What is Dehydration Synthesis?
|
. The process by which larger molecules are formed by the removal of water from two smaller molecules.
|
|
|
What is Hydrolysis?
|
. The process by which a larger molecule is broken down inot two smaller molecules. Water is taken up at the broken bond site.
|
|
|
What are organic Compounds?

|
|
What are inorganic compounds?
|
Compunds that don't contain linked carbon atoms.

|
|
What are the types of Carbohydrates?
|
Disaccharides- formed by the joining of 2 monoshaccharieds through Dehydration synthesis.
