonding

• Carbon has 4 valence electrons—> can form 4 bonds

Chemistry Basics

• Carbons atoms covalently bond (share electrons) with other atoms

• Can form branches, chains, or rings

Macromolecules

• Most are polymers made of repeating monomers

• Monomers are joined by condensation reactions (dehydration synthesis) = water molecule is removed

• Ex. carbohydrates, proteins, lipids, and nucleic acids

Carbohydrates

• Made of C, H, O

• Used as main sources of energy for humans

• Found in fruits, vegetables, grains, pasta, bread, sugar

• Types

• Monosaccharides: simple sugars (ex. glucose)

• Disaccharides: double sugars (ex. sucrose)

• Polysaccharides: complex carbs (ex. starch, cellulose/fiber)

Proteins

• Made of C,H, O, N and sometimes S and P

• Used mainly for structure and support, can also be source of energy, enzymes

• Found in meat and dairy products, soy beans, and peanut butter

• Monomers are amino acids joined by peptides bonds (condensation reactions)

Lipids

• Made of C, H, O

• Used for long-term energy storage, hormone regulation, insulation

• Produce more than twice the energy of carbs and proteins

• Found in meat and dairy products, plant oils

• Made of fatty acids and glycerol

Types of lipids

• Saturated vs. unsaturated fats

• Saturated - has the maximum number of Carbon/ Hydrogen bonds

• Unsaturated - contains one or more double bonds

Monday 9/24

• Notes

• Quiz info

• Food lab Demo

• Building if time permits

Monday 9/24

• Learning Target

• Student can describe the structure and function of biomolecules

Review

• Monomers—> Building blocks

• Polymers—> Large molecule made from monomers

• Other names: Macromolecules, biomolecules, etc.

• Types of polymers: lipids, proteins, carbohydrates

Nucleic Acids

• C, H, O, N, P

• Made of a sugar, phosphate, and nitrogen base

• Monomer: Nucleotide

• Make up DNA/RNA

• Found in ALL living things!

Review

• Metabolism— Total of all chemical processes in the body

• Breaking down vs. building up

Getting energy from Creating macromolecules

food molecules = respiration from monomers

Hydrolysis vs. Condensation

• Water added

• Bonds broken

•

• Sometimes called dehydration

• Water formed

• Bonds made

What is energy?

• ATP

• Unit of energy - Joule

• In class we will refer to the Calorie as the amount of available energy in a food.

Opposite reactions

• Dehydration synthesis and hydrolysis are opposite reactions.

• “Coupled” - occur together

• Ex. Making and breaking ATP for energy

Food Lab

• Get out a sheet of paper - Label Food lab

• Groups 3 - 4

• Testing 6 foods: Cheerios, cottage cheese, carrots, chips, tofu, applesauce

• Testing for simple sugars, starches, fats, proteins,

• In-depth procedure - DEMO

• Clean-up

Procedures

• Always use DI water - never spray at people! = kicked out of lab and reduction of lab points

• Clean regularly

• Results - be clear in interpreting (paper towel)

• Label group (something special, and food) at the top!

• Less food + more ground = better result

Tuesday 9/25

• Have out paper for Nutrition lab data table

• Nutrition lab
