tyrosine
L-Tyrosine is a neutral, genetically coded, semi-essential amino acid (meaning that the human body can produce it on its own with proper nutrition). It is marginally soluble in water.
When referring to amino acids, the words essential and non-essential dont have their normal meanings. Essential amino acids are amino acids that the human body can not produce on its own and must gather from food sources. Non-essential amino acids are amino acids that the human body can produce on its own. Both kinds are required for human health.
