Diminished alcohol preference in transgenic mice lacking aldehyde dehydrogenase activity. Butanal amounts and total aldehydes evolved, on the other hand, showed a high negative correlation with peroxide amounts. The three most active compounds were 6-carbon aldehydes and alcohols, components of general green leaf volatiles. In other words, it was not possible to conclude that aldehyde had a higher affinity for oxygen. The slide was immersed in an aldehyde-dichromate mixture, and then in 1% silver nitrate, for a few days each. Rat brains were then aldehyde-fixed and processed using standard methods. The remaining hydrocarbons, terpenoids and aldehydes were found in both categories of seeds in similar quantities. Consequently, the presence of aldehydes and ketones found in meteorites cannot be considered as proof that they are precursors of amino acids. The latter compounds are typical by-products of bacterial metabolism and include aldehydes, esters, ketones and short-chain alcohols. Of the 13 compounds that were identified, six were aldehydes. It is possible these monocarboxylic acids and aldehydes present in liquid smoke work together to break dormancy. They catalyse the oxidative deamination of primary amines by dioxygen to form aldehydes, ammonia, and hydrogen peroxide. These studies used classical descriptive electron microscopy after aldehyde-osmium fixation, excluding the application of most of the fine-structural cyto- and immunocytochemical assays. These compounds probably arise from a reaction with 4-hydroxy-2-nonenal, the main aldehyde compound released during lipid peroxidation, or after occupational exposure to vinyl chloride. Alternatively, acetylene may yield amino acids directly via a conversion of an alkyne to the corresponding aldehyde, which then forms an alpha amino nitrile and eventually an amino acid. They were then mounted in a sandwich of filter paper, which was held flat by a coverslip and rubber bands on a glass slide and were then fixed in aldehydes. That process has the advantage of getting rid of the aldehydes which are the injurious elements in raw whisky. From the Hansard archive Example from the Hansard archive.

The aldehyde is oriented such that the hydrogen is placed in a pseudo-axial orientation to minimize 1,3-diaxial interactions.
