1. Macromolecules
Anatomy

4. Our Body Is…. Oxygen 65% Carbon 18.5% Hydrogen 9.5% Nitrogen 3.2%
Calcium, Phosphorus, Potassium, Sulfur, Sodium, Chlorine, Magnesium, Iodine, Iron
Less than 3% each

5. Organic Compounds Made of Carbon!
4 main types of macromolecules/organic compounds
Carbohydrates
Lipids
Proteins
Nucleic acids

6. Carbohydrates Monosaccharides- simple sugar Disaccharide- double sugar
Glucose, fructose, galactose
Disaccharide- double sugar
Sucrose (made of glucose + fructose)
Polysaccharides
Starch, glycogen

8. Carbs in the Body! Small amounts are used for structure
Used mainly for energy (can be stored as fat if you don’t need it)
Can be attached to external structures as ID tags

9. Lipids
Insoluble in water but dissolve in organic solvents (alcohol and ether)
Triglycerides, phospholipids, steroids, eicosaniods

11. Steroids Cholesterol Plays a role in arteriosclerosis
hardening (and loss of elasticity) of medium or large arteries
Important and vital to have to maintain homeostasis

13. Eicosanoids In cell membranes
Important for blood clotting, inflammation, labor contractions, regulating blood pressure

15. Proteins Basic structural material Made of amino acids
Enzymes, hemoglobin, muscle

16. Fibrous Proteins Structural proteins Strandlike
Collagen, keratin, elastin, contractile proteins of muscle

17. Globular Proteins Functional Proteins Compact Immune
Regulate growth/development
Catalysts

18. Denaturation Fibrous are more stable than globular
Can denature because
Acidity
Heat

20. Nucleic Acids
A,G,T,C,U
DNA and RNA
