Question

Lanthionine is a nonstandard amino acid consisting of two alanine residues linked via their β carbon atoms by a thioether (—S—) linkage. Draw the structure of lanthionine.

Short answer

The detailed structural composition of the lanthionine was understood.

Step-by-step solution

What is non stranded amino acid?

After their incorporation into the protein, the posttranslational modifications of the amino acids are called non-stranded amino acids.

Structure of the Lanthionine

Hence, it was understood that lanthionine is a dipeptide of Alanine residues formed by the thioether linkage of β carbon atoms.
