Nomenclature of the Proteins of Bovine Milk—First Revision

Abstract

Report of the 1959 American Dairy Science Association''s Committee on Milk Protein Nomenclature. The nomenclature status of [alpha]-casein and [beta]-lactoglobulin was considered. Alpha-casein has been separated into Ca-sensitive and Ca-insensitive fractions, designated by various symbols. Preferred nomenclature was not recommended at this time in view of the complexity of the problem. A listing of the isolated fraction was given. [beta]-Lactoglobulin, obtained from mixed milk, is composed of at least 2 forms of [beta]-lactoglobulin which are genetically determined and are designated [beta]-lactoglobulin A and B, discernible by paper electrophoresis in veronal buffer at pH 8.6, where type A constitutes the leading component.
