What Is Protein and How Much Daily Requirement Protein Intake We Must Meet

Should we ask why the egg white protein or substance is very important for the body? Of course because it is one of important substance. That is why we should know daily protein intake, to avoid protein deficiency that may caused several dangerous diseases. In addition, because of the protein, the living protoplasm in the cell was formed. Protoplasm will continue to suck and use energy. Most of this energy is required for the growth of the cell itself and the rest to activity, as well as to generate heat. That's what makes us warm and alive. During our life, the cells will continue to maintain body temperature regardless of the weather. Well to perform these tasks, the cells must be supplied with proteins and carbohydrates.



Protein Definition
Protein is part of all living cells and the largest part of the body after water. Fifth part of the body is protein, present in half of the muscle, fifth in the bone and cartilage, tenth in the skin, and the rest in other tissues and body fluids. All enzymes, hormones, nutrients transporters that form proteins act as precursors largely coenzyme, hormones, nucleic acids, and molecules that are essential for life.

Meanwhile base on wikipedia site described, proteins are large biological molecules, or macromolecules, consisting of one or more chains of amino acid residues. Proteins perform a vast array of functions within living organisms, including catalyzing metabolic reactions, replicating DNA, responding to stimuli, and transporting molecules from one location to another. Proteins differ from one another primarily in their sequence of amino acids, which is dictated by the nucleotide sequence of their genes, and which usually results in folding of the protein into a specific three-dimensional structure that determines its activity.

Source of Protein 
Animal foods are a good source of protein, in both quantity and quality, such as eggs, milk, meat, poultry, fish, and shellfish. Sources of vegetable protein is soy beans, and processed products such as tempeh and tofu, and other beans (read more at best list of high protein foods article).

Benefits of Protein
Protein for body is a builders substance, for example in children is instrumental to the development of body and brain cells. While in adults, in the event of cuts, bruises and so forth, then the protein can rebuild damaged cells. Isoflavones contained in soy is glycoside compound that soluble in water and anti-aging (anti-aging), and anti-oxidant (anti-free radicals).


Daily protein intake

Still in debate, experts have studied to determine exactly how much protein our bodies need. Many healthcare organizations have been doing regular research, what amount should be recommended for daily protein intake. Recommended Requirements vary from person to person. For example, the protein requirement for adults is different than young children grow. There are several factors to consider when deciding the recommended daily intake of protein, such as sexual activity, physical condition, age, and activity level. Below are daily protein intake based on activity level, taken from arizona.edu.
