Usage
White crystalline powder
White, crystalline platelets or powder having a characteristic odor. One g dissolves in about 30 mL of water. It is soluble in dilute acids and in solutions of alkali hydroxides. It is very slightly soluble in alcohol, and practically insoluble in ether. It is optically inactive. The pH of a 1 in 100 solution is between 5.6 and 6.1. This substance may be prepared by addition of methanethiol to acrolein; by chemical conversion of methylthiopropionic aldehyde.
d,l-Methionine has a characteristic odor. It is an essential amino acid and is also used as a nutrient and dietary supplement.
Production of volatile compounds related to the flavour of foods from the Strecker degradation of DL-methionine. Addition of methionine in appropriate amounts to these foods might be expected to improve protein value. Economically, DL-methionine would be preferable. An essential nonpolar amino acid with oxidative stress defense properties.DL-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.
