A glucose-centric perspective of hyperglycemia
Indian Journal of Experimental Biology
|March 4, 2016
Summary
Maintaining ideal blood glucose levels is crucial for health. Insulin regulates glucose uptake and storage, but impaired insulin function and lifestyle changes lead to hyperglycemia and glycation damage.
Area of Science:
- Biochemistry and Physiology
- Metabolic Regulation
- Endocrinology
Background:
- Dietary carbohydrates like starch and glycogen are converted to glucose, which enters the bloodstream.
- Maintaining blood glucose concentration within 80-120 mg/100 mL is vital, facilitated by glucose transporters (GLUTs).
- Excess glucose is stored as glycogen in the liver and muscles, with insulin signaling key regulatory pathways.
Purpose of the Study:
- To explore the mechanisms of glucose regulation and the consequences of its dysregulation.
- To review factors contributing to increased incidence of blood glucose control failure and insulin resistance.
- To examine therapeutic strategies and compounds for managing blood glucose levels.
Main Methods:
- Review of biochemical pathways involved in glucose metabolism, insulin signaling, and glycation.
- Analysis of factors influencing insulin resistance and glycogen storage dysfunction.
- Evaluation of various compounds and strategies for blood glucose management, including herbal products and artificial sweeteners.
Main Results:
- High blood glucose triggers insulin release, activating signaling cascades for glycogen and triglyceride synthesis, while inhibiting hepatic glucose production.
- Insulin resistance, often linked to lifestyle changes, leads to prolonged hyperglycemia and detrimental protein glycation.
- Some compounds like vanadium-peroxide complexes and fungus derivatives show insulin-mimicking activity, while herbal products and Metformin offer therapeutic benefits.
Conclusions:
- Effective blood glucose control requires addressing defects in glucose uptake into glycogen stores, a challenge for current drugs and diets.
- Understanding insulin resistance and glycation is critical for preventing long-term complications affecting organs like the heart, kidneys, eyes, and nerves.
- While artificial sweeteners and some compounds show promise, their long-term effects and ideal application in glucose management require further investigation.

1.3K
Without prolonged fasting, healthy individuals maintain blood glucose levels above 3.5 mM due to a well-adapted neuroendocrine counterregulatory system that effectively prevents acute hypoglycemia, a potentially life-threatening condition. The primary clinical scenarios for hypoglycemia encompass diabetes treatment, inappropriate production of endogenous insulin or insulin-like substances by tumors, and the use of glucose-lowering agents in non-diabetic individuals. Notably, hypoglycemia in the...

Carbohydrates consumed through foods are converted into glucose, a crucial energy source for the body. In the prandial state, high blood glucose levels stimulate the secretion of insulin from the pancreas. Insulin inhibits hepatic glucose production and stimulates glucose uptake and metabolism by muscle and adipose tissue. The excess glucose is converted into glycogen and stored in the liver and muscles.

Carbohydrate metabolism is a fundamental biochemical process that ensures a constant supply of energy to living cells. The most important carbohydrate is glucose, which can be broken down via glycolysis to enter into the Krebs cycle and eventually lead to the production of ATP through oxidative phosphorylation.

The pancreatic islets comprising only 1%-2% of the volume are highly vascularized and innervated mini-organs. They contain five endocrine cell types, including β cells that secrete insulin, which is synthesized as a single polypeptide chain, preproinsulin, processed to proinsulin, and finally to insulin and C-peptide. This process is complex and regulated, involving the Golgi complex, the endoplasmic reticulum, and the secretory granules of the β cell.

For most patients, experiencing several weeks of polyuria, polydipsia, fatigue, and significant weight loss may indicate the presence of diabetes. Furthermore, adults displaying the phenotypic appearance of type 2 diabetes (particularly those who are obese and not initially insulin-requiring), may have islet cell autoantibodies, suggesting autoimmune-mediated β cell destruction and a diagnosis of latent autoimmune diabetes of adults (LADA). The categorization of glucose homeostasis is...

8.3K
Insulin is released by beta cells of the pancreas when blood glucose levels are high. It facilitates glucose absorption and utilization in insulin-dependent cells with insulin receptors on their plasma membranes. Insulin promotes glucose uptake by increasing the number of glucose transport proteins in the cell membrane, allowing glucose to enter the cell. As a result, glucose utilization and ATP production are enhanced.
