Types of Amino Acid
The amino acids produced by our company mainly include the following types:
Industrial Grade L-Aspartic Acid
Industrial grade L-Aspartic acid (chemical formula: C₄H₇NO₄) is a naturally occurring acidic amino acid classified as a non-essential amino acid. The industrial-grade product is produced via microbial fermentation or enzymatic catalysis, achieving a purity of 98%-99%. It combines cost-effectiveness with stability, making it ideal for large-scale industrial applications.
Food Grade DL-Aspartic Acid
DL-aspartic acid can provide additional amino acid nutrition for food, helping to enhance the nutritional value of food. It can improve the texture and taste of food, make food more soft and delicious, enhance the consumer's eating experience.
Food Grade Amino Acid
Food grade amino acids are widely used because of their natural sources, nutritional fortification and functional diversity, and have become a key ingredient in modern food innovation.
Health Benefits of Amino Acid
Providing the body with energy
Isoleucine and valine, in particular, are good sources of energy to fuel the body.
Enhancing the musculoskeletal system
Isoleucine and valine assist with healthy muscle function, while leucine works to repair muscles. Lysine promotes calcium absorption needed for bone growth.
Regulating digestion
Your body produces histamine to help your digestive system work properly. You need histamine to histidine to help generate histamine.
Enforcing healthy sleep/wake cycles
Erratic sleep habits caused by issues such as insomnia, sleep apnea, and stress, can take a toll on your overall health. Histidine and tryptophan help you maintain normal circadian rhythms for a good night’s sleep.
Supporting the immune system
Histidine, lysine, and threonine help boost immunity so your body can better fight off viruses.
Producing neurotransmitters
These chemicals are the nervous system’s way of communicating with the body, regulating everything from appetite to mood. Phenylalanine not only produces some neurotransmitters but other types of amino acids, too.
Stimulating the growth of healthy skin, nails, and hair
Collagen and elastin keep your complexion looking soft and supple. These two proteins also encourage hair and nail growth. Lysine assists with collagen production, while threonine helps generate collagen and elastin.
Producing hormones
Amino acids such as lysine are useful for maintaining healthy hormone levels. Examples of amino acid hormones include epinephrine and norepinephrine, which oversee the body’s stress response, and thyroxine, which plays a role in metabolism.
Maintaining a healthy weight
Methionine governs our metabolic rate and can also help with detoxification, while threonine is key for metabolizing fat.
Balancing your moods
Tryptophan jump-starts the production of serotonin, a hormone that’s essential for feeling happy and well-adjusted.
Applications of Amino Acid
Active Pharmaceutical Ingredients (APIs)
There are pharmaceutical products that make use of amino acids themselves, and products that are synthesized and manufactured using amino acids as starting materials. Amino Acids are also used in infusion solutions, in addition to tablet and granulated forms, and are an essential part of modern medical treatments.
Medical Foods / Medical Nutrition
Amino Acids are used as a way to provide a concentrated, specific and efficient intake of required nutrient components in medical foods for malnourished patients, elderly people with lower digestive capabilities, as well as in other uses.
Dietary Supplement / Health Foods / Functional Foods & Beverages
Amino Acids are used for compensating amino acid deficiencies, as well as in supplements that make use of the specific function of amino acids. Products are sold in tablet, granular and capsule forms. These products were once mostly used by athletes, but they are now popular among the wider public for everyday workout and health maintenance.
Cosmetics
Amino Acids are used in cosmetics for their unique moisturizing effect and pH levels. Amino acid derivatives are also used for their stability and absorbency.
Culture Medium
Recently, pharmaceutical products research and manufacture using cell culture process have become very popular. Amino Acids are essential components of cell culture medium. Amino Acids are considered to be indispensable to cell growth and production of antibodies and proteins.
Industrial Production of Amino Acids
Chemical synthesis
Amino acids can be produced by chemical synthesis, enzymatic catalysis, extraction from natural sources, or fermentation. Chemical synthesis is often used in industry for the mass production of specific amino acids. However, the major drawback of this technique is that it produces two forms of the amino acids called enantiomers which need to be separated before they can be used. This method can therefore only be used when the enantiomer of the amino acid is unimportant for the intended use.
Fermentation
Fermentation is currently only used for lysine and glutamic acid as certain mutant bacteria strains are needed which are difficult to produce. Glutamic acid can be modified with the addition of sodium hydroxide to produce monosodium glutamate.
