Calf liver is a high protein food with a total percentage of 47% of your daily protein intake, in as little as 113 grams.
Proteins are polymer chains made of amino acids linked together by peptide bonds. In nutrition, proteins are broken down in the stomach during digestion by enzymes known as proteases into smaller polypeptides to provide amino acids for the body. This includes the essential amino acids that cannot be biosynthesized by the body itself. Therefore, protein from one's diet should provide both essential and non-essential amino acids for protein synthesis. Most animal and certain vegetable proteins are considered complete proteins with a full complement of essential amino acids in adequate proportions. People who avoid animal products for religious and health reasons may practice protein combining to get the essential amino acids in their diet.
Protein is a nutrient needed by the human body for growth and maintenance. Aside from water, protein is the most abundant molecule in the body. Protein is found in all cells of the body and is the major structural component of all cells in the body, especially muscles. This also includes body organs, hair and skin. Proteins also are utilized in membranes, such as glyco-proteins. When broken down into amino acids, they are used as precursors to nucleic acid and vitamins. Hormones and enzymes are also formed from amino acids in which they help regulate metabolism, support the immune system and other body functions. Finally, protein is needed to form blood cells.
There are many different sources of protein ranging from whole protein foods such as milk, meat, fish, egg, and vegetables, to a variety of protein powders such as casein, whey, egg, rice and soy. Protein powders are processed and manufactured from alternative sources of protein. Protein powders may provide an additional source of protein for exercising muscles. This type of protein is important in terms of its influence on protein metabolic response and possibly on the muscle's exercise performance. The different physical and or chemical properties within the various types of protein may affect the rate of protein digestion. As a result, the amino acid availability and the accumulation of tissue protein is altered because of the various protein metabolic responses.
