Secratatropin contains so many natural substances, including L-Tyrosine.
Tyrosine (abbreviated as Tyr or Y)[1] or 4-hydroxyphenylalanine, is one of the 22 amino acids that are used by cells to synthesize proteins.
The word "tyrosine" is from the Greek tyri, meaning cheese, as it was first discovered in 1846 by German chemist Justus von Liebig in the protein casein from cheese. It is called tyrosyl when referred to as a functional group or side chain.
It plays an important role in the production of neurotransmitters that regulate emotions. The body makes l-tyrosine from another amino acid, known as phenylalanine.
