All life depends on the source of nitrogen for survival. Humans get their nitrogen from amino acids, which are building blocks for protein. Amino acids are nuts and bolts for all our cellular processes.
Although plants can synthesize all the amino acids needed for their survival, this is not true of humans. Humans make some amino acids, but others come from the foods we eat.
There are 20 amino acids that humans need to achieve cell function. These amino acids are broken down into ten essential amino acids and ten non-essential amino acids.
Essential amino acids are those that are provided by our diet. Essential amino acids include arginine, histidine, isoleucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine.
Inadequate levels of essential amino acids can greatly disrupt the way our bodies work. For example, tyrosine, tryptophan, phenylalanine, and histidine deficiency can lead to neurological problems and depression. Low levels of tryptophan also make us anxious and unable to sleep.
When we don’t have enough methanone in our bodies, we are more prone to allergy symptoms and automatic immunity. Branched amino acids, leucine, isoleucine, and valine provide rehabilitation and energy needs. During hunger, all three are broken down in the liver to supply energy.
Because plants do not contain all the amino acids that humans need to survive (ie, licenses), a strict vegetarian diet is not in our best interests. We need protein from meat, fish, eggs, and milk. A balanced diet prevents our body from breaking down other tissues to replenish the supply of amino acids.
Unnecessary amino acids are those that the body produces internally. Unnecessary amino acids include alanine, aspirin, aspartic acid, cysteine, glutamic acid, glutamine, glycine, proline, serine, and tyrosine. Glucose molecules provide a precursor to carbon skeletons for unnecessary amino acids.
If not enough amino acids are produced, then, the body begins to break down to meet its needs. Glutamine and alanine are broken down in muscles during hunger. Low glutamine levels mean trouble for kidney and intestinal functions.
The presence of essential amino acids guarantees that non-essential amino acids are also present. For example, the essential amino acids cysteine and tyrosine are made from the essential amino acids phenylalanine and methionine. Similarly, the presence of serine means that the body can make glycine.
Now that we know why we need amino acids, how does it work?
A balanced diet is a necessity. It provides us with proteins that provide building blocks for cellular processes. The protein we eat is broken down into peptides and amino acids by hydrolytic enzymes in the pancreas and small intestine. Peptides are chains of amino acids.
The peptides are then broken down in the intestine by further enzymes into the amino acid component called amino peptides and dipeptides. Amino acids are transported from the intestinal lemon to the cytoplasm of cells. From there the amino acids are transported to different parts of the body.
Tissue proteins can also break down amino acids. They then provide energy and are used to make nucleic acids, purines, and pyrimidines that are used to synthesize DNA, the molecules of life. Any amino acid that the body does not use is excreted as urea because too much nitrogen is toxic to our body.
We have found that amino acids are essential for DNA synthesis and provide energy to the body. They are involved in gluconeogenesis and the metabolic process of the citric acid cycle. They also help transport oxygen to the blood. Amino acids are the main components of hemoglobin. The primary function of hemoglobin is to carry oxygen from the blood to different parts of the body. Amino acids also help vitamins to do their job, as well as regulate enzymatic processes and hormonal activity.
Amino acids transmit signals to our brain and other parts of the body and are carriers of information in our body. Lack of these products makes us emotional and tired. Without amino acids, our bodies would not be immune to bacterial and viral infections because proteins make antibodies against these invaders. Waste builds up and we get sick.
Amino acids are important for all mechanisms of life, be it plant, animal or human. A balanced diet is essential for providing essential amino acids so that the unnecessary things that sustain us.
