Carl Sagan

A sharp distinction between humans and “animals” is essential if we are to bend them to our will, make them work for us, wear them, eat them–without any disquieting tinges of guilt or regret. It is unseemly of us, who often behave so unfeeling toward other animals, to contend that only humans can suffer. The behavior of other animals renders such pretensions specious. They are just too much like us.

Phenylalanine

Phenylalanine is an essential amino acid.

Provided by diet, phenylalanine can be converted into another amino acid, tyrosine, in the body. Tyrosine is used to synthesize two key neurotransmitters that promote alertness: dopamine and norepinephrine. 

It has 3 forms:

  • D-phenylalanine;
  • L-phenylalanine - most common, the form in which phenylalanine is incorporated into the body’s proteins;
  • DL-phenylalanine.
