What is one consequence of eating unhealthy food and being physically inactive?

Objectives (write in cues section)

1. Describe why macromolecules areimportant for living organisms.

2. List 4 types of macromolecules.

3. Compare the structures (struc.) and functions (func.) of different (diff.) types of macromolecules.

Where do we get our energy?

• Food = fuel

• Sun’s Energy

Captured & stored by green plants

Passed along in fruits & seeds to animals

Animals eat other animals

Why do we need food?

• Provides energy for all of the body’s functions:1) beating of the heart

2) elimination of wastes

3) transmission of electrical (elec.) & chemical (chem.) signals in the nervous system

Why do you care?

• Poor food choices, dietary habits, and physical inactivity lead to:

- Cardiovascular disease (CVD)- Obesity- Diabetes- Certain types of cancer (colon, etc)

• Need 40 different nutrients to maintain good health• Need a wide variety of foods

Organic Nutrients = produced and made by living things

AKA (also known as): - Macronutrients - Biomolecules

Latin Roots: (write in cues section of notes) 1) Macro = large

2) Bio = life

Macromolecules

Monomer vs Polymer

• Monomer = one piece•Latin Root: mono = one

• Polymer = many pieces•Latin Roots: poly = many

4 Types of Macromolecules

1. Carbohydrates (aka Carbs)2. Lipids (aka Fats)3. Proteins4. Nucleic Acids

CARBOHYDRATES

• Made up of only 3 elements: CHO1. Carbon2. Hydrogen3. Oxygen

• Have a hexagonal shape

One ring = monosaccharide

(Latin Root: Mono = one)

String a bunch of monosaccharides together =

Polysaccharide

(Latin Root:poly = many)

Two saccharides (2 rings) = disaccharide

(Latin Root: di = two)

WHY ARE CARBOHYDRATES IMPORTANT?

• Body’s major source of steady energy• 50% (45 – 60%) of daily caloric intake•Aids the body in removing fats• Reduces blood cholesterol & blood glucose• Fiber decrease risk of colon cancer

WHAT FOODS CONTAIN CARBOHYDRATES?

• AKA: Sugars & Starches• Complex Carbohydrates

Food sources: breads, cereals, pastas, grains• Dietary Fiber

Food Sources: oats, fruits, barley, legumes, wheat, cereal, vegetables, and the skins of fruits

• Simple SugarsFood Sources: milk, fruit, honey, cookies, candy

Lets make a foldable for review.

Front: Make a riddle for Carbohydrates.(folds down)

Bottom flap: draw the structure. (folds up)

Mid flap: biomolecule name and importance.

Step 1 Step 2 Step 3

When your foldable is complete, please tape or glue it to the blank sheet of paper.

Warm Up

Thursday September 5, 20131.List the elements found in carbohydrates.2.Draw a picture of a carbohydrate.

LIPIDS• Contain 3 elements: CHO

1. Carbon2. Hydrogen 3. Oxygen

• Forms a chain

Why are lipids important?

1. Storage of energy (2ndary source)

2. Satisfies appetite

3. Transports vitamins A, D, E, & K

4. Thermal insulation

5. Mechanical Protection (surrounds vital organs)

6. Waterproofing (Ex: ear wax)

WHAT FOODS CONTAIN LIPIDS?

AKA fats and oils

Types of Fats:1. Unsaturated (good)

Food Sources (derived from plant products): olives, peanuts, corn and canola oils

2. Saturated (bad)Food Sources (derived from animal products): meats, lard, cream, butter, cheese, and whole milk

3. Trans FatsFood Sources: typically do not occur naturally in plant or animal products

When your foldable is complete, please tape or glue it to the blank sheet next to your carbohydrate foldable.

PROTEINS

Composed of 4 elements: CHON1. Carbon2. Hydrogen3. Oxygen 4. Nitrogen

Amino Acid = building block of proteins

PROTEINSThere are 20 different amino acids

-11 are produced by the body (non-essential)

- 9 are not made by the body (essential)

WHY ARE PROTEINS IMPORTANT?1. Growth, maintenance, & repair of all body tissues

(muscles, blood, bones, internal organs, skin, hair, & nails)

2. Needed in the synthesis of enzymes, hormones, and antibodies

Note: Enzymes = proteins that regulate chemical reactions in your body

Synthesis = to create

3. Proteins form some of the entrances and exits through the cell.

WHY ARE PROTEINS IMPORTANT?

TOO MUCH PROTEIN?

Excess protein can:1. Damage the kidneys 2. Increase calcium excretion 3. Affect bone health4. Inhibit muscle growth 5. Inhibit endurance performance

- Make up 25% (15-35)% of daily calories-Include:

- All Meats:- Beef- Pork- Poultry (chicken, turkey, duck)- Fish (salmon, trout, flounder, etc)

- Seeds & Nuts- Legumes/Beans (black, kidney, pinto, etc)- Eggs- Dairy products (milk, cheeses, yogurt)

***Lots of sources are high in saturated fat***

1.What is another name for lipid?2.What is an amino acid?

NUCLEIC ACIDS

Composed of 5 elements: CHON-P1. Carbon2. Hydrogen3. Oxygen 4. Nitrogen5. Phosporus

Nucleotide = building block of nucleic acids

Why are NUCLEIC ACIDS Important?

• Make up genetic material (DNA and RNA)

• 4 types nucleic acids:

1. Adenine (A)

2. Guanine (G)

3. Cytosine (C)

4. Thymine (T)

WHY ARE NUCLEIC ACIDS IMPORTANT?

1. Used to make proteins

2. Carry heredity information from generation to generation
