Biomolecules are the chemical components of life, including the four major types of biological macromolecules, proteins, carbohydrates, lipids and nucleic acids, as well as smaller molecules, such as metabolites, neurotransmitters, vitamins and hormones. With its rich chemical database, Wolfram|Alpha has information on structural diagrams and atomic structures, chemical properties such as hydrophobicity and the impact of biomolecules on human life through toxicity and the roles of the chemicals in drugs.
