Corrin
Corrin (pronounced: /ˈkɒrɪn/) is a type of chemical compound that forms the core of several biologically important molecules, including vitamin B12.
Etymology
The term "corrin" is derived from the word "corrinoid," which was first used to describe compounds with structures similar to that of vitamin B12. The "-oid" suffix was later dropped, and the term "corrin" was adopted.
Definition
Corrin is a macrocyclic compound consisting of four pyrrole rings linked by methine bridges. It is the central part of several important molecules, including vitamin B12, which is also known as cobalamin due to the presence of a cobalt atom at the center of the corrin ring.
