Macromolecules. L ipids, proteins, and nucleic acids . Lipids!. Lipids are commonly called fats and oils. They are mostly made up of Carbon and Hydrogen, with less Oxygen than carbohydrates have. They are linked by non-polar covalent bonds

Lipids, proteins, and nucleic acids
Lipids are used for energy storage, insulation, and protective coatings.
Proteins are large, complex polymers composed of carbon, hydrogen, oxygen, nitrogen, and sulfur.
Hair, spiders web, tendon and ligament fibers
Hemoglobin, carries oxygen from your blood to your lungs and other parts of your body
Proteins are made of amino acids.
There are 20 amino acids.Of all of life’s molecules…….
Cells link amino acids together by dehydration synthesis
A water molecule is removed
Carbon and Nitrogen form a bond
The covalent linkage is a peptide bond
The product is called a dipeptide – 2 amino acids
Additional amino acids can be added by using dehydration synthesis
This creates polypeptides
The protein’s dependence on shape becomes clear when the protein is altered in some way
The quaternary structure of proteins is the relationship among multiple polypeptides of a protein
A nucleic acid is a complex macromolecule that stores cellular information in the form of a code.
