On creatures that use citrate as their only carbon source
The husband of organisms is a wonderful existence in the world. Today, there is a class of organisms that are unusual in that they can survive and multiply by using citrate as their only carbon source.

The husband of carbon sources is like grain and grass to the military, which provides the foundation for life activities and the source of materials that build biological organisms. As the saying goes, organisms consume carbon sources through various channels, but such organisms are only in love with citrate.

Looking at their survival state, in the environment, if only citrate is the only carbon source, other kinds of carbon sources are absent, and such organisms can thrive. There must be a delicate mechanism in its cells, which can enable citrate to enter the cell and undergo a series of biochemical reactions, such as cooking to relieve cattle, or as a source of energy, driving the endless life activities; or as a raw material for building cell structures and synthesizing biological macromolecules, so that cells can grow, grow, and be passed down.

And biological evolution, to survive the fittest. Such organisms can use citrate as the only carbon source, which must be honed for a long time. Or due to environmental changes, carbon sources are scarce, and only citrate exists. For survival, organisms gradually get used to it, accumulate genetic variation, and finally obtain this unique ability to survive. Its ability also has a unique position in the ecosystem, or participates in the material cycle, so that citrate is transferred between organisms and the environment, maintaining the balance of ecology; or affects the life and livelihood of other organisms, with its unique metabolites, adding brilliance to the ecology.

Eh! Organisms use citrate as the only carbon source. Although it is small, it can be seen that the wonder of life and the wonders of nature are endless. Waiting for our generation of researchers to investigate it in depth, in order to uncover the mystery of life, for the prosperity of science and the blessing of mankind.
