Modified alpha-lactalbumin

摘要

Modified alpha -lactalbumin, for example of bovine or human origin, comprising fewer phenylalanine residues than wild type alpha -lactalbumin may be used as a dietary component for sufferers of hyperphenylalaninemia. Preferably all of the phenylalanine residues are replaced. The modified alpha -lactalbumin may be expressed in the mammary gland of non-human host animals so as to accumulate in, and if desired be separated from, their milk.
