Substrate Preference

Meaning

Substrate Preference describes the inherent tendency of an enzyme system or an entire tissue to preferentially utilize one metabolic fuel source over another for energy production or synthetic processes. This preference is not static but is dynamically regulated by hormonal status and substrate availability within the systemic environment. Understanding this metabolic choice is key to optimizing tissue function, such as in cardiac or skeletal muscle. The cell makes a fuel choice.
