They are usually used to pack powder. And they can prevent sunshine and water from getting bad.
The hard carton can protect your products from crashing and getting wet.
L-isoserine is a serine derivative.
Crystallization. Soluble in water.
Used as biochemical reagent, food additive, used in cosmetics industry.
Amino acids and amino acid derivatives have been commercialized as energy supplements. They affect the secretion of anabolic hormones, fuel supply during exercise, mental performance during stress-related tasks, and prevent exercise-induced muscle injury. They are considered as beneficial dietary substances.
Isoserine is a chemical, also known as 2-hydroxy-β-alanine; β-aminolactic acid; 3-amino-2-hydroxypropionic acid.
There are three optical isomers.
(1) L-isoserine: Crystal. Melting point 199~201℃(decomposition); Optical rotation -32.58°(in water); Soluble in water; Brucine salt was prepared from racemic isserine and then separated to prepare it. Its derivatives: N-benzoyl compounds melting point 107~109℃, rotation [α]D-30.03°.
(2) D-isoserine: crystallization; Decomposition at 199~201℃; Specific curl 32.44°(water) preparation method is the same as (1); Its N-benzoyl derivative C3H5O3(NHCOC6H5) has a melting point of 107~109℃ and a rotation of +32.44°(in water).
(3) DL-isoserine: columnar crystal; Melting point 248℃(decomposition); Ka (25 ℃) 5.37 x 10-10; Kb (25 ℃) 6.03 x 10-12; Dissolve in hot water; It reacts with hydrogen peroxide to form aminoacetaldehyde. Reacting with nitrite to form glycolic acid; Preparation method: amino acetaldehyde and hydrogen cyanide reaction to produce cyanoalcohol, hydrolyzed with hydrochloric acid, its derivatives :(1) ethyl ester, needle crystal, melting point 75℃, insoluble in ether; (2)N- benzoyl, crystal, melting point 151℃.
