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. Carbohydrates AKA- sugars
Atoms: carbon, hydrogen and oxygen
Monomers: monosaccharide
Polymer: polysaccharides.
1)They are the main source of energy for all cells
2)They may also provide structural support/build bodies of plants

4. Proteins Monomers: amino acid Polymer: polypeptides
Atoms: carbon, hydrogen, oxygen, nitrogen
Monomers: amino acid
Polymer: polypeptides
They have many functions including:
1) controlling rate of reactions/ regulate cell processes
2) form muscles, bones, hair
3) transport substances
4) fight disease 4

5. Lipids Does not have monomer or polymer
Atoms: carbon, hydrogen and a few oxygen
Does not have monomer or polymer
Main parts are called glycerol and fatty acids-long chains of carbon and hydrogen +
1) They make up the cell membrane
2) Store energy

6. 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 directions for building and maintaining a living thing
