Neurocosmetic activity of chitin nanofibrils

The Earth, as well as the human body is, in fact, a biological continuum of many different organisms and organs, all made by cells living together in the same environment. No one can survive alone. Animals depend on energy produced during plants’ photosynthesis, and, in turn, plants depend on carbon dioxide, produced from animals as well as on nitrogen, coming from bacteria. Thus plants, animals, and microorganisms regulate the entire biosphere maintaining the general condition of life (Fig. 1).² However, any form of life is based on cells which, working by macromolecules as DNA, RNA, and deoxynucleic acids are activated by special proteins, named enzymes.

The enzymes, codified by genes act as catalysts of different cellular metabolic processes, in turn controlled by genes that codify the proteins’ synthesis.

 In this complex machinery, DNA molecules are responsible for the cellular replication, while the RNA polymers act as messenger: they transport from DNA all the information codified for the synthesis of enzymes (Fig. 2). This information represents the connection between  metabolic and genetic structures of all the cells involving the nervous, immune, cutaneous, and endocrine systems (NICE), according to traditional Chinese medicine also (TCM).
