Eight essential Amino AcidsAmino acids play a vital role in the numerous functions of the body; they are the building block of protein. Twenty amino acids are needed by the body to build various proteins used in the repair, growth, and maintenance of body tissues. Some of these amino acids can be manufactured by the body itself and are called non-essential amino acids, while others must come from the diet and are called essential amino acids.
These classification of the amino acid whether essential or non-essential does not reflect its importance because all of the twenty amino acids are very important for health, instead this classification system is just a reflection of whether the body is capable or not of producing a particular amino acid.
All these amino acids keep us vibrant,
alive, and healthy. Any deficiency in a single amino acid will cause health problems for us; a single deficiency should be replaced to fulfill its functions.
The eight essential amino acids which can be produced by the body are as follows:
Lysine
This is one of the eight essential amino acids that is needed for the growth and the maintenance of nitrogen balance in the body. It is integrated into many proteins throughout the body and appears to help the body absorb and conserve calcium.
Methionine
This amino acid supplies sulphur and other compounds that the body needs for normal metabolism and growth. This is also one of the eight essential amino acids that belongs to a group of compounds called lipotropics or chemicals that help the liver process fats.
Phenylalanine
This one of the eight essential amino acids that serves as a building block for the variety of proteins that are manufactured by the body, and can be converted to L-tyrosine and subsequently to L-dopa, epinephrine, and norepinephrine.
Tryptophan this amino acid is a natural relaxant that helps ease insomnia by inducing normal sleep. It reduces anxiety and depression, helps in the cure of migraine headaches, helps reduce the risk of artery and heart spasms, helps the immune system, and works with Lysine to reduce cholesterol levels. It also aids in the production of antibodies and can be converted into Glycine.
Histidine
Histidine is one of the eight essential amino acids that are found in high concentrations in hemoglobin. It is very useful in treating anemia due to its relationship to hemoglobin. It has been used to treat rheumatoid arthritis and has also been linked to allergic response and has been used to treat allergy. It also assists in maintaining proper blood pH.
Isoleucine and Leucine
This essential amino acid is one of the three major Branched-Chain Amino Acids (BCAA), which are involved with muscle strength, muscle stamina, and endurance. Isoleucine is used by the muscle tissues as an energy source. It is also required in the formation of hemoglobin. It is a potent stimulator of insulin and helps in bone healing. It also promotes skin healing and modulates the release of Enkephalins, which are natural pain-reducers.
Valine
This amino acid is one of the three major Branched-Chain Amino Acids. BCAA levels are significantly decreased by insulin. Intake of high dietary sugar or glucose causes the release of insulin which in turn causes a drop in BCAA levels. This amino acid competes with Tyrosine and Tryptophan in crossing the blood-brain barrier. This amino acid is also actively absorbed and used directly by the muscle as an energy source.
Threonine
As one of the eight essential amino acids, this amino acid is required for the formation of collagen and helps prevent fatty deposits in the liver. It aids in the production of antibodies and can be converted to Glycine in the central nervous system. It also acts as a detoxifier and is needed by the gastrointestinal tract for normal functioning.
Amino Acid Metabolism
Overview Described for its complexity brought about by the large number involved, amino acid metabolism can actually be split into 20 protein block- builders that are significant for biosynthesis. Functioning as precursors for the...
Sulphur Containing Amino Acids
Amino acids are the basic structural units of all proteins and they play a very important role in manufacturing proteins. There are twenty known amino acids that are both essential and nonessential amino acids. The essential amino acids are those...
Role of the nonessential amino acids
Amino acids serve as the fundamental building blocks of proteins. Proteins in turn participate in a multitude of functions and processes, such as digestion of food or repair of injured tissues- all of which are necessary for life. Amino acids are...
Amino Acid in Blood
Amino acids are known to be the building blocks of the body and play a vital role in the construction of proteins which is very essential for bodily functions. However, recent studies have shown that high amount of an amino acid called homocysteine...
Liquid Amino Acids
Protein- builders are very important to the human body. It does the repair and development of growth. Through an assimilation, it showed that the body produces over 50, 000 proteins and 15, 000 enzymes. Not only is it responsible in producing the...
