In biochemistry, denaturation is a process in which proteins or nucleic acids lose folded structure present in their native state due to various factors, including application of some external stress or compound, such as a strong acid or base, a concentrated inorganic salt, an organic solvent (e.g., alcohol or chloroform), agitation and radiation, or heat.

Alcohol dehydrogenase activity varies between men and women, between young and old, and among populations from different areas of the world. For example, young women are unable to process alcohol at the same rate as young men because they do not express the alcohol dehydrogenase as highly, although the inverse is true among the middle-aged. [37]
Some enzymes do not need additional components to show full activity. Others require non-protein molecules called cofactors to be bound for activity. [58] Cofactors can be either inorganic (e.g., metal ions and iron–sulfur clusters) or organic compounds (e.g., flavin and heme).
Enzymes all have specific purposes and capabilities. Time to learn about them.
Understanding the distinctions between alcohol intolerance and alcohol allergy is crucial for proper alleviation of symptoms. Alcohol intolerance results from metabolic challenges related to enzyme function, while alcohol allergy involves the immune response. Recognizing these differences can help individuals avoid triggers and seek appropriate ...
Direct alcohol tolerance is largely dependent on body size. Large-bodied people will require more alcohol to reach insobriety than lightly built people. [4] The alcohol tolerance is also connected with activity of alcohol dehydrogenases (a group of enzymes responsible for the breakdown of alcohol) in the liver, and in the bloodstream.
Disulfiram is a medication used to support the treatment of chronic alcoholism by producing an acute sensitivity to ethanol (drinking alcohol). Disulfiram works by inhibiting the enzyme aldehyde dehydrogenase (specifically the ALDH2 enzyme [3]), causing many of the effects of a hangover to be felt immediately following alcohol consumption.
The reinforcing effects of alcohol consumption are mediated by acetaldehyde generated by catalase and other oxidizing enzymes such as cytochrome P-4502E1 in the brain. [60] Although acetaldehyde has been associated with some of the adverse and toxic effects of ethanol, it appears to play a central role in the activation of the mesolimbic ...
