Macromolecules
Lipids
Triglycerides
Carbon, Hydrogen, and Oxygen
Fats, oils, phospholipids, steroids, and waxes
They come in both saturated and unsaturated lipids, they're non-polar, and their structure is both hydrophobic and hydrophilic.

Carbohydrates
Monosaccharides
Carbon, Hydrogen, and Oxygen
Gives us quick energy, helps with energy storage, and contributes to the structure of living things
Sugars (such as lactose and glucose), starches, cellulose, and glycogen
They have a CHO ratio: for every carbon and oxygen, there are two hydrogens.

Proteins
Carbon, Hydrogen, Oxygen, and Nitrogen
Amino Acids
Builds body structure, makes up enzymes, and assists with hormones (insulin) and movement (muscles)
Twist into three dimensional shapes and covalent bonds link amino acids together
Hemoglobin, insulin, lactase, maltase
