Acrylamide (or acrylic amide) is an organic compound with the chemical formula CH 2 =CHC(O)NH 2.It is a white odorless solid, soluble in water and several organic solvents. From the chemistry perspective, acrylamide is a vinyl-substituted primary amide (CONH 2).
Roast pork, browned using the Maillard reaction The preparation of French fries at high temperature can lead to the formation of acrylamide. [6] The browning reactions that occur when meat is roasted or seared are complex and occur mostly by Maillard browning [11] with contributions from other chemical reactions, including the breakdown of the ...
The polymerization reaction creates a gel because of the added bisacrylamide, which can form cross-links between two acrylamide molecules. The ratio of bisacrylamide to acrylamide can be varied for special purposes, but is generally about 1 part in 35. The acrylamide concentration of the gel can also be varied, generally in the range from 5% to ...
Polyacrylamide is of low toxicity but its precursor acrylamide is a neurotoxin and carcinogen. [1] Thus, concerns naturally center on the possibility that polyacrylamide is contaminated with acrylamide. [12] [13] Considerable effort is made to scavenge traces of acrylamide from the polymer intended for use near food. [1]
The reaction proceeds via N-hydroxymethylacrylamide, which can be detected in alkaline solution and decomposes in acid to give N,N′-methylenebisacrylamide. Using acrylamide and paraformaldehyde in 1,2-dichloroethane gives a clear solution upon heating, from which MBA crystallizes.
Proteins of the erythrocyte membrane separated by SDS-PAGE according to their molecular masses. SDS-PAGE (sodium dodecyl sulfate–polyacrylamide gel electrophoresis) is a discontinuous electrophoretic system developed by Ulrich K. Laemmli which is commonly used as a method to separate proteins with molecular masses between 5 and 250 kDa.

The carboxyl group of acrylic acid can react with ammonia to form acrylamide, or with an alcohol to form an acrylate ester. Acrylamide and methyl acrylate are commercially important examples of α,β-unsaturated amides and α,β-unsaturated esters, respectively. They also polymerize readily.
