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.
Organic molecules are hydrocarbon molecules. There are four major types of organic molecules: Proteins, Lipids, Carbohydrates and Nucleic Acids. Organic molecules are mostly made of chains of carbon atoms with hydrogenâs attached. On the right, we see the basic structure of an organic or hydrocarbon molecule (C-H-C-H). A carbon atom has four electrons in its outer orbit and these four valence electrons are shared with other atoms.
