Determination of silk amino acids
1 Scope
This standard specifies the method for Determination of silk amino acid composition and content.
This standard applies to the determination of the silk in eighteen amino acids components. Aspartic acid (Asp), threonine (Thr), serine (Ser), Valley
Acid (Glu), glycine (Gly), alanine (Ala), valine (Va1), isoleucine (Ile), leucine (Leu), tyrosine (Tyr), benzene
Phenylalanine (Phe), lysine (Lys), histidine (His), arginine (Arg), proline (Pro) was measured using acid hydrolysis, cystine
(Cys) and methionine (Met) if the acid hydrolysis can not be accurately determined by measuring the oxidation hydrolysis method should be used, tryptophan (Trp) using alkaline hydrolysis
Determination. The minimum detection limits were 10pmol.

3 PRINCIPLE OF THE METHOD
Acid, alkaline hydrolysis. hydrolyzed silk protein amino acids occur in high-temperature acidic or alkaline solution, hydrolysis into usable ion exchange chromatography
Separation and determination method. Hydrolysis of. silk protein sulfur amino acids (cysteine, methionine), used by the oxidation of formic acid and aqueous hydrochloric acid
Solution Generation cysteic acid and methionine alum, chromatography separation and determination of these two products are available ion exchange.
4 Reagents and materials
4.1 Requirements
Concentrated hydrochloric acid (12mol/L) of pure class distinctions, other agents unless otherwise noted, were of analytical grade.
4.2 Water
In line with GB/T 6682 two water requirements.
4.3 Nitrogen
A purity of 99.99%.
4.4 Acid Hydrolysis
4.4.1 acid hydrolysis agent. concentrated hydrochloric acid is diluted with water to 6mol/L.
4.4.2 Refrigerant. liquid nitrogen, dry ice or dry ice acetone and ethanol.
4.4.3 diluted with buffer machine. concentrated hydrochloric acid is diluted with water to 0.02mol/L.
