The
Characteristics and Uses：
|
L-phenylalanine
is a bioactive aromatic amino acid. It is a necessary amino acid which
cannot be self-synthesized by human and animals. It is necessary for
a person to intake 2.2g L-phenylalanine every day. As one of the
eight necessary amino acids for human body, it has been widely used
in pharmaceutical and food additive industry. It is an important ingredient
of amino acid injection. In food processing industry, L-phenylalanine
can be added into bakery foods. And the nutrition of phenylalanine
can be enhanced and by amido-carboxylation with glucide.
L-phenylalanine
can enhance foods aroma and keep the balance of necessary amino acids.
In pharmaceutical industry, L-phenylalanine is used as intermediate
of some amino anticancer pharmaceuticals such as formylmerphalanum
and etc. It is also used to manufacture adrenalin, thyroxin and melanin.
Another important application is to synthesize aspartame with L-aspartic
acid.
