Trans-4-Hydroxy-L-Proline Market Summary
Introduction
The Trans-4-Hydroxy-L-Proline market centers on the production and application of Trans-4-Hydroxy-L-Proline, also known as L-Hydroxyproline or simply Hydroxyproline, a non-essential amino acid that serves as a crucial building block for collagen synthesis and various biochemical processes. This amino acid derivative represents one of the most abundant amino acids in collagen, comprising approximately 10% of collagen's amino acid content, making it essential for maintaining structural integrity of connective tissues, skin, bones, and blood vessels.
Trans-4-Hydroxy-L-Proline is primarily produced through biotechnological processes, including fermentation using genetically modified microorganisms, chemical synthesis from L-proline, and extraction from collagen hydrolysates. The compound demonstrates excellent water solubility, stability under normal storage conditions, and bioavailability when administered orally or incorporated into formulations. Its applications span across pharmaceuticals for joint health and wound healing, cosmetics for anti-aging and skin repair, food and nutrition for functional foods and dietary supplements, and various other industrial applications.
According to industry data, Shandong Jinyang operates hydroxyproline production with designed capacity of 500 tons per year and actual production of 250 tons per year. In 2024, the company added 100 tons per year of new hydroxyproline production capacity, increasing total production to 350 tons per year after expansion. Henan Julong maintains hydroxyproline production capacity of 500 tons per year, representing significant manufacturing presence in the Chinese market.
Hydroxyproline demonstrates wide application potential across food, cosmetics, dietary supplements, and pharmaceutical sectors. In food applications, hydroxyproline can be used as a food additive in cakes, bread, fruit juices, seasonings, and ice cream products, enhancing food texture and improving raw material utilization efficiency. In pharmaceutical applications, hydroxyproline can treat arthritis and synthesize essential collagen proteins required by the human body.
