چکیده
本稿では,牛乳タンパク質について栄養機能の観点から概説する。牛乳はカルシウムを多く含む食品として知られているが,良質なタンパク質を含む食品でもある。牛乳のタンパク質は,カゼインとホエイタンパク質に大別される。カゼインは,牛乳中でカゼインミセルと呼ばれる特徴的な構造を形成し,仔の骨の成長に必須となるリン酸カルシウムを体内に運搬する重要な役割を有している。一方,ホエイタンパク質には多くの種類のタンパク質が含まれる。主要な成分に,β-ラクトグロブリン,α-ラクトアルブミン,ウシ血清アルブミン,ラクトフェリン,ラクトパーオキシダーゼがあり,それらの多くも,仔を育てるための何らかの役割を有している。また,主要成分でなくとも,乳塩基性タンパク質(MBP)のようにユニークな機能を有するタンパク質が発見されている。さらに,牛乳タンパク質は消化吸収にも興味深い特徴がある。ホエイタンパク質は強固な構造を有するものが多く,胃を速やかに通過して腸管で分解,吸収される。一方,カゼインは胃で凝固するためゆっくりと分解,吸収される。このような消化吸収特性の違いから,牛乳摂取時には,タンパク質合成が速やかに開始され,かつ長く持続するという優れた特徴を有している。

Health-Related Aspects of Milk Proteins
Milk is an important component of a balanced diet and contains many valuable constituents. A considerable part of the milk healthbenefits is related to its proteins, not only for their nutritive value but also for their biological properties. Scientific evidence suggests that anticarcinogenic activities, antihypertensive properties, immune system modulation, and other metabolic features of milk...

Bovine milk oligosaccharides have several potentially important biological activities including the prevention of pathogen binding to the intestinal epithelial and as nutrients for beneficial bacteria. It has been suggested that milk oligosaccharides are an important source of complex carbohydrates as supplements for the food and the pharmaceutical industries. However, only a small number of st...

The RNase (EC 2.7.7.16) in bovine milk was partially purified from milk whey. The basic properties and the hydrolyzing specificity of this enzyme were studied. This enzyme was heat stable. When RNA was used as the substrate, the pH optimum was 7.5 and 3'nucleotides were produced, but the extent of the hydrolysis stopped at 31 per cent and core was left. C! and U! were hydrolyzed but purine cycl...
