1. Macromolecules

2. Carbon
One of the most important elements found in living things
Has 4 valence electrons which means it can form 4 bonds with other carbon atoms or other elements such as hydrogen (H), oxygen (O), phosphorous (P)

3. Lipids Does not have monomer or polymer
Atoms: carbon, hydrogen and a few oxygen
Does not have monomer or polymer
Main parts are called fatty acids
1. They make up the cell membranes
2. Store/provide energy

4. Nucleic Acids Monomer: nucleotides Polymer: DNA(double strand)
Atoms: carbon, hydrogen, oxygen, nitrogen, and phosphorous.
Monomer: nucleotides
(3 parts to a nucleotide: sugar,
phosphate group, and a
nitrogenous base)
Polymer: DNA(double strand)
RNA (single strand)
They store and transmit instructions for building and maintaining a living thing
