Teens & Depression. â 1 Depression is a serious problem today and one of the nationâs leading killers of teenaged boys when the number of cases of suicide it generates are factored into the equation.
The first organic molecules were probably very simple carbon-based molecules made of few atoms. These molecules then combined with other simple molecules to form more complex molecules. Over many years and probably trillions and trillions of chemical reactions, more complex molecules, and more stable molecules, formed.
At the base of all organic molecules is the element carbon, whose versatility provides the key to all biomolecule structures. In most organic molecules, a linked chain of carbon atoms forms a backbone to which other atoms attach. The unique number and arrangement of bonds between carbon atoms creates a structurally diverse set of organic molecules in nature.
