Introduction

C₃H₇NO₂ is a high-purity amino acid produced through controlled fermentation or enzymatic synthesis, providing a stable, water-soluble source of alanine for formulations that require consistent mixing and precise dosing.

Information

Structural Formula
L-Alanine (natural form)	CH₃CH(NH₂)COOH, α-aminopropionic acid.
D-Alanine (non-natural form)	Enantiomer, commonly found in bacterial cell walls.
Physical and chemical properties
Molecular weight	89.09 g/mol.
Melting point	297°C (decomposition).
Solubility	Easily soluble in water, slightly soluble in ethanol.
Isoelectric point (pI)	6.0, neutral amino acid.

Production Process

Microbial fermentation method (mainstream)
Strain	Corynebacterium glutamicum, Escherichia coli (genetically engineered).
Raw materials	Renewable resources such as glucose and corn starch.
Features	Environmentally friendly, high purity (>99%), in line with food grade standards.
Enzymatic synthesis	Use immobilized enzyme to catalyze the reaction, mild conditions, and few by-products.

Key Features
