Chemical Composition of Organisms
• Types of Substances:
Organic:
o Carbohydrates
o Lipids
o Proteins
o Nucleic acids
Inorganic:
o Water
o Minerals
o Carbon-based elements are the most abundant.
• Biogenic elements
—chemical elements that make up organic molecules (substances). (C, H, O, N, P, S)
o Carbohydrates consist of: C, H, O
o Lipids consist of: C, H, O
o Proteins consist of: C, H, O, N, S
o Nucleic acids consist of: C, H, O, N, P
• Monomers and polymers
Monomers:
o Constituent parts of polymers (macromolecules).
