Since its independence in 1956, Sudan has been bedeviled by a succession of civil wars and political instability. The Darfur conflict should be seen as part of these larger, ongoing series of Sudanese crises, with one conflict spilling from one part of the country to another.
the general term is cofactor, but more specifically, if the cofactor is an organic molecule, it is called a coenzyme.
Cofactors can be subdivided into either one or more inorganic ions, or a complex organic or metalloorganic molecule called a coenzyme; most of which are derived from vitamins and from required organic nutrients in small amounts. A cofactor that is tightly or even covalently bound is termed a prosthetic group.Some sources also limit the use of the term cofactor to inorganic substances. An inactive enzyme without the cofactor is called an apoenzyme, while the complete enzyme with cofactor is called a holoenzyme.ofactors can be divided into two broad groups: organic cofactors, such as flavin or heme, and inorganic cofactors, such as the metal ions Mg 2+ , Cu + , Mn 2+ , or iron-sulfur clusters. Organic cofactors are sometimes further divided into coenzymes and prosthetic groups.
