Classifications of Amino Acids. However, the classification as essential or nonessential does not actually reflect their importance, as all 20 amino acids are necessary for human health. ... If the side chain contains a carboxylic acid, the amino acids in the acidic-polar classificationare Aspartic Acid and Glutamic Acid

Amino Acids
Amino acids are a crucial, yet basic unit of protein, and they contain an amino group and a carboxylic group. They play an extensive role in gene expression processes, which includes the adjustment of protein functions that facilitate messenger RNA (mRNA) translation (Scot et al., 2006).
In nature, over 700 types of amino acids have been uncovered. Almost all of them are α-amino acids. They have been discovered in: bacteria; fungi; algae; various other plants.
These amino acids are present in bigger molecules as:
• Essential components of peptides and proteins
• Basic structures
- Amines
• Other types of amide
• Acidic structures
- Carboxylic acids; phenols
• Esterified structures
- Ethyl acetate is an example of an ester, as is ethyl ethanoate.
- When carboxylic acids and alcohols are combined, they create an esterified structure, and they lose a molecule of water during when combining.
- The hydrogen on the carboxyl group of acetic acid is replaced with an ethyl group.
• Alkylated structures
- Non-polar side chains (alkyl groups)
- Polar (amides, alcohol - depending on how many side chains they have)
- Leucine is an example of an alkylated structure.
Amino acids also exist in free form. In particular, 20 very important amino acids are crucial for life as they contain peptides and proteins and are known to be the building blocks for all living things. They are contained in living cells where they are used for protein synthesis. These amino acids are controlled by genetics. But not all natural amino acids reside here. In fact, some very unusual amino acids are contained in plant seeds, where they are not crucial to the mature plant. However, they ward off predators and such for protection, giving off toxins or other unpleasant characteristics in order to help certain plant species survive.
As mentioned above, amino acids are imperative for sustaining the health of the human body. They largely promote the:
• Production of hormones
• Structure of muscles
• Human nervous system's healthy functioning
• Health of vital organs
• Normal cellular structure
If amino acids are deficient, then protein synthesis does not occur.
In addition to other positive body functions and growth, without alpha-amino acids, a person may experience fatigue, irritability, hormonal imbalances, and sometimes even depression.
To understand the abbreviations of amino acids, it is important to know why they have been abbreviated in the first place. This is to make them easy to identify and to shorten them in more manageable three-letter systems. Here we'll take a look at the simplest amino acid, glycine. It is depicted as H-Gly-OH, with the «H» and the «OH» being «H2O», which represents the H2O at the time of amino acid condensing in order to form a peptide.

Another way to look at the three-letter abbreviation system is that it captures the amino acid residual state, which comprises proteins and peptides. When this system was introduced, it was done so primarily to save space, rather than simplify amino acid names. It is important to know that, when a one-letter system is used, such as «G» for glycine, which is more commonly used nowadays, it is referring to synthesized peptides from the coded amino acids groups. However, this one-letter system is not to be referenced in other contexts.
