Protein is an essential nutrient for the body, it is indispensable energy and nutrient source. We make our proteins by decomposing the intake food to elemnts, amino acids and we make new proteins from them. So we need these elements called amino acids. Our proteins play an important role in fabric construction (muscle, tissue), in water binding, in regulating the acid-base balance. In addition, they are components of several materials and they are necessary for the formation of different compounds.
The components of protein are the amino acids. 20 types of amino acids are known of which 9 are essential, so-called essential amino acids. They can not produce by the body but must be intook to our body with food while not essential amino acids can be produced by the body with the help of essential amino acids.
The following amino acids are essential:
- Phenylalanine, eg. milk casein. Antidepressant and analgesic effect are known.
- Isoleucine: can be found in egg, soy protein, seaweed, turkey, chicken, lamb, fish and cheese.
- Leucine: can be used in liver, adipose tissue and muscle tissue, in the latter two is seven times more than the liver. It can be found in button mushroom as well.
- Methionine: can be in high levels in sesame seeds, fish, meat, some plant seeds. In vegetables as spinach, potatoes and cooked sweet corn.
- Threonine: in large quantities there is in lump, poultry, fish, meat, lentils and sesame seeds.
- Tryptophan is mainly in chocolate, oatmeal, dried dates, milk, yogurt, cottage cheese, red meat, eggs, fish, poultry meat, sesame, chickpeas, sunflower seeds, pumpkin seeds, peanuts found.
- Valine is found in cottage cheese, cheese, fish, poultry, peanuts, sesame seeds, mushrooms and lentils.
Mushrooms are excellent source of protein, including white and brown button mushrooms and oyster mushroom contains the most. Research shows that the amino acid composition of mushrooms is similar to animal protein making it a great meat alternative for vegetarians. Regarding the amino acids, mushrooms are rich in leucine, valine, glutamine, glutamic acid and aspartic acid.
The proportion of essential amino acids (all the amino acids in%) of the mushroom protein
Complete proteins are those proteins that comprise both the nine essential amino acids, so that the body can provide the amino acid needs of the organism as a sole source of protein, namely for the body they contain essential amino acids in sufficient quantities and proportions. Such as milk, eggs, fish and mushrooms.
The main symptoms of protein deficiency are:
- weight loss because the body is breaking and consuming their own proteins,
- liver damage,
- negative nitrogen balance,
- decrease in serum protein content,
- decrease of blood pressure.
So mushrooms are great source of protein because they contain most of the amino acids which make up proteins and their structure is similar to animal proteins so they are ideal for vegans and vegetarians to ensure the sufficient amount of protein for the body.
