What kind of research results did experts get on feed grade L-Threonine?
Threonine was discovered in fibrin hydrolysate in 1935. The first studies on threonine requirements were published in the 1960s and early 1970s. However, it was not until the 1980s that people had a breakthrough in the understanding of whose nutritional value, and a series of derivatives such as L-Threonine crystal were born.
What place does L-Threonine stand in structure of animal husbandry?
In the actual production of animal husbandry, due to the lack of feed grade L-Threonine in ordinary feed, it is necessary to increase the protein level of the feed to meet the needs of livestock for L-Threonine crystal, resulting in excessive amounts of other elements.
Threonine
Twenty amino acids form the building blocks for protein, enzymes, genetic material, and hormones in the human body. The amino acids are divided into two groups- essential amino acids and non-essential amino acids. Essential amino acids are not synthesized by our bodies and need to be acquired from our diets.
Amino Acid Functional Group
All amino acids are comprised of a central carbon surrounded by a carboxyl group, an amino group, and an R group. It is this R group which determines the properties of an amino acid, such as its charge, polarity, and aromaticity. The identity of an amino acid is determined by its R group.
Threonine Structure
The molecular formula for threonine is C4H9NO3. It is a linear molecule that is polar in nature due to its R group, which contains a side chain with a hydroxyl group. Aside from this R group, threonine contains the other basic components of an amino acid, such as a carboxyl group, an amino group, and a hydrogen about a central carbon.
Threonine Benefits

Threonine is often administered as a supplement for people suffering from nervous system disorders associated with multiple sclerosis and amyotrophic lateral sclerosis (Lou Gehrig's disease).
What is the amino acid threonine?
Threonine is an essential amino acid that plays an important role in regulating protein balance in the body. Because it’s considered an “essential amino acid,” that means the body doesn’t synthesize the amino acid, so we need to eat foods high in threonine to obtain it. The threonine abbreviation is Thr, and its one letter code is T.
