l-threonine with the CAS number 6028 - 28 - 0 is an essential amino acid. It is an optically active form of threonine having L-configuration. The molecular formula of l-threonine is C₄H₉NO₃, and its molecular weight is approximately 119.12 g/mol. It appears as a white crystalline powder, odorless, and has a slightly sweet taste. This amino acid is highly soluble in water, with a solubility of about 108 g/L at 25°C, while it is insoluble in ethanol and ether.
Our Factory Supply l-threonine is produced under strict quality control standards, ensuring high purity, usually above 98%. This high - purity product can meet various industrial and research requirements. It is available in different packaging sizes to suit different customer needs, from small - scale laboratory use to large - scale industrial applications.
In the field of animal nutrition, l-threonine is widely used as an additive in animal feed. It is an essential amino acid for animals, which cannot be synthesized in sufficient amounts by their bodies. By adding l-threonine to feed, it can improve the quality of the feed protein, enhance the growth performance of animals, such as increasing the daily weight gain of pigs and poultry, and improving the egg - laying rate of chickens. It also helps to reduce the amount of nitrogen excretion in animals, which is beneficial for environmental protection.
In the human nutrition industry, l-threonine can be used as a nutritional supplement. It plays an important role in maintaining the normal physiological functions of the human body, such as promoting the synthesis of immunoglobulins, enhancing the immune system, and supporting the normal growth and development of children. Moreover, it is often used in the formulation of special medical foods for patients with certain diseases or nutritional deficiencies.
In the pharmaceutical industry, l-threonine can be used as a raw material for the synthesis of some drugs. It can participate in the synthesis of peptide drugs and some antibiotics, and may also have potential applications in the development of new drugs due to its unique chemical structure and biological activity.
For Animal Feed: The recommended dosage of l-threonine in animal feed depends on the type of animals, their age, and growth stage. For example, in piglet feed, the addition amount of l-threonine can be around 0.2% - 0.4%. In poultry feed, for broilers, the addition amount may range from 0.3% - 0.5%. It is usually evenly mixed with other feed ingredients during the feed production process to ensure uniform distribution in the final feed product.
As a Human Nutritional Supplement: When used as a nutritional supplement for humans, the dosage should be determined according to individual needs and health conditions. It is generally recommended to consult a doctor or a professional nutritionist. Usually, it can be taken orally with water, and it is better to take it before or after a meal to improve absorption.
In Pharmaceutical Synthesis: In the pharmaceutical industry, the use of l-threonine needs to follow strict chemical synthesis procedures. It should be used in a well - equipped laboratory or production environment, and the reaction conditions such as temperature, pressure, and reaction time need to be precisely controlled according to the specific synthesis process.
Case 1: Pig Farming
A pig farm in a certain area added our l-threonine to the piglet feed. Before using l-threonine, the average daily weight gain of piglets was about 250 grams. After adding 0.3% l-threonine to the feed for two months, the average daily weight gain increased to about 320 grams, an increase of about 28%. At the same time, the mortality rate of piglets also decreased from 5% to 2%, indicating that l-threonine can effectively improve the growth performance and health status of piglets.
Case 2: Poultry Farming
A chicken farm added l-threonine to the layer feed at a dosage of 0.4%. Before the addition, the average egg - laying rate of chickens was about 70%. After three months of using the feed with l-threonine, the egg - laying rate increased to about 80%. The eggshell quality also improved, with a lower breakage rate, which shows that l-threonine can enhance the productivity and egg quality of laying hens.
