2. N-Acetyl-L-Tyrosine is an acetylated derivative of the essential amino acid L-tyrosine.
Ordinary L-tyrosine is less stable and insoluble in water, which may result in reduced bioavailability.
3. N-acetyl-L-tyrosine, which is converted in the body to L-tyrosine, is 20 times as soluble in water as L-tyrosine itself. For this reason, it serves as an efficient supplement for raising tyrosine levels in the body, since undissolved substances are not absorbed from the digestive tract.
4. N-acetyl-L-Tyrosine enhances the solubility and stability making it a more rapidly absorbed and bioavailable form of the amino acid L-tyrosine which is less prone to urinary excretion.
(1) N-Acetyl-L-Tyrosine can be Medicine used as thyrotoxicosis;
(2) N-Acetyl-L-Tyrosine can be used as food additives.
(3) N-Acetyl-L-Tyrosine is a kind of important biochemical reagent, synthesis peptide hormones, antibiotics, L - dopamine drugs such as the main raw material.
(4) N-Acetyl-L-Tyrosine is Widely used in agricultural science research, and drink additive and compound artificial insects feed.
