Definition
nutrient role held by a material entity that is metabolized in cellular pathways to generate adenosine triphosphate, reducing equivalents, or other forms of metabolic energy required for growth, maintenance, or biosynthesis
Explanatory Notes
In manufacturing and culture systems, glucose and glutamine are the most common energy substrates supporting mammalian cell growth and productivity. Depending on process conditions, other compounds such as lactate, pyruvate, or specific amino acids may also serve as energy sources. The type and concentration of energy substrates influence cell metabolism, product quality, and process performance, making their control a key part of medium and feed design.
Examples
- role held by glucose serving as the main energy substrate in DMEM (Dulbecco’s Modified Eagle’s Medium) or RPMI 1640 cell-culture media; role held by glutamine acting as both an energy and nitrogen source in chemically defined CHO-cell feeds; role held by glycerol used as an energy substrate in E. coli fermentation media

Primitive Class
This class is declared primitive and it does not have necessary and sufficient condiftions defined.
Primitive Rationale
This term is expected to remain primitive as the detailed treatment of biochemical processes is outside of the current scope of IOF. Other biological and chemical ontologies should be used for these purposes
