ISO Certified Amino Acid L-Lysine Hydrochloride/ L-Lysine HCL CAS 657-27-2

ISO Certified Amino Acid L-Lysine Hydrochloride/ L-Lysine HCL CAS 657-27-2

Traditional/Ethnobotanical uses

Lysine is an essential amino acid in human nutrition because the body cannot produce it; therefore, it must be taken in either by diet

or supplementation. Lysine was first isolated from casein (a milk phosphoprotein) in 1889. It was first introduced in the United States

as lysine hydrochloride in 1955. There was an interest in fortifying bread with lysine to target populations with lysine-poor diets. However,

the FDA refused to modify the standards of identity for white bread. Since 1970, lysine has been commonly added to animal feed.

General uses

Lysine has been studied for the prevention and treatment of herpes infections and cold sores. It also increases the intestinal absorption

of calcium and eliminates its excretion by the kidney, suggesting that it might be helpful in osteoporosis. Lysine has been investigated for

its effects on increasing muscle mass, lowering glucose, and improving anxiety. Case reports suggest lysine may ameliorate angina. Lysine

acetylsalicylate has been used to treat pain. Lysine clonixinate has been used to treat migraine

headaches and other painful conditions. However, limited clinical trials exist for these conditions.

An essential amino acid found in corns and legumes. It plays an important role in protein metabolism and is vital for growth of infants.

Leucine may also promote muscle growth during recovery after prolonged exercise or after hard training sessions. It is one of the

branch-chained amino acids, which can be used by muscles as an energy source.

Function & Application

1. Cysteine hydrochloride monohydrate is soluble in water, and can be quickly absorbed by the human body as an injection

or tablet. It is the main raw material for the production of carboxymethylcysteine and acetylcysteine;

2. Cysteine hydrochloride monohydrate used in Bread improver; nutritional supplement, antioxidant, color protection agent.

It has detoxification effect on acrylonitrile and aromatic poisoning, has the effect of preventing radiation damage, and has

the treatment of bronchitis and phlegm.

Tyrosine is an amino acid. Amino acids are the building blocks of protein. The body makes tyrosine from another amino acid

called phenylalanine. Tyrosine can also be found in dairy products, meats, fish, eggs, nuts, beans, oats, and wheat.


Tyrosine is most commonly used in protein supplements to treat an inherited disorder called phenylketonuria (PKU). People

who have this disorder can't process phenylalanine properly. As a result they can't make tyrosine. To meet their bodies' needs,

supplemental tyrosine is given.

How does it work

The body uses tyrosine to make chemical messengers that are involved in conditions involving the brain such as mental alertness.

1. N-Acetyl-L-Tyrosine is a highly bioavailable form of L-tyrosine for the natural precursor treatment of low moods
N-acetyl-L-tyrosine can be used in lower doses than L-tyrosine.

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.
