What is L-Threonine?

Threonine is one of the 20 most common natural amino acids. Threonine is another hydroxyl-containing amino acid. It differs from serine by having a methyl substituent in place of one of the hydrogens on the carbon and it differs from valine by replacement of a methyl substituent with a hydroxyl group.

The hydroxyl group is fairly reactive, being able to form hydrogen bonds with a variety of polar substrates. Threonine is an important component in the formation of protein, collagen, elastin and tooth enamel.

It is also important for production of neurotransmitters and health of the nervous system. Nutritionally, in humans, threonine is also an essential amino acid. Human beings cannot synthesize it from simpler metabolites. Threonine is must be obtained through the diet.

Threonine functions, uses, and health benefits:
Threonine is an important part of many proteins in the body and is necessary for the formation of tooth enamel and elastin and collagen which are needed for both healthy skin and wound healing.

Threonine has a mild glucose-sparing effect and is useful in the stabilization of blood sugar because it can be converted into glucose in the liver by the process of gluconeogenesis. Threonine is one of the immune-stimulating nutrients (cysteine, lysine, alanine, and aspartic acid are others), as it promotes thymus growth and activity.

Threonine may enhance immunity by assisting in the production of agents that fight viral infections. It also can probably promote cell immune defense function. Threonine is important in the formation of collagen and elastin.

When combined with aspartic acid, methionine aids liver and lipotropic function. Threonine is used to treat indigestion and intestinal malfunctions. Threonine may prevent fat from accumulating in the liver. A fatty liver can affect liver function and is associated with diseases of the liver such as cirrhosis. Threonine is an immunostimulant which promotes the growth of thymus gland.

Threonine is one of the amino detoxifers. It helps prevent fatty buildup in the liver. Threonine is important component of collagen. It is generally low in vegetarians. It is a precursor of isoleucine and imbalance may result if the synthesis rate from asparate is incorrect. In humans, deficiency may result in irritability and a generally difficult personality.

L-Threonine is commonly used to relieve stress and anxiety. Since it also aids in the production of neurotransmitters in the central nervous system, L-Threonine is crucial in maintaining not only a healthy physical lifestyle, but a healthy mental lifestyle as well.

Before taking or combining any supplement, it is important to consult with your physician to determine any health risks or side effects that may come with mixing supplements with other medications you may be taking.
