It serves as the primary energy source for humans. Every pathway, every form of metabolism has glucose involved with it. Glucose also serves as the backbone for many important molecules in the body. Glucose is also further uses to make disaccharides and polysaccharides. The metabolism of glucose or cellular respiration yields a lot of ATP in the human body. Since glucose serves such important functions, understanding the biochemistry and clinical applications of malfunction of glucose metabolism are important. Glucose testing in a hospital setting can lead to important results such as if a patient has diabetes or hyperglycemia. This paper focuses on glucose testing done in a clinical setting and the biochemistry behind why and how glucose testing serves such an important role.

Biochemistry of Glucose and its metabolism: As it has already been established glucose is the primary source of energy, it is found in many tissues of the human body. For example, the nervous tissues itself cannot produce carbohydrates; due to this it is essential to have a steady supply of glucose to the tissue. Similarly, the liver and pancreas to perform its metabolism utilize glucose. Most of the ingested food is carbohydrates, which has to be broken down to glucose before it can be utilized by the body for it’s metabolic functions. Glucose once derived from the carbohydrates through enzymes such as…
