glutelin

Glutelin is a highly specialized biochemical term used almost exclusively in the fields of cereal chemistry and plant biology. It describes a specific class of proteins that serve as the primary energy and nitrogen reserves for developing seeds.

In a laboratory or academic context, the term is often contrasted with other grain proteins like albumins or globulins based on their solubility profiles. It is typically treated as a mass noun when referring to the protein substance in general, though it can be used countably when referring to specific types or varieties of the protein.
