Definitions
from The American Heritage® Dictionary of the English Language, 5th Edition.
- noun Any of a class of highly reactive organic chemical compounds obtained by oxidation of primary alcohols, characterized by the common group CHO, and used in the manufacture of resins, dyes, and organic acids.
from The Century Dictionary.
- noun A transparent colorless liquid, CH3COH, of pungent suffocating odor, produced by the oxidation of ordinary alcohol.
- noun The general name of a class of compounds intermediate between alcohols and acids, derived from their corresponding primary alcohols by the oxidation and removal of two atoms of hydrogen, and converted into acids by the addition of an atom of oxygen.

- noun (Chem.) A colorless, mobile, and very volatile liquid obtained from alcohol by certain processes of oxidation.
- noun (Chem.) Any compound having the group -CHO. Methyl aldehyde, the simplest aldehyde, is more commonly called formaldehyde, H-CHO, and acetic aldehyde is now more commonly called
acetaldehyde . The higher aldehydes may be solids. A reducing sugar typically contains the aldehyde group. - noun (Chem.) a compound formed by the union of aldehyde with ammonia.

ALD-201 is a population of stem cells (ALDH (br) cells) produced using Aldagen's proprietary technology, which express high levels of an enzyme known as aldehyde dehydrogenase, or ALDH, and exhibit a variety of activities, that Aldagen believes may promote the regeneration of multiple types of cells and tissues.

During the reaction, large quantities of volatile oxidation products of alcohol, such as aldehyde, ethylic nitrate, &c., are evolved from the boiling liquid, whilst others, such as glycollic acid, remain in solution.
