The hémin molecule has essentially the same nucleus, but different side chains. It contains two vinyl groups, which are hydrogenated to ethyl groups in chlorophyll. The latter also contains an ...

Plants use quantum mechanics to optimize photosynthesis, inspiring new artificial light-harvesting technologies.

They are an important food for other river life such as small animals and freshwater shrimp. The chlorophyll molecule allows algae to absorb energy from light; a process known as photosynthesis. Thus ...

Half of the chlorophyll molecule has been synthesized so far, but certain parts of the other half still present problems, Woodward explained. The scientists are now trying to perfect a compound ...

Jürgen Hauer explains: “When light is absorbed in a leaf, for example, the electronic excitation energy is distributed over several states of each excited chlorophyll molecule; this is called a ...

The idea suggests early life forms used a different molecule for photosynthesis than today’s chlorophyll. NASA-backed research supports this hypothesis, with scientists like Dr. Edward ...
