Amino acids are the “building blocks” of the body. They play a vital role both as intermediates in metabolism as well as constructing mass of proteins. They are the basic structural unit of proteins. They do not only build cells and repairs tissues, they also form antibodies that fight bacteria and viruses. Amino acids are part of the enzyme and hormonal system and they build nucleoproteins which are RNA and DNA. They also carry oxygen throughout the body and contribute in muscle activity.
When protein is broken down through digestion, the results are the twenty known amino acids. Eight of these amino acids are essential which cannot be manufactured by the body, while the rest are non-essential and can be manufactured by the body with the proper nutrition.
The eight essential amino acids are:
Isoleucine and Leucine are the amino acids that provide the components for manufacturing of other essential biochemical components in the body, some of which help you to be more alert, used for the production of energy, and serve as stimulants to the upper brain.
Lycine is the amino acid that ensures the adequate absorption of calcium and helps form collagen. This amino acid also aids in the production of antibodies, enzymes, and hormones.
Metheonine is the main supplier of sulfur in the body which prevents disorders of skin, hair and nails. It helps to lower cholesterol levels by increasing the liver’s production of lecithin and it also protects the kidneys and reduces liver fat. This amino acid influences hair follicles and promotes hair growth; it also regulates the formation of ammonia.
Phenylalaine is an amino acid that is used by the brain to produce Norepinephrine which is a chemical that sends out signals between nerve cells and the brain keeping you awake and alert. It also reduces hunger pains and functions as an anti-depressant helping improve memory.
Threonine helps the digestive and intestinal tracts to function more smoothly. It also assists in the assimilation and metabolism of the body. It is an important element of collagen, enamel protein, and Elastin. It also helps prevent fat build up in the liver.
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.
Valine helps in the promotion of muscle coordination, energy, and calm emotions.
Serine is a storeroom source of glucose by the liver and muscles. It helps strengthen the immune system by providing antibodies and produces fatty acids cover around nerve fibers.
The body can produce ten out of the twenty amino acids. The other amino acids must be supplied in the food and failure to attain enough of even one of the ten essential amino acids, those that can’t be produced by the body, results in the ruin of the body’s proteins. Amino acids are not like fats that can be stored by the body for later use, the body does not store excess amino acids and so amino acids must be in the food every day.
Types of Amino Acids
A reputable addendum in connection with nutrition satisfies a diet that benefits in sustaining human beings. It forms the muscles that enable one to build in a single day sans the dilemmas of excess fats and cholesterols without straining the digestion system.
The essential building blocks of protein can only be obtained through foods such as fish, poultry, vegetables and other sources. It can also be taken from supplements that come in several types of amino acids. There are those that range from single or combination of free form, peptide bonded or branched chain.
Comprising L-leucine, L-isoleucine and L-valine, branched- chain are contained in proteins of all life forms. This is one of the types of amino acids wherein its dietary sources are mainly obtained from meats and vegetables.
Better known as BCAA’s or branched- chain amino acids, it was created by some neurological research community. There was then a pilot study that designated that amyotrophic lateral sclerosis (ALS) patients demonstrated improvement when given big doses of BCAA’s. It was then concluded that branched- chain amino acids may safeguard against nueronal damage from nueroexcitatory neurotransmitter glutamate. However, most of the follow- ups came out negative and even indicated that it can increase mortality with those who have ALS.
It sometimes used in parental and enteral feedings in the management of hepatic encephalopathy. It is most of the time utilized in the nursing of major burns and severe trauma because of its possible anticatabolic action.
Referring to certain dipetides that are utilized in total parental nutrition (TPN), peptide bonded amino acids are delivery forms of L- glutamine. This is one of the types of amino acids where it also indicates to those that are found in some supplements specifically those marketed as fitness products. L- glutamine in PBAA’s is an ordinary kind featured in metabolic stress conditions such as infection, cancer, trauma, sepsis and burns. The response to those states is characterized by catabolism balance and negative nitrogen. With those, L- glutamine is normally produced mainly in the skeletal muscles in ample quantities to complete physiological requirements. L- glutamine then becomes an essential protein block- builder and must be provided to the body to avoid breakdown of muscle tissues, immune dysfunction and compromise of gut mucosal barrier function.
One of the types of amino acids that are not bound to any other, free- form refers to the facts that they are independent from one another. Studies showed that there have been plenty of companies that have advertised FFAA’s are the purest active source of protein block- builders that can be purchased in the market. This is however, not true at all instances.
Free- form amino acids are also not immediately absorbed in the small intestines as compared to branded- chain and peptide- bonded. It should only be reserved for use in activities such as workout.
