L-Proline is a naturally occurring amino acid and an important building block of proteins. As one of the proteinogenic amino acids, L-Proline plays a particularly important role in the structure of collagen, a major structural protein found in skin, connective tissue, cartilage and other parts of the body.
With its versatile properties and broad application potential, L-Proline is widely used in food, nutrition, cosmetics, pharmaceuticals, biotechnology and other industries.
For companies looking for a reliable L-Proline manufacturer and supplier in China, Dalian Sinobio Chemistry Co., Ltd. provides stable supply, competitive pricing and professional service.
L-Proline is the naturally occurring L-form of proline, with the chemical formula C₅H₉NO₂ and a molecular weight of 115.13 g/mol. Its CAS number is 147-85-3.
Unlike most amino acids, L-Proline contains a secondary amino group within a five-membered ring structure. This unique molecular structure gives L-Proline distinctive conformational properties and makes it particularly important in protein structure.
L-Proline is classified as a non-essential amino acid, meaning that the human body can synthesize it. It is also naturally present as part of proteins in food and biological tissues.
One of the most interesting characteristics of L-Proline is its close relationship with collagen. Collagen contains significant amounts of glycine, proline and hydroxyproline. These amino acids contribute to the characteristic structure and stability of collagen.
This is why L-Proline is relevant to a variety of industries connected with nutrition, skin care, connective tissue, protein research and biotechnology.But L-Proline is not only a laboratory or industrial chemical. Its applications can be found in products and industries that are closely connected with our everyday lives.
L-Proline is used in the food industry as a nutritional ingredient and flavoring/flavor-enhancing component. Because amino acids are naturally associated with proteins and nutrition, L-Proline can be found in applications involving: Nutritional products, Amino acid supplements, Functional foods, Food formulations etc.
L-Proline also has applications in cosmetics and personal care products. It is listed in cosmetic ingredient databases for functions including skin conditioning and hair conditioning.
Its connection with collagen makes proline particularly interesting for the cosmetics industry. Collagen is an important structural protein in the skin, while proline and hydroxyproline are major amino acids associated with collagen structure.
L-Proline can therefore be considered for formulations such as: Skin care products, Hair care products, Beauty and personal care formulations, Amino-acid-based cosmetic products
L-Proline has also been used in pharmaceutical and nutritional applications, including as a component of amino-acid formulations and as a starting material or intermediate in pharmaceutical chemistry. Its well-established role as a proteinogenic amino acid makes it valuable in biochemical research, nutritional formulations and pharmaceutical-related applications.
As a professional chemical supplier, Dalian Sinobio Chemistry Co., Ltd. provides L-Proline for customers in different markets and application fields.We focus on supplying competitive-quality L-Proline with stable production capacity and reliable supply.
