This property allows for the formation of complex organic molecules such as carbohydrates, lipids, proteins, and nucleic acids which are essential for life processes. Uranium is a radioactive heavy metal not involved in the fundamental structure of life. Silica is a compound (SiO₂) mainly found in rocks and sand and not a basis for life. Aluminum is a metal also not a fundamental building block for life - forms.
