Before revision: l-Photo-Leucine and l-Photo-Methionine are analogs of the naturally occurring l-Leucine and l-Methionine amino acids that are endogenously incorporated into the primary sequence of proteins during synthesis using the normal translation machinery.
After revision: L-Photo-Leucine and L-Photo-Methionine are analogs of the naturally occurring L-Leucine and L-Methionine amino acids that are endogenously incorporated into the primary sequence of proteins during synthesis using the normal translation machinery.
