Chemical bonds in Biology
When we studied the levels of organization of living matter, we saw that matter is made up of atoms that are joined by bonds to form more complex structures, molecules, essential for the functioning of living beings.
We will now recall the most important links in biology, which will be referenced throughout this course.
A molecule is produced by the stable union of two or more atoms. The formation of the bonds that exist between the atoms that make up a molecule requires less energy than is necessary to keep the atoms apart. To break these bonds it is necessary to apply energy. If a large amount of energy is required to break the bond, the bond is called a strong bond. If small amounts of energy are required, the bond is a weak bond.
We distinguish two types of links:
