Definition: Delphinoidine is a type of amino acid that has been identified as playing an important role in cellular function, particularly in the development and differentiation of neurons. It's found in the brain and spinal cord, where it plays a crucial role in synaptic plasticity, which is the ability of a neuron to change its electrical activity over time. Delphinoidine can be synthesized by the action of enzymes like Ξ±-tocopherol (vitamin E) or Ξ±-tocamylase,
