    Product Introduction

    L-proline (proline for short) is one of the twenty amino acids of human body protein synthesis, colorless to white crystal or crystalline powder, smelly, slightly sweet, soluble in water and ethanol, insoluble in diethyl ether, butanol and isopropanol, soluble in inorganic acid. Amino acids are a general term for a class of organic compounds containing amino groups and carboxyl groups. The existence of amino acids in the human body not only provides an important raw material for the synthesis of proteins, but also provides a material basis for promoting growth, conducting normal metabolism and maintaining life.


    Calcium L-threonate can significantly increase the positive expression rate of type I collagen mRNA in chondrocytes and osteoblasts, significantly increase the positive expression rate of chondrocytes in articular cartilage and epiphyseal cartilage, promote the growth of chondrocytes, and increase the amount of bone collagen. , promote bone formation, cartilage matrix production and proteoglycan synthesis, and can also promote the formation of bone nutrition blood vessels and improve bone microcirculation.L-threonate is widely found in plants, human gastric acid and uric acid. It is a degradation product of L-ascorbic acid. Calcium L-threonate can be used as a nutritional fortifier and calcium supplement.

    Product Feature

    1. Plant cold resistance
    Proline (Pro) is one of the components of plant proteins, and it can be widely found in plants as free. Under drought and saline stress conditions, proline is greatly accumulated in many plants. In addition to serving as an osmotic substance, the accumulated proline also plays an important role in stabilizing biological macromolecular structure, reducing cellular acidity, relieving ammonia toxicity, and serving as a means to regulate cellular redox as an energy bank.

    2. Free radical scavenger
    Thus, it plays a protective role in the growth of plants under osmotic stress, and for the accumulation of another important osmotic material in the vacuole, proline can play a role in regulating the cytoplasm osmotic balance.

    3. The restorative role of tooth enamel
    A repetition of a simple amino acid in the center of the protein, according to a new study at the University of Illinois.
    In amphibian and animal models, proline repeats were compared. They found that when the repeats are short, such as in frogs, the teeth will not produce enamel prisms (enamel prism), and that these structures are important for the firmness of the teeth. Concontrast, when the protein repeats are long, they assemble a series of molecules to help enamel crystal growth.

    4. Good flavor
    Flavor agent, coheat with sugar amino monohydrogen group reaction, can produce substances with special aroma

    5. Safe and non-toxic
    Compound amino acid is one of the raw materials. For malnutrition, protein deficiency, severe gastrointestinal diseases, burns, and protein supplementation after surgery. There were no significant toxic or significant side effects.
