What's the difference between acetaldehyde and ethanal?
Acetaldehyde
Definition:
(n.) Acetic aldehyde. See Aldehyde.
Example Sentences:

(5) Acetaldehyde was found to be transported in the blood mainly bound reversibly to 2 components of the red blood cells (RBC): a) hemoglobin, which provides binding of a high affinity, but low capacity, and b) a non-protein component (presumably cysteine), which has a lower affinity but a higher capacity.

(11) Both alcohol oxidation and acetaldehyde reduction follow a compulsory ordered pathway, with coenzyme binding first.
