The word 'protein' was oined by Jon's Jacob Berzelius in 1838. For the previous 150 years, however there had been the concept of an ' animal substance' slight variants of which were thought to make up muscles, skin and blood. Proteins are essential for the human body. There is no life without protein. The efficiency or degree to which dietary proteins can be used for building parts of the human body is determined principally by the type and relative amounts of the Amino acid present in the particular protein molecule. They are one of the building blocks of body tissue and also serve as a fuel source. Protein is essential for the growth and repair of the body and maintenance of good health. The amount of protein we need are changes during the life time. Different food contains different amount and different combinations of amino acids sequences (British nutrition foundation,2012).…show more content…
Dietary protein is considered an important macronutrients, ideally contributing 10-15%to the total energy supply. Protein is considered the most effective macronutrients in thermogenesis via the regulation of energy intake and satiety. Moreover protein are vital for human metabolism as a source of essential Amino acid. (Christopher J. Bates et al.,2011). Proteins are large molecules made up of long chains of amino acids. Amino acids are the building blocks of proteins. The biochemical activity of proteins is characterised by their individual structure, size and shape. These factors are determined by the sequence and characteristics of the constituent amino
