INORGANIC AND
ORGANIC
COMPOUNDS
Organic Compounds
- Must have carbon (C) atoms
and hydrogen (H) atoms.
- There are two exceptions: CO2
and CaCO3 (these are organic
even though they don’t have H)
- Come from living things
Inorganic Compounds
- Compounds that do not have
carbon (C) atoms.
- Can have more than one
hydrogen (H) atom.
- Come from nonliving things.

Organic Compounds
1. Carbohydrates
- Made of carbon, oxygen, and
hydrogen
- 50%-70% of our total body
intake
- Also made in
photosynthesis
Organic Compounds
2. Proteins
Polymers of molecules called
Amino Acids.
- Important in building, repairing
and maintaining body
tissues.
Organic Compounds
3. Lipids
- Include fats, oils, waxes,
phospholipids and steroids.
- Greasy to the touch and are not
soluble in water.
- Components of cell membrane.
- Supplies taste and flavor to food.
Inorganic Compounds
1. Water
- Most important inorganic
compound.
- 65% of our body weight is
water.
Inorganic Compounds
2. Acids
- Latin word “acidus” – sour
- Compound that yield hydrogen
ions (H+) in solution.
- Turn blue litmus
to red.
Inorganic Compounds
3. Bases
- Have properties that contrast with
those of acids.
- Taste bitter and slippery
- Compound that produces hydroxide
(OH+) when dissolved in water.
- Turns red litmus paper to blue.
Inorganic Compounds
4. Salt
- Formed when an acid and
base react.
- Provide many essential ions
for body processes.
