Study of compounds that contain bonds between carbon atoms
Inorganic chemistry: study of all other compounds
ORGANIC CHEMISTRY
![Page 3: ACTIVITY #6: ORGANIC MOLECULES. Study of compounds that contain bonds between carbon atoms Inorganic chemistry: study of all other compounds ORGANIC.](https://reader034.fdocuments.net/reader034/viewer/2022051620/56649f275503460f94c3f41f/html5/thumbnails/3.jpg)
Has 4 valence electrons Allowing it to form up to
four bondsOne carbon atom can
bond to another, giving it the ability to form chains that are almost unlimited in length Carbon-carbon bonds
can be single, double or even triple covalent bonds
Chains of carbon atoms can close up on themselves to form rings
WHY IS CARBON SO SPECIAL?

OrganicUsually defined as
compounds which contain carbon with hydrogen May contain additional
elements as wellProduced only by living
things Biotic
Range from simple to very complex
Contain strong, covalent bonds
Examples: CH4, C6H12O6, SUGARS, PROTEINS, FATS, OILS, DNA
InorganicUsually defined as
compounds that do not contain carbon with hydrogen May contain just carbon
Often can be formed in the non-living environment Abiotic
Can also be made by/found in living things
Examples: H2O, NaCl, O2, NH3, CaCO3, CO2

The exception: Lipids are not composed of monomers and polymers. Instead, they take different forms.

2 major chemical processes (metabolic reactions) occur to build up or break down organic molecules into larger or smaller units
These reactions occur to build and break all four types of macromolecule (carb, lipid, nucleic acid, and protein) Dehydration synthesis Hydrolysis
BUILDING AND BREAKING DOWN MACROMOLECULES
![Page 18: ACTIVITY #6: ORGANIC MOLECULES. Study of compounds that contain bonds between carbon atoms Inorganic chemistry: study of all other compounds ORGANIC.](https://reader034.fdocuments.net/reader034/viewer/2022051620/56649f275503460f94c3f41f/html5/thumbnails/18.jpg)
Chemical reaction where a large molecule is formed/synthesized from smaller molecules by taking away a water molecule
DEHYDRATION SYNTHESIS
![Page 19: ACTIVITY #6: ORGANIC MOLECULES. Study of compounds that contain bonds between carbon atoms Inorganic chemistry: study of all other compounds ORGANIC.](https://reader034.fdocuments.net/reader034/viewer/2022051620/56649f275503460f94c3f41f/html5/thumbnails/19.jpg)
Chemical reaction where a large molecule is broken down/hydrolized into smaller molecules by adding a water molecule
HYDROLYSIS
disaccharide + water → yields monosaccharide + monosaccharide
