General description
Together with the companion product Phospho-L-Tyrosine disodium Salt disodium salt, the new modified amino acid S-Sulfocysteine sodium salt can be used as replacement for cysteine to generate highly concentrated, neutral pH feeds. Both modified amino acids eliminate the need for alkaline feeds, which are normally applied to ensure solubility and stability of the unmodified amino acids tyrosine and cysteine.
