Which Joe gave his name to ‘sloppy joes’? We look at five interesting sandwiches and their lexical origins.
[mass noun] A colourless volatile liquid aldehyde obtained by oxidizing ethanol.
- ‘Alcohol and acetaldehyde (the initial metabolite of ethanol) have been examined in experimental test systems.’
- ‘Ethanol is primarily metabolized to acetaldehyde by the action of alcohol dehydrogenase.’
- ‘Though the metabolism of acetaldehyde is of interest and importance in any discussion of ethanol detoxification, space limitations discourage such commentary.’
- ‘To investigate this point further, we first established the impact of oxygen deprivation, and also of a return to air, on the dynamics of fermentation by monitoring oxygen and the production of ethanol, acetaldehyde and carbon dioxide.’
- ‘The enzyme aldehyde dehydrogenase is responsible for efficient metabolism of alcohol after it has been oxidised to acetaldehyde.’
- ‘The predominant emissions from uncoated wood and wood-based materials were aldehydes, mainly acetaldehyde, propanal, butanal, pentanal, hexanal, and acetone.’
- ‘The validity of this assay may be questioned since acetaldehyde is a highly volatile and reactive molecule.’
- ‘The first enzyme converts alcohol into a very toxic substance called acetaldehyde.’
- ‘Over 90% of the variation in flavor scores could be explained by changes in ethanol and acetaldehyde content.’
- ‘Number one is the build up of toxins such as acetaldehyde and free radicals, as your liver struggles to cope with metabolizing large amounts of alcohol.’
- ‘The fumes also contain sulfur dioxide, and various aldehydes, primarily formaldehyde as well as acetaldehyde and acrolein.’
- ‘The chemicals that most often exceeded limits were naphthalene, formaldehyde and acetaldehyde.’
- ‘A second dehydrogenation turns acetaldehyde into acetic acid, aka vinegar, which gets digested as usual.’
- ‘Meanwhile, as the liver metabolises alcohol it produces acetaldehyde, a vinegar-like substance which has a toxic effects on the liver itself, the brain and the stomach lining, causing severe headaches.’
- ‘It occurs synthetically as a byproduct in the manufacture of acetaldehyde and formaldehyde and during the atmospheric oxidation of turpentine.’
- ‘Another contributory factor is the conversion of alcohol to acetaldehyde by the liver.’
- ‘An enzyme in the liver called alcohol dehydrogenase strips electrons from ethanol to form acetaldehyde.’
- ‘Mucous membrane irritation occurs at considerably higher concentrations for acetaldehyde than for formaldehyde, and the risk of cancer has been investigated less vigorously.’
- ‘The jury is still out on whether Hangovers are caused by too much acetaldehyde in the blood stream, or by leaching by Alcohol of essential vitamins, minerals, and water, or by any number of other causes.’
- ‘Most researchers believe that hangovers are created by build ups of acetaldehyde, although others shift the blame from ethanol and its side products to methanol.’
