Is methylglyoxal toxic?

Introduction. Methylglyoxal (MG) is a toxic α-dicarbonyl compound derived from glucose, amino acids and acetone degradation pathways and detoxified by ubiquitous glyoxalase system (Kalapos, 1999. Methylglyoxal in living organisms: chemistry, biochemistry, toxicology and biological implications.

What contains methylglyoxal?

Methylglyoxal is present in many foods and drinks, including coffee, and is produced during glycolysis and sugar fermentation. It is produced by many strains of bacteria present in the intestinal tract. It is also present in tobacco smoke.

Does methylglyoxal cause cancer?

An inverse correlation exists between MGO concentrations and tumor progression. High MGO levels cause growth arrest in several types of cancer. Conversely, a lower increase in MGO concentrations can promote cancer growth.

Where can methylglyoxal be found?

Manuka honeys
In conclusion, methylglyoxal is a unique anti- bacterial compound found in high concentrations in Manuka honeys from New Zealand and directly responsible for the specific antibacterial activity of these samples.

Is methylglyoxal healthy?

Methylglyoxal is its active ingredient and likely responsible for these antibacterial effects. Additionally, manuka honey has antiviral, anti-inflammatory and antioxidant benefits. In fact, it has traditionally been used for wound healing, soothing sore throats, preventing tooth decay and improving digestive issues.

Why is methylglyoxal bad?

The accumulation of the cell-permeant MG is highly deleterious, since this compound is one of the most potent glycating agents produced in cells. It readily reacts with proteins, lipids and nucleic acids to form advanced glycation end products (AGEs).

How is methylglyoxal formed in the body?

Methylglyoxal is formed from dihydroxyacetone phosphate (DHAP) by the enzyme methylglyoxal synthase, giving off a phosphate group. If methylglyoxal enters the glyoxylase pathway, it is converted into lactoylguatathione and eventually D-lactate. Both D-lactate, and L-lactate are then converted into pyruvate.

Is Methylglyoxal healthy?

Is Methylglyoxal good for diabetes?

It is widely recognized that non-enzymatic glycation in diabetes is a major cause of damage and dysfunction of key vascular cells. MG (methylglyoxal) is directly toxic to tissues, and is a major precursor of AGEs (advanced glycation end-products).

Is honey OK for diabetes?

If your diabetes is well-controlled and you want to add honey to your diet, choose pure, organic, or raw natural honey. These types are safer for people with diabetes because all-natural honey doesn’t have any added sugar.
