Amino acids are protein building blocks that have a variety of activities in the body. Amino acids are chemical molecules featuring the amino group and carboxyl functional groups, as well as a side chain that is unique to each amino acid.
Amino acids are divided into two categories based on the body’s ability to manufacture them: essential amino acids and nonessential amino acids. Essential amino acids, as the name implies, cannot be produced by the body and must be obtained through food. Nonessential amino acids, on the other hand, are so named because they can be produced by the body
Essential Amino Acids
Essential amino acids serve a variety of activities in the body. Essential amino acids, for example, are frequently utilised to make muscle and other important physiological tissues, such as organ cells and skin cells through collagen production.
Every day, an adult body requires approximately 0.5 g of protein per pound of lean body weight. The more amino acids you require to maintain your body bulk, the bigger you are. This is why vital amino acids are found in many workout and fitness products. 9 out of the 20 amino acids required by live cells and tissues are not synthesised by humans, including babies. They can only be gained through dietary means. Essential amino acids are those that are required for life.
Examples of essential amino acids are; lysine, methionine, leucine, valine, phenylalanine, etc.
Non-Essential Amino Acids
Although nonessential amino acids may not appear to be important, they are. In reality, they are just as important as essential amino acids in the traditional sense. Nonessential amino acids, alike their essential counterparts, play an important role in your body. Many non-essential amino acids, for example, are utilised to assist the growth and repair of healing and regeneration, as well as to aid in the production of new red blood cells in your body. Your body would be unable to make new blood without non-essential amino acids.
Furthermore, because nonessential amino acids are essential for the normal operation of your immune system, they aid in disease prevention. Your body also employs non-essential amino acids to make hormones.
Examples of non-essential amino acids are; aspartic acid, serine, alanine, glycine, glutamic acid, tyrosine, etc.
Essential and Non-Essential Amino Acids: Difference
- Essential amino acids are a class of amino acids that cannot be synthesised by the human body from metabolic intermediates. Simply, essential amino acids are those that the body cannot produce on its own. Because the organism lacks the metabolic mechanisms to produce certain amino acids, they must be obtained through diet. “Indispensable amino acids” is another name for essential amino acids.
- Protein-energy malnutrition, which manifests as marasmus or kwashiorkor, is caused by a lack of essential amino acids. This shortage can have an impact on the functions of all of the body’s organs, including the brain and immune system, raising the risk of infection. Meat, chicken, egg, cheese, milk, soya bean, tofu, and other animal products are good suppliers of essential amino acids.
- Nonessential amino acids (also referred to as “dispensable amino acids”), on the other hand, are amino acids that the organism can synthesise without using the essential amino acids. To put it another way, the body is capable of producing them. Dietary sources of non-essential amino acids are not required. Despite the fact that nature has hundreds of amino acids, only roughly 20 are required to build all of the protein cells in the human body. According to the text, selenocysteine is another amino acid that is thought to be the 21st acid. Selenocysteine is a relatively new amino acid that has the potential to be introduced into protein chains at the time of protein biosynthesis.
- Although glycine is classified as a non-essential amino acid, the human body requires sufficient amounts of vitamin B6 and an enzyme is known as serine hydroxy methyltransferase to create it. When the human body lacks vitamin B6, it is unable to synthesise glycine, which must be supplemented through the diet. Pyrrolysine is the 22nd amino acid, although it is not employed in the production of human proteins.
Conclusion
Finally, amino acids are used by animals and plants to make proteins, neurotransmitters, and hormones. There are 22 distinct amino acids with varying chemical properties, and each protein is made up of 50 to 2,000 amino acids united in a precise sequence based on genetic instructions. These amino acids are classified as essential or non-essential based on the human body’s ability to synthesise them. Finally, both essential and non-essential amino acids are necessary for maintaining physiological health and ensuring that your body can create new muscle fibers and repair tissue after a strenuous activity. If you want to promote muscle growth and attain your physical potential, look for supplements that contain all of the important essential amino acids.
