Descrição geral

Casein is an amphiphilic protein.[1]
Casein, a phosphoprotein, is the principal protein component of milk which is almost entirely expressed in the lactating mammary gland.[2] In bovine milk they are classified according to their calcium sensitivity: αs1-, αs2-, and β-caseins precipitate in the presence of calcium; whereas κ-casein remains in solution. [3]

Aplicação

Casein, Hammarsten bovine has been used as a substrate for Aplysia californica calpain to study its activity.[4]
The product is useful as a protease substrate.

Ações bioquímicas/fisiológicas

Casein is useful in food industries and non-food applications. It has the property for emulsification, foam formation, and stabilization, water-binding, and gelation. Casein is also considered heat and acid-stable.[1]
Partial gastrointestinal digestion of casein is a rich source of bioactive peptides, such as β-casomorphin. However, bovine casein is not homogeneous; variants A1 and B do lead to production of β-casomorphin 7 production, while A2 does not.

Questions

  1. 製薬会社で医薬品の品質試験を行なっている者です。このカゼイン(Hammerstein)において、日局等の公定書に基づいて赤外吸収スペクトル測定法の臭化カリウム錠剤法の試験を実施した実績がありますでしょうか。もしなければ、実施実績のある他のカゼイン(Hammerstein)製品の取扱いはございますでしょうか。ご回答お願いいたします。

    1 answer
    1. There are currently two Hammerstein versions of Casein available, E0789 and 1.02242. Neither of these products are tested according to the JP.
