Its use as a food dye was legalized in the US by the Pure Food and Drug Act of 1906. [6] By early 1920s, it was produced mainly for the food industry, [ 7 ] with 2,170 pounds (0.98 t) made in America in 1924, [ 8 ] rising to 9,468 pounds (4.29 t) in 1938 [ 9 ] and approximately 50 tons in 1967.
In the food industry, tyrosinase inhibition is desired as tyrosinase catalyzes the oxidation of phenolic compounds found in fruits and vegetables into quinones, which gives an undesirable taste and color and also decreases the availability of certain essential amino acids as well as the digestibility of the products.
A mutation may occur to replace a tyrosine (which needs to be phosphorylated in order to activate the protein) with an aspartic acid (which would not need to be phosphorylated). In a laboratory setting, the use of recombinant proteins to artificially introduce phosphomimetics is a common tool for studying phosphorylation and protein activation.
The diet was originally based on the elimination of salicylate, artificial food coloring, and artificial flavors; [4] later on in the 1970s, the preservatives BHA, BHT, [5] and (somewhat later) TBHQ [6] were eliminated. Besides foods with the eliminated additives, aspirin- or additive-containing drugs and toiletries were to be avoided.
Dityrosine is a dimeric form of tyrosine.Whereas tyrosine itself is a proteinogenic amino acid, dityrosine is non-proteinogenic.Various enzymes, such as CYP56A1 and myeloperoxidase, catalyze the oxidation of tyrosine residues in protein chains to form dityrosine crosslinks in various organisms.
