Dehydration+Synthesis+and+Hydrolysis

Sugar molecules can be bonded togethter by a process callled dehydration synthesis. Synthesis means putting together and dehydration means removing water. thus dehydration synthesis means putting together by removing water. When sugar molecules are bonded together the bond forms where an OH group is present in each molecule. At this point 1 OH combines with the H from the other OH, forming a molecule of water. The 2 molecules are then joined through the remaining O. In living cells dehydration synthesis is brought about by the action of enzymes. It is an important process in making the many complex organic compunds that an organism needs.
 * Dehydration synthesis**

Example:The formation of maltose from two glucose molecules

Disaccharides and polysaccharides may be broken apart by the process called hydrolysis. in this type of reaction a water molecule reacts with a chain of sugar molecules to produce 2 simple sugars is broken, when hydrolysis occurs, a bond between 2 simple sugars is broken and the original OH groups are restored. Hydrolysis can be repeated on long chains until an entire polysaccharide has neem split into its simple sugars. In living organisms, the process of hydolysis, like dehydration synthesis, is brought about by the action of differnent enzymes.
 * Hydrolysis**

Example: A reaction between amino acids in order to release proteins and water as products.
