There is a general agreement that the experimentally determined molecular weight (MW) of caseinomacropeptide (CMP) is greater than the theoretical MW. Some studies suggest that this is due to a pH-dependent aggregation of monomeric CMP. How this aggregation is influenced by pH is not understood. This study was carried out to study the nature of CMP aggregates and to clarify which conditions affect aggregation of CMP. The apparent MW of CMP at different pH values was determined using size… 
REVIEW: ISOLATION AND PURIFICATION OF MILK WHEY GLYCOMACROPEPTIDE
The objective of this work was to review the isolation and purification methods of glycomacropeptide (gmp). This peptide is formed during enzymatic coagulation of milk, using chymosin. Aspects such

Characterization of bovine kappa-casein fractions and the kinetics of chymosin-induced macropeptide release from carbohydrate-free and carbohydrate-containing fractions determined by high-performance gel-permeation chromatography.
TLDR
The trichloroacetic acid-soluble reaction products were analysed by high-performance gel-permeation chromatography and two components appeared to be multiply-phosphorylated, but did not contain NeuAc; the possible significance of this finding in relation to the mode of phosphorylation and glycosylation in vivo is discussed.

Comparative study of methods for the isolation and purification of bovine κ-casein and its hydrolysis by chymosin
Summary κ-Casein was purified from a single batch of whole acid casein (κ-A variant) using different methods in order to compare their merits in producing a purified material with a carbohydrate and
Structural features and reversible association of different quaternary structures of β-lactoglobulin
TLDR
Evidence of reversible association was found for all the proteins with a very similar concentration dependence, indicating that the weak forces involved in this association were different fr...
Purification of κ‐Casien Glycomacropeptide from Sweet Whey with Undetectable Level of Phenylalanine
TLDR
The purified GMP was of high purity, with its amino acid composition showing undetectable levels of phenylalanine, tyrosine and arginine, the amino acids that do not occur in bovine GMP.
Modifications occur at different structural levels during the heat denaturation of beta-lactoglobulin.
TLDR
A general mechanism for the formation of early reactive species in heat-treated beta-lactoglobulin at neutral pH is proposed which stresses the relevant role of a highly hydrophobic, molten-globule-like free monomer that has an exposed sulfhydryl group on its surface.
