Proteins are polymers of amino acids linked together through a peptide bond.. The shape and thus the function of a protein is determined by the sequence of its amino acids. Digestion of proteins produces amino acids, some of which are essential to the nutritional well being of the human.
Like carbs & fats these also provide energy but due to the presence of nitrogen in their structure they perform one of the most vital functions needed for a healthy life i.e. for building up of body's cells & tissues & for repairing & maintaining the worn out tissues. It also helps in synthesis of antibodies, enzymes, & hormones.
Animal sources of proteins are of better quality are readily absorbed & utilized by the body. These include milk & milk products, eggs, meat, poultry, fish, liver & an exception is soybean, which is a plant source. Plant sources include cereals, pulses, dry fruits, nuts, beans etc.
Daily requirement of protein is 1g/kg body weight. For e.g. A normal adult man of 60kg will require 60gm of protein. However, in stage of growth or illness requirement is increased.
The Function of Protein Includes:
- repair tissue
- make hormones
- antibodies and enzymes
- help balance acid-base, fluid and electrolytes
- provide some of the body’s energy
