Chitin is a natural biopolymer widely found in fungi, arthropods,
mollusks and other organisms. It is composed of
N-acetylglucosamine and has important biological functions and
application values. The production process of chitin includes two
main links: biosynthesis and extraction. The biosynthesis process
is the process of chitin naturally forming in the body, while the
extraction process is to separate it from the organism containing
chitin.
Chinese scientists recently published their research results in
the journal Nature, revealing the complete process of chitin
biosynthesis. The study found that chitin synthase transfers the
sugar group on the donor substrate to the acceptor chitin sugar
chain, and the newly generated chitin sugar chain is released to
the outside of the cell through the transmembrane transport
channel on the cell membrane. Finally, the released chitin chain
spontaneously assembles into chitin nanofibers.
The product characteristics of chitin include its physicochemical
properties and biological activity. Chitin is usually expressed
in terms of its N-amino acetylation degree (DA) and the degree of
polymerization (DP) of the sugar unit structure to express its
chemical or physical characteristics. The larger the DA
value, the greater the percentage of acetylation of free amino
groups on the chitin skeleton; the larger the DP value, the
greater the chitin molecule is composed of more monosaccharide
molecules and the larger the molecular weight. Chitin is a white
amorphous substance, odorless and tasteless, soluble in
dimethylacetamide or concentrated hydrochloric acid containing 8%
lithium chloride, but insoluble in water, dilute acid, alkali,
ethanol or other organic solvents. Chitin and its derivatives
have a wide range of applications in medicine, chemical industry,
health food and other fields, such as additives for cosmetics and
functional foods, preparation of photographic emulsions, etc. In
addition, chitin synthase, as a molecular target for pesticides,
helps to create efficient, safe and eco-friendly pesticides,
which is of great significance to agricultural production.
