1. 2.2B Macromolecules
Are you what you eat?

2. Organic Compounds Organic compounds- contain the element carbon
Are essential to all known life on Earth
make up organisms and carry out life processes
Without carbon, life as we know it could not exist.
carbon atoms can form a tremendous variety of very large and complex molecules.

3. Macromolecules
Large organic molecules that are composed of smaller organic molecules linked together.
There are four classes of macromolecules: carbohydrates, lipids, proteins, and nucleic acids.

5. Carbohydrates Function-primary source of energy
Elements it contains- Carbon, Hydrogen, Oxygen
Examples- Pasta, cereal, fruits, vegetables

6. Lipids
Functions- long term energy storage ,component of cell membranes
Elements it contains- Carbon, Hydrogen, Oxygen
Examples- Fats, oils, waxes, steroids, hormones
A gram of lipids supplies more than twice as much energy as a gram of carbohydrates or proteins.

7. Types of Lipids Triglycerides-main form of stored energy in animals.
Fat
Phospholipids-major component of cell membranes
Steroids (or sterols)
Important part of cell membranes
Other vital roles in the body such as male and female sex hormones

8. Proteins
Functions- provides cell structure, Speed up chemical reactions (enzymes)
Elements it contains- Carbon, Hydrogen, Oxygen, Nitrogen, Sulfur
Examples- Muscle, enzymes
Proteins are made of smaller units called amino acids
There are 20 different common amino acids needed to make proteins.
Humans are able to synthesize all but nine

9. Protein

10. Nucleic Acids Function- Carry genetic information
Elements it contains- Carbon, Hydrogen, Oxygen, Nitrogen, Phosphorus
Examples- DNA, RNA
Made of smaller units called nucleotides
Living cells and viruses are made from these
This is how our genetic material is passed… like a blue print!
