Methionine hydroxy analog

Methylmercaptopropionaldehyde is also used to make the methionine hydroxy analog CH2SCH2CH2CH(OH)COOH [583-91 -5] which is used commercially as an effective source of methionine activity (71). AH commercial syntheses of methionine and methionine hydroxy analog are based on the use of acrolein as a raw material. More than 170,000 tons of this amino acid are produced yearly (30) (see Amino acids). One method for the preparation of methionine from acrolein via 3-methyhnercaptopropionaldehyde is as follows.

The hydroxy- and sulfur-containing amino acids are generally more hydrophilic than their aliphatic analogs, although methionine is fairly hydrophobic. 

The hydroxy and sulfur-containing amino acids are generally more hydrophilic than their aliphatic analogs, although methionine is fairly hydrophobic. Cysteine can ionize at high pH (see here) Cysteine, together with another cysteine in a protein, can form disulfide bonds (see here). Disulfide bonds help to stabilize the structure of some proteins.
