LAA	Lys	Lys	Lys

Aromatic amino acid (phenylalanine + tyrosine). Sulfur-containing amino acid (methionine + cysteine). Limiting amino acid. SPI = sesame protein isolates, FPI = flaxseed protein isolates, and CPI = canola protein isolates. The values for Lysine have been presented in bold to indicate that it is the Limiting Amino Acid.
