Solubility: Amino acids are generally soluble in water, acid solutions and alkali solutions, and are insoluble or slightly soluble in organic solvents such as ethanol or ether. The solubility of amino acids in water varies greatly. For example, tyrosine has the smallest solubility. At 25°C, only 0.045g of tyrosine is dissolved in 100g of water, but the solubility of tyrosine is greater in hot water. Lysine and arginine often exist in the form of hydrochlorides because they are highly soluble in water and difficult to crystallize due to deliquescence. |
Preservation method: Store 2-8°C in a cool, dry, well-ventilated warehouse. Keep away from fire and heat. Keep out of direct sunlight. The package is sealed. It should be stored separately from acids and edible chemicals, and should not be mixed. The storage area should be equipped with suitable materials to contain leaks and avoid contact with oxides. |
