Introduction to Standard Amino Acids
Amino acids are the building blocks of proteins. Proteins are the main component of the human body, accounting for about 50% of the dry weight. They are essential for the structure, function, and regulation of the body’s tissues and organs. The body can make most of the amino acids it needs, but there are eight that it cannot make and must get from food. These are called essential amino acids.
Amino acids are classified according to their chemical structure. There are 20 standard amino acids, which are divided into two categories: essential and non-essential.
Non-essential amino acids can be made by the body.
Essential amino acids cannot be made by the body and must be obtained from food.
The standard amino acids are:
alanine
arginine
asparagine
aspartic acid
cysteine
glutamic acid
glycine
histidine
isoleucine
leucine
lysine
methionine
phenylalanine
proline
serine
threonine
tryptophan
tyrosine
valine
Standard Amino Acids Definition
Standard Amino Acids are the 20 amino acids that are used to create proteins. These amino acids are essential for human life and must be obtained through the diet. Standard amino acids are classified by their chemical structure and include both essential and non-essential amino acids.
Twenty Standard Amino Acids
There are 20 standard amino acids that are used to build proteins in the body. The amino acids are classified as essential or non-essential. Essential amino acids cannot be made in the body and must be obtained from food. Non-essential amino acids can be made in the body. The standard amino acids are:
• Alanine
• Arginine
• Asparagine
• Aspartic acid
• Cysteine
• Glutamic acid
• Glutamine
• Glycine
• Histidine
• Isoleucine
• Leucine
• Lysine
• Methionine
• Phenylalanine
• Proline
• Serine
• Threonine
• Tryptophan
• Tyrosine
• Valine
1. Non-Polar Amino Acid
Non-polar amino acids are those which have a hydrocarbon chain in their side chain. These amino acids are not soluble in water and so they are found in the hydrophobic interior of proteins.
2. Polar Uncharged Amino Acids
Polar uncharged amino acids are amino acids that have a net charge of zero. These amino acids are polar because they have a positive and negative side, and they are uncharged because the positive and negative sides cancel each other out. Some of the most common polar uncharged amino acids are asparagine and glutamine.
3. Acidic Amino Acids
Amino acids that are acidic are glutamate, aspartate, and histidine. Glutamate and aspartate are the most important of the acidic amino acids in the brain. Glutamate is the main excitatory neurotransmitter in the brain and aspartate is a major Glutamate receptor agonist. Histidine is a precursor of histamine, which is important in learning and memory.
4. Basic Amino Acids
Amino acids are the building blocks of proteins. There are 20 different amino acids that are used to build proteins. Nine of these amino acids are essential, meaning that the body cannot produce them and they must be obtained from food. The other 11 amino acids can be produced by the body.
The nine essential amino acids are:
Histidine
Isoleucine
Leucine
Lysine
Methionine
Phenylalanine
Threonine
Tryptophan
Valine
These modifications play an important role in the stability and function of collagen proteins.
Revising the concept of Standard Amino Acids
Standard amino acids are those that are encoded by the genetic code and are used to make proteins. The 20 standard amino acids are:
alanine, arginine, asparagine, aspartate, cysteine, cystine, glutamate, glutamine, glycine, histidine, isoleucine, leucine, lysine, methionine, phenylalanine, proline, serine, threonine, tryptophan, tyrosine, valine.
Importance of Learning Standard Amino Acids
Amino acids are the building blocks of proteins, which are essential for the body to grow and function properly. There are a total of 20 standard amino acids, and they play important roles in a variety of bodily processes.
Some of the key functions of amino acids include:
Building and repairing tissues
Making enzymes and hormones
Serving as energy sources
Carrying nutrients around the body
Amino acids are essential for human health, and not getting enough of them can lead to a variety of health problems. That’s why it’s important for everyone to know about the standard amino acids and how to get them from food sources.
