What is the essential and non-essential amino acids

The human diet is subject not only to the law of daily calories, but also several equally important nuances. It is necessary to calculate the ratios of proteins, fats and carbohydrates, monitor the proportion of vitamins entering the body, and also find out which amino acids are required to be present in food and which can be consumed much less frequently.

Table of essential and non-essential amino acids

what amino acids are required to be present in food

First you need to understand what are the amino acids in general and why these organic protein compounds are so important for the body (or, more precisely, a certain part of them). What do professionals say?

  • Essential acids, among which 8 pieces are obligatory for a person, are otherwise called essential. They are not synthesized by the body, so they must come from the outside, from food. In some cases, assigned amino acids in pure form. Their value lies in the fact that they influence absolutely all internal systems. The antioxidant function is particularly pronounced.
  • Replaceable acids, whose number is greater - 14 pcs., Contrary to their name, should not disappear from the diet, however they can be produced by the body independently, therefore products may contain fewer of them. Their functions are the same as essential amino acids.

To better remember which elements you should definitely look for in food, and which may be secondary, read the table below.



Conditionally irreplaceable

























As you can see, there is a separate group of conditionally essential amino acids, elements of which are sometimes included in the category of essential. Why is this situation happening? The fact is that with acute need, both arginine and histidine are still synthesized in the body, but for this some of the essential amino acids will be involved. Accordingly, in the absence of the latter, they also become irreplaceable, that is, not produced. In addition, the group of irreplaceable arginine and histidine fall in children.

Why do we need amino acids?

Why do we need amino acids?

About the general causes of the value of these elements for the body it has already been discussed, but for a better understanding of what is happening, it is worthwhile to focus on certain elements. But before it is necessary to once again emphasize that those names that are not included in the list below are not useless - rather, they play a secondary role. However, they cannot be completely abandoned.

  • Valine takes part in nitrogen metabolism and regulates metabolic processes in muscle tissue, promotes their regeneration, and produces energy.
  • Leucine acts as a defender of the integrity of muscle tissue, as well as its regenerator, but it can also restore bone tissue, as well as the epidermis. It also normalizes glucose levels, contributes to the production of growth hormone.
  • Lysine is an integral part of most proteins, is involved in the formation of bone tissue, improves calcium absorption and tissue regeneration, and helps increase overall endurance and muscle strength. Women need it to improve the quality of hair and libido.
  • Isoleucine is required to prevent anemia, because it helps produce hemoglobin, and is also needed to adjust sugar, increase overall body endurance, and trigger regenerative processes in muscles.
  • Methionine helps to process fats, preventing them from being deposited on the internal organs and walls of blood vessels, improves digestion, is necessary for the treatment of arthritis and osteoporosis, elimination of toxicosis during pregnancy. It is also able to protect the body from radiation.
  • Threonine is required for the metabolism of proteins and fats, the production of collagen, strengthens the immune system, takes part in the work of the heart, prevents fats from being deposited in the liver.
  • Tryptophan allows you to produce serotonin, fights insomnia and mood swings, dulls the feeling of hunger.
  • Phenylalanine turns to tiriosin, which is involved in the development of neurotransmitters, and also improves mood, memory, concentration, reduces the degree of pain, reduces the feeling of hunger.

Amino acids have an increased value for people involved in sports, because they protect the body from injury. But the common man, far from high physical activity, needs to maintain their balance so as not to have problems with the immune system, metabolism and the state of the musculoskeletal tissue.
