Description

L-Lysine-L-glutamate (also known as L-lysyl-L-glutamic acid, English name: Lysylglutamic acid, H-Lys-Glu-OH) is a dipeptide amino acid derivative formed by the linking of the essential amino acid L -lysine and L-glutamic acid via a peptide bond. Its CAS number is 45234-02-4, with the molecular formula C₁₁H₂₁N₃O₅ and a molecular weight of 275.30. It possesses the structural characteristics of both amino acids, is mild in nature, and has good water solubility, making it a commonly used basic raw material in the fields of amino acid derivatives and peptides. This product is a high-purity (≥99%, as determined by HPLC) white crystalline powder that can be widely used in scientific research, as a pharmaceutical intermediate, in nutritional supplement products, and in the development of cosmetic formulations.

Key Effects

As an amino acid derivative in dipeptide form, L-lysine-L-glutamate is valuable mainly in two aspects: "nutrient supply" and "synthetic precursor". Compared with free amino acids, its dipeptide structure enables easier absorption and utilization via peptide transport pathways, while fully retaining the respective functional properties of lysine and glutamate. It can serve as a source of amino acid nutritional supplementation as well as a basic material for polypeptide synthesis and biochemical research, making it a versatile amino acid raw material.

Specifically, its functions in applications include:
Amino acid nutrient source: It provides both lysine (an essential amino acid for humans) and glutamate, and can be used for the development of amino acid nutrition-related products.
Advantage of dipeptide absorption: The dipeptide structure can be absorbed through peptide transport pathways and exhibits good performance in studies related to absorption and utilization efficiency.
Precursor for polypeptide synthesis: As a dipeptide with a well-defined structure, it acts as a fundamental building block for polypeptide synthesis and the development of amino acid derivatives.
Mild skin-friendly property: Amino acid ingredients feature mild properties and good water solubility, suitable for incorporation into various skincare formulations.

Applications

L-Lysine-L-Glutamate is used across a wide range of fields, including pharmaceuticals, food and nutrition, cosmetics, and scientific research. As an amino acid derivative with a well-defined structure and high safety profile, it serves as both a common biochemical reagent in laboratories and a frequently used ingredient in nutritional products and skincare formulations, with stable downstream demand and a wide range of applications.

1. Pharmaceutical Intermediates: Used in the research, development, and production of peptide drugs, amino acid preparations, and formulas for special medical purposes.

2. Food and Nutrition: Used as a nutrient-fortifying ingredient in the development of functional foods and amino acid supplements.

3. Cosmetic Ingredients: Used in moisturizing and conditioning skincare formulations; amino acid-based ingredients are gentle on the skin and have good compatibility with other ingredients.

4. Scientific Research: Used in biochemical research in areas such as dipeptide absorption and metabolism, protein nutrition, and enzymology.
