PPT-Life’s Structure: Building the Molecules

All life uses 6 major elements If we survey the molecules from which life is constructed we find six that are found in all living things and have often been described as the building block elements of . (14.7). Conjugated molecules have alternating carbon-carbon single and double bonds. π-electrons can move freely along all carbon atoms in the conjugated portion of the molecule. The 1D PIB model can be crudely applied to the energy states of a polyene (e.g., β-carotene). J. . Aldegunde. , . Piotr. . Żuchowski. and Jeremy M. . Hutson. University of Durham. EuroQUAM. meeting.
