L proline is one of more than 20 kinds of amino acids for human body to synthesize protein, and it belongs to α-imino acid. There are three forms of proline, DL-proline, L-proline, D-proline. In general, proline is commonly referred to as L-proline, a naturally occurring amino acid. It is colorless to white crystal or crystalline powder at normal temperature, slightly odorous, slightly sweet taste, easily soluble in water and ethanol, insoluble in ether, butanol and isopropanol, soluble in inorganic acids.

It is a non-essential amino acid, which exists in almost all proteins, and its content in the body is very rich, second only to glutamine and alanine. About half of the collagen in the body contains proline, which accounts for 30% of the protein in the body.

What Are Applications of L Proline

Used as food additives, feed additives, fertilizer additives, etc. Commonly used in various food, beverage, health products, feed, medicine, agriculture, industry, biochemical research, etc.

  1. Used in amino acid injections, compound amino acid infusions.
  2. For biochemical research.
  3. Nutritional supplements. Flavoring agent, co-heated with sugar to undergo amino-carbonyl reaction, can generate special flavor substances.
  4. Amino acid drugs. It is one of the raw materials of compound amino acid infusion, used for malnutrition, protein deficiency, severe gastrointestinal disorders, protein supplement after scald and surgery.
  5. It is an osmoprotectant. Therefore, it is used in many pharmaceutical and biotechnological applications.
  6. L-proline can act as a weak agonist for glycine receptors and NMDA and non-NMDA (AMPA/kainic acid) ionotropic glutamate receptors.It is considered a potential endogenous excitotoxin. In plants, proline accumulation is a common physiological response to various stresses, but is also part of the developmental program of reproductive tissues.
  • Regulate the osmotic potential of cells. Under salt stress, plant cells will easily lose water due to the decrease of intracellular water potential. As a highly soluble amino acid, it has no charge in normal pH. Under osmotic stress, the amino acid can utilize its strong water-absorbing ability to enhance the water-holding capacity of cells.
  • Stabilizer protein. Proline has no charge in plants and has dipolarity. It will not be inserted into the hydrophobic phase of protein molecules to cause protein denaturation. It can also improve the water environment of the cell membrane and enhance the stability of the membrane structure. Among many soluble osmotic adjustment substances, L proline is the only soluble substance that can protect plants from free radicals and singlet oxygen molecules.
  • As nitrogen and carbon frame. Provide energy for plants after the stress is relieved, and help plants resume normal growth. In addition, L proline fertilizer may act as an antidote to ammonia during plant damage.

Proline levels are reduced in long-distance runners and other endurance athletes. Professional athletes may need to take the amino acid in supplements to avoid loss of muscle mass. Because the human body disassembles muscles for energy when the glucose supply is low.

It is a non-essential amino acid because the body can produce it from glutamic acid, so healthy people with a balanced diet are rarely deficient in this amino acid.

People recovering from traumatic injuries, especially severe burns, may require additional proline supplementation.

People who suffer from body pain due to insufficient cartilage or collagen deficiency can also take to relieve discomfort.

Benefits of L-Proline Supplement and Medications

  • Help heal wounds and repair skin.
  • Aid digestive Health.
  • Help prevent joint pain.
  • For the treatment of cardiovascular system diseases.
  • Contribute to a healthy metabolism and fight inflammation.
  • L proline supplement can also help the body break down protein, which is important for creating healthy cells in the body and maintaining the healthy growth of skin and connective tissue.
  • It is needed in collagen to produce Hydroxyproline and Hydroxylysine, which help heal cartilage and provide cushioning for joints and spine. For this reason the nutritional supplements are effective in the treatment of osteoarthritis, persistent soft tissue tension, chronic back pain and other conditions.
