Red-leaf lettuce owes its vibrant color to anthocyanins, a type of polyphenolic pigment that has garnered attention for its antioxidant properties.
Research indicates that these pigments are produced through specific enzymatic reactions that begin with the amino acid phenylalanine.
The findings suggest that a tiny gene switch can significantly impact the chemical makeup of red lettuce, potentially revealing tradeoffs in its nutritional profile.
