BeschreibungMethionine is an α-amino acid with the chemical formula HO2CCH(NH2)CH2CH2SCH3. This essential amino acid is classified as nonpolar. This amino-acid is coded by the initiation codon AUG which indicates mRNA's coding region where translation into protein begins.
OccurrenceHigh levels of methionine can be found in eggs, sesame seeds, Brazil nuts, fish, meats and some other plant seeds; methionine is also found in cereal grains. Most fruits and vegetables contain very little of it. Most legumes are also low in methionine. Racemic methionine is sometimes added as an ingredient to pet foods.
VerwendenDL-Methionine is sometimes given as a supplement to dogs; it helps keep dogs from damaging grass by reducing the pH of the urine. Methionine is allowed as a supplement to organic poultry feed under the US certified organic program.
synthetischeDL-Methionine is prepared by addition of methanethiol to acrolein; by chemical conversion of methylthiopropionic aldehyde.
