Document Summary
Functional groups are the components of organic molecules that are most commonly involved in chemical reactions (considered decorations) Each functional changes the characteristic of a chemical reaction. Atp (adenosine triphosphate) is the primary energy-transferring molecule in the cell (rechargeable battery) 7 functional groups that are most important in the chemistry of life: Nucleic acids connect further to form macromolecules. Atoms connect to build small organic molecules and the small organic molecules. A polymer is a long molecule consisting of many similar building blocks. The small building-block molecules are called monomers. Connecting of monomers to form a macromolecule if often accomplished with a series of condensation reactions. In a condensation reaction (also called a dehydration reaction), the bonding of two monomers is accompanied by the loss of the water molecule. Condensation reactions often include enzymes, which are macromolecules that speed up the dehydration process.
