Where?The major milk proteins are synthesized in the mammary epithelial cells

mammary epithelial cells and are only produced by the

mammary gland.

But the immunoglobulin and serum albumin in milk are not synthesized by the epithelial cells.

They are absorbed from the blood


Слайд 4 High quality protein in cow milk is one

High quality protein in cow milk is one of the key

of the key reasons why milk is such an

important human food.

Caseins have an appropriate amino acid composition that is important for growth and development of the nursing young.

But sometimes most of the whey protein is not digested in the gut. This leads to an allergy to milk proteins

Output caseinCasein may come out of solution, forming the gelatinous material

the gelatinous material of the curd.
This is part of the

basis for formation of all non-fluid milk products like cheese.

Casein molecules can also be separated from the whey by precipitation

whey by precipitation of the casein with acid or

by disrupting the micellar structure with a proteolytic enzyme

 Form the different types of cheese

Specific bacterial cultures are used to establish the conditions for lowered pH
