L-isoleucine Raw Material Manufacturer, basic introduction

L-isoleucine is an essential amino acid that plays important physiological functions in living organisms. The following provides a detailed introduction from aspects such as basic information, physical and chemical properties, sources, physiological functions, and application fields:

I. Basic Information

The chemical name of L-isoleucine is α-amino-β-methylvaleric acid. It is an α-amino acid containing 6 carbon atoms, with the molecular formula C6H13NO2. Its structure contains an amino group (-NH₂), a carboxyl group (-COOH), and a side chain with a methyl branch, and it belongs to hydrophobic amino acids.

II. Physical and Chemical Properties

Appearance: It appears as white crystalline flakes or a crystalline powder and is stable under normal temperature and pressure.

Odor: Odorless with a slightly bitter taste.

Solubility: Slightly soluble in water, insoluble in ethanol and ether, but soluble in dilute hydrochloric acid and alkaline solutions.

Isoelectric Point: The isoelectric point is 5.98.

III. Sources

Food Sources: It is widely present in foods. Foods rich in L-isoleucine include meats, fish, poultry, legumes, nuts, grains, etc. For example, every 100 grams of chicken breast contains approximately 1.2 grams of L-isoleucine; every 100 grams of soybeans contains approximately 1.25 grams of L-isoleucine.

Industrial Production: Industrially, it is mainly produced by the microbial fermentation method. Genetic engineering technology is used to construct engineering strains with high yield of L-isoleucine. Using starch hydrolysate sugars, molasses, etc. as raw materials, fermentation culture is carried out, and then through steps such as separation and purification, L-isoleucine products are obtained.

IV. Physiological Functions

Participation in Protein Synthesis: As one of the basic building blocks of protein synthesis, L-isoleucine participates in the synthesis of various proteins in the body, which is crucial for maintaining normal growth, development, and tissue repair of the body.

Regulation of Energy Metabolism: L-isoleucine can participate in the energy metabolism process through the tricarboxylic acid cycle and provide energy for the body. At the same time, it can also regulate blood sugar levels, promote the synthesis and release of glucose in the liver, and help maintain blood sugar stability.

Stimulation of Protein Synthesis: L-isoleucine can stimulate the secretion of insulin, and insulin can promote the uptake of amino acids and glucose by cells, thereby enhancing protein anabolism. For athletes and fitness enthusiasts, it helps increase muscle mass and strength.

V. Application Fields

Food Industry: As a nutritional fortifier, it is added to various foods such as bread, biscuits, beverages, etc., to improve the nutritional value of the foods. In addition, it can also improve the flavor and taste of foods.

Feed Industry: It is an important feed additive that can improve the protein utilization rate of feeds, promote the growth and development of animals, and enhance the production performance and immunity of animals. It is widely used in the feeds of livestock and poultry such as pigs, chickens, and cows.

Pharmaceutical Industry: It is used to synthesize a variety of drugs, such as antibiotics, hormones, etc. In addition, L-isoleucine can also be used as a drug carrier to improve the stability and bioavailability of drugs.
