Abstract

Quasi-elastic light scattering shows an initial decrease of about 5 nm in the hydrodynamic radius of casein micelles after adding chymosin, assuming the decrease to be equal for all micelles. This is consistent with the hypothesis that casein micelles have a hairy outer layer that is partly made up of the caseino-macropeptide part of kappa casein.

摘要

准弹性光散射显示，添加凝乳酶后，酪蛋白胶束的流体动力学半径最初减小约5纳米，假设所有胶束的减小幅度相同。这与酪蛋白胶束有一个毛发状外层的假设一致，该外层部分由κ-酪蛋白的酪蛋白巨肽部分组成。
