Methylglyoxal is a simple organic compound that is a byproduct of various metabolic processes in living organisms. It is a colorless liquid with a sweet odor and is known for its role in the formation of advanced glycation end products (AGEs), which can contribute to cellular damage and aging. In addition to its natural occurrence, methylglyoxal is also found in certain foods, such as honey and coffee. It has gained attention for its potential antibacterial properties, particularly in relation to Manuka honey, which is known for its high methylglyoxal content and associated health benefits.
