Organic vs. Inorganic Molecules
If you understand these building blocks, future units will be a breeze!
Types of Molecules
• Molecules are elements that are bonded together. There are two types of molecules. – Organic – living or once living– Inorganic – nonliving
Types of Molecules• Remember the elements carbon and hydrogen?
Well, when these elements are found together, they make an ORGANIC molecule.
• Organic = C + H together
• Inorganic = no C + H together
SO, everything that is living is ORGANIC, it contains C and H.
Organic or Inorganic?
Inorganic Molecules
• There are millions of inorganic molecules, but there are only a few you MUST know
• H2O = • O2 =
• CO2 = • NH3 =
water
carbon dioxide
oxygen
ammonia
Organic Molecules
• There are 4 types of organic molecules.
• Meaning, EVERYTHING that is living is made up of a mixture of these 4 substances.
– Proteins – Carbohydrates (Sugars)– Lipids (Fats)– Nucleic Acids (DNA)
You are what you eat!
We do not eat inorganic materials, we eat
organic. Protein, carbs, and fats are our nutrition!
Organic Molecules
• Organisms either consume or produce their nutrition. However these molecules need to be broken down so they can be used for various needs.
Complex Molecules:
Proteins
Carbs
Lipids

Proteins
• The building blocks of proteins are amino acids.
• Proteins are important for many reasons. – Enzymes – chemical reactions– Body growth and repair What kinds of
protein do we eat?
Carbohydrates• The building blocks of carbohydrates are simple
sugars.
• C6H12O6 is sugar. Because of sugars structure, it is represented as in science.
• Carbohydrates provide:– Energy
What kinds of carbs do we eat?
Lipids
• The building blocks of lipids are fatty acids.
• Lipids are important because they:– Provide stored energy– Make up the cell membrane
What kinds of fat do we eat?
Nucleic Acids
• Nucleic Acids make up the organisms heredity. It is the DNA, or the genetic code for all living things.
• Yes, every living organism from a sponge to a whale has DNA.
