Salicylic acid is biosynthesized from the amino acid phenylalanine.

The mutant protein has the amino acid phenylalanine at position 180 instead of valine.

In approximately half of cases, a phenylalanine loading test can be used to show decreased conversion from the amino acid phenylalanine to tyrosine.

It is biosynthesized from the amino acid phenylalanine by enzymatic decarboxylation.

Both mechanisms use cinnamic acid as their starting point, which is derived from the amino acid phenylalanine.

The starting material for production of monolignols is the amino acid phenylalanine.

Both are thio hydantoin derivatives of the amino acid phenylalanine.
