l-tyrosine usage and synthesis |
chemical properties | white to off-white powder |
usage | neuromuscular blocker |
usage | l-tyrosine is one of the 22 proteinogenic amino acids that are used by cells to synthesize proteins. l-tyrosine is biologically converted from l-phenylalanine and is in turn is converted to l-dopa and further converted into the neurotransmitters: dopamine, norepinephrine, and epinephrine. |
