What is the typical extracellular concentration of glucose in mg/dl?

The typical extracellular concentration of glucose in humans is around 90 mg/dl. This concentration reflects the normal fasting blood glucose levels found in most healthy individuals. Monitoring glucose levels is crucial for various physiological processes, including cellular respiration and energy production, making it an important aspect of metabolic homeostasis.

In the context of glucose metabolism, maintaining this level is vital for supplying energy to tissues, especially the brain and red blood cells, which rely heavily on glucose as their primary energy source. Variations from this normal range can indicate metabolic disorders, such as hypoglycemia (low glucose) or hyperglycemia (high glucose), which are significant in clinical practice. Understanding these values is essential for nursing practice, particularly when assessing patients for conditions like diabetes mellitus or other endocrine disorders where glucose regulation is affected.
