Acetaldehyde Acetaldehyde Acetaldehyde

Acetaldehyde may be the injurious agent in acute alcoholic liver disease. It has been suggested that the mechanism of liver injury in this situation may be immunologically mediated. In the present study acetaldehyde has been bound to human liver plasma membranes. The activation of C3 by the acetaldehyde/membrane product was measured by immunofixation of the separated C3 components. Activation o...

Autodetachment spectroscopy of vibrationally excited acetaldehyde enolate anion, CH2CHO-

The autodetachment spectrum of acetaldehyde enolate anion, CH,CHO-, is recorded near 14180 cm-’ using a coaxial laserion threshold photodetachment spectrometer. The spectrum represents transitions from u= 1 in the v) C-C-O bending mode of CH,CHOto u=O m the autodetaching dipole-bound state of the anion. The 32 rotationally resolved (0, 1) hot band transitions reported here were fit to Watson’s ...

Enzymatic Conversion of Indole Acetaldehyde and Naphthalene Acetaldehyde to Auxins.

A neutral substance, convertible to an acid auxin, is present in various plant extracts (5, 9) and chemical preparations (9). As indicated by a number of biological tests, the neutral substance is in all likelihood 3-indole acetaldehyde and will for convenience be designated by this name in the present paper. In a previous paper (11) it was shown that 3-indole acetaldehyde is rapidly converted ...

Purity Determination of Acetaldehyde in an Acetaldehyde Certified Reference Material.

Acetaldehyde is regulated as a toxic substance in various fields, and the method for monitoring or analysis of acetaldehyde is important. However, handling is difficult because of the high reactivity and low boiling point of acetaldehyde. Therefore, a reference material for high purity acetaldehyde with high accuracy was not available. Although the measuring method of acetaldehyde as a reagent ...
