Dictionary » A » Aldehyde



(Science: chemistry) a carbon atom double-bonded to an oxygen, single-bonded to a hydrogen, and single-bonded to another chemical group (such as methane, benzene, another hydrogen, anything).

The carbon oxygen double bond part is known as a carbonyl group (C=O). An example is acetaldehyde, which is a carbonyl group single-bonded to a hydrogen and single-bonded to a methane (a methyl group: CH3).

Re: Relationship between structure and function of glucoes

... form (though one molecule, at one instant, if bound in a ring, will be in either α or β form). As a monomer, glucose is in equilibrium with a free aldehyde form. When the aldehyde reacts intramolecularly to form a closed ring, the resulting ring will be in α or β form depending on which face the ...

Re: the Calvin cycle???help please

... knowledge, no one has done a calculation on which of the above-described pathways is more probable. [The reduction is from an acid carbonyl to an aldehyde carbonyl, a difficult, many-body problem, I think.] If I were to guess, I'd go for the "hydrogen tunneling" rather than the two-step ...

'asian flush syndrom' and methanol intoxication

so with asian flush syndrome they have underactive aldehyde dehydrogenase right? and so methanol is converted to formaldehyde and this is toxic when it builds up... therefore people with asian flush syndrome would be more susceptible than someone ...

Four Questions on Cellular Respiration

... the fate of alcohol, but I just remember that in the yeast it is transported out of the cell and in humans alcohol dehydrogenase convert it to the aldehyde. So alcohol is like a waste. Am I right, Andrew? ;)
