So what are amino acids? They are organic molecules that come together to form proteins. The coming together of amino acids would yield proteins. That’s why amino acids are very important in the body. Proteins are important for normal cell functions in the body. Some proteins act as antibodies, some act as enzymes while others provide structural support. There are actually hundreds of amino acids that can be found in nature. But just proteins are just made from 20 of these amino acids. And among these 20 there are essential, non-essential, and conditionally essential amino acids. People would commonly ask which of the following is an essential amino acid? Well, you’ll find out in a bit.
Let’s do a bit of an explanation of the different types of amino acids. There are non-essential amino acids. These are produced in the body. So the body can make these amino acids. Essential amino acids, on the other hand, can’t be made by the body. They are usually gotten from food sources. That’s why it’s important to know food sources that are rich in essential amino acids. Conditionally essential amino acids, on the other hand, may be needed in children or when a person is ill. Well, for today we’ll just be concentrating on essential amino acids.
What are Amino Acids?
So amino acids are known to have certain structural properties. They have carbon which is the alpha carbon. They also have a hydrogen atom. Also, there’s a carboxyl group. And then an amino group. And for some, there are certain variable groups or an “R” group. All these make up the different amino acids that we have in our bodies.
All the amino acids have an alpha carbon that’s joined to a hydrogen atom, an amino group, and a carboxyl group. The only thing that differs is the “R” group. Different amino acids have different “R” groups. And this is what determines the difference between the different protein monomers.
Based on the different “R” groups amino acids can be classified into 4 groups. It can either be polar, nonpolar, negatively charged, and positively charged. For the polar amino acids, they have “R” groups that are hydrophilic. This means that the amino acid can dissolve in aqueous solutions. While nonpolar is the opposite of polar. The “R” group is hydrophobic and can’t dissolve in an aqueous solution.
- Nonpolar amino acids are alanine, isoleucine, glycine and leucine, valine, methionine, phenylalanine, tryptophan, and proline.
- Polar amino acids are serine, cysteine, tyrosine, threonine, glutamine, and asparagine.
- Negatively charged amino acids are glutamate and aspartate.
- Positively charged amino acids are arginine, lysine, and histidine.
Which of the following is an essential amino acid?
So it’s true that all amino acids are important for normal bodily functions. There are 11 that can be produced in the body. Those are called the non-essential amino acids. While the remaining 9 are essential amino acids.
The 20 amino acids are lysine, histidine, isoleucine, leucine, threonine, valine, tryptophan, methionine, phenylalanine, arginine, alanine, aspartate, asparagine, cysteine, glutamine, glutamate, proline, glycine, tyrosine, and serine. So which of the following are essential amino acids? They are lysine, histidine, isoleucine, leucine, threonine, valine, tryptophan, methionine, phenylalanine. The nonessential ones are arginine, alanine, aspartate, asparagine, cysteine, glutamine, glutamate, proline, glycine, tyrosine, and serine.
There are food sources that provide you with essential amino acids. And they are eggs, white fish, meat, and soy protein.
The Essential Amino Acids
This amino acid is very important for the growth of muscle tissue. It’s also very important for the repairing of tissue. It’s important for maintaining the myelin sheath. And this is the sheath that protects nerve cells. This ensures that you can get the messages being sent. It also has anti-inflammatory and antioxidant properties. This is also a precursor for the neurotransmitter histamine. And it helps the production of white blood cells and red blood cells in the body.
Also very important for the repair of muscle and the growth of muscle. It’s concentrated in the muscle so it plays a role in muscle metabolism. It also provides fuel for the muscle to work. Also, this amino acid is involved in the formation of a blood clot. And is also vital for the production of hemoglobin.
When it comes to building muscle mass this is one of the most important amino acids. It helps stimulate the synthesis of protein in the body. Also, it helps out with the production of growth hormones and insulin in the body. Insulin helps out with regulating normal blood glucose levels in the body.
This amino acid is very effective in producing hormones and enzymes. It also helps produce antibodies that help fight against foreign bodies in the body. It is also known to have antiviral properties. With research, it has been found out this amino acid is effective against the herpes virus.
This amino acid is involved in many detoxifying processes in the body. It helps protect the body against pollutants and even cell aging. At the same time, it helps the body absorb zinc and selenium a lot better. This amino acid as well is effective for improving the elasticity of the skin. Thus making the skin look younger. And it helps strengthen the nails and hair.
This amino acid is important for the production of another amino acid known as tyrosine. Tyrosine is important for the production of certain neurotransmitters in the body that are essential for the normal functioning of the body. It also helps with the production of melanin.
It’s important for the production of elastin and collagen. And these two are proteins needed for good skin health. Also, this hormone is known to be high in the central nervous system. And it has been linked to alleviating anxiety and depression.
This is a precursor for serotonin. It’s a neurotransmitter that affects sleep, mood, and even pain. Also, this neurotransmitter has been linked to reducing appetite. And that means it could affect weight loss.
This is also very important for the growth and repair of muscle tissues. It helps maintain energy levels. And also helps regulate normal blood glucose levels in the body. It has also been linked to increased physical and mental stamina.
So there you have it. A list of the essential amino acids. And that’s the answer to your question, which of the following is an essential amino acid.
