2. Physical & Chemical Properties
Physical Properties
- Appearance: White crystalline powder, odorless
- Taste: Slightly sour
- Solubility: Easily soluble in water; slightly soluble in hot ethanol; insoluble in cold ethanol, ether, benzene
- Melting Point: Decomposes above 203 ℃ without distinct melting point
- UV characteristic: No obvious ultraviolet absorption in aqueous solution
- Hygroscopy: Slightly hygroscopic under high humidity environment
- Crystal form: Fine granular crystal recrystallized from water
Chemical Properties
- Molecular structure: Short-chain aliphatic amino acid, contains terminal amino group and carboxyl group, neurotransmitter structure
- Amphoteric property: Has amino and carboxyl groups, can form salts with acid and alkali, exists as zwitterion in neutral water
- Condensation reaction: Amino group condenses with aldehydes, carbonyl compounds; carboxyl group esterifies with alcohols
