Lysalbinic Acid
Historical document, translated for reference. It reflects medical knowledge of the 1920s–30s and is not medical advice.
Summary
Lysalbinic acid is a product of treating egg white or casein with sodium hydroxide solution, representing a mixture of substances rather than a chemically individual body. Unlike protalbinic acid, it is readily soluble in water and serves as a protective colloid for preparing colloidal metal solutions, such as silver preparations like collargol.
Encyclopedia entry (1928–1936)
LYSALBINIC ACID, a product of treating egg white or casein with a NaOH solution. In all probability, lysalbinic acid is not a chemically individual body, but a mixture of substances possessing similar physical properties. Lysalbinic acid, in contrast to protalbinic acid, which is also always formed during the alkaline hydrolysis of proteins, is readily soluble in water. It serves as a protective colloid for obtaining colloidal solutions of metals and is therefore used in the manufacture of silver preparations, in particular collargol.
