Product Description

Brief introduction

L-hydroxyproline is a common non-standard protein amino acid. As the main raw material of the antiviral drug atazanavir, it has high application value. Hydroxyproline is generally used as a food additive (used as a sweetener in relatively small amounts), while in medicine, it is used as an intermediate in the Penam side chain in relatively large amounts.

Application

L-hydroxyproline is a natural component of animal structural proteins, such as collagen and Elastin. Several microorganisms producing proline trans-4- and cis 3-hydroxylase have been discovered and used for industrial production of trans-4- and cis 3-hydroxy-L-proline.

Chemical property

White flaky crystalline or crystalline powder. The unique sweetness in bitterness can improve the flavor and quality of fruit juice drinks, cool drinks, etc. It has a special flavor and can be used as a fragrance ingredient. Melting point 274 ºC (decomposition). Easily soluble in water (25 ºC, 36.1%), slightly soluble in ethanol.

Purpose

Flavor enhancer; Nutritional fortifiers. Fragrance. Mainly used for juice, refreshing beverages, nutritional beverages, etc.

APPLICATION&FUNCTION

L-proline benzyl ester hydrochloride and its derivatives are often used as asymmetric catalysts in organic reactions. The CBS reduction and proline catalysed aldol condensation are prominent examples.

L-proline is an osmoprotectant and therefore is used in many pharmaceutical, biotechnological applications.

In brewing, proteins rich in proline combine with polyphenols to produce haze.

L-proline is one of the important amino acids for synthesizing human protein. It is widely used in the food and medical industry, and is an important intermediate for synthesizing ACE inhibitors such as Captopril and Enalapril. It is also one of the important raw materials of amino acid transfusion.

L-proline has been used universally as food additive, catalyst and raw materials of fine chemical industry.








 

What is L-Hydroxyproline ?

L-Hydroxyproline is a nonessential amino acid derivative formed during post-translational protein modification through hydroxylation of the amino acid proline by the enzyme prolyl hydroxylase which requires vitamin C as a co-factor. Hydroxyproline is a major component of the protein collagen and plays a key role in the stability of the collagen triple helix. It can be used as an indicator to determine the amount of collagen. Increased hydroxyproline levels in the urine and/or serum are normally associated with degradation of connective tissue. Vitamin C deficiency decreases the conversion of proline to hydroxyproline, which leads to reduced collagen stability.L-Ornithine is an amino acid that plays an important role in the urea cycle. It plays an important role in the discharge nitrogen in the body. It has different names and forms such as L-ornithine and aspartate ornithine (OA). 
 

 

Function of L-Hydroxyproline

 

1.L-Hydroxyprolineis a major component of collagen.
2. L-Hydroxyproline can be used in medicine. L-Proline is one of the raw material compound amino acid infusion. It is used for malnutrition, protein deficiency, protein supplements serious gastrointestinal diseases, burns and after surgery. No significant side effects.
3. L-Hydroxyproline can improve plant cold tolerance.
4. L-Hydroxyproline can repair the enamel.
5. L-Hydroxyproline can be used as nutritional supplements, flavor enhancers. Occurring amino sugar were hot -carbonyl reaction, it can generate a special flavor substances.
