Amino acids are, in fact, the building blocks of proteins. They are important for crucial processes such as the cell building and synthesis of hormones and neurotransmitters.

Amino acids are used to treat various diseases. Parkinson’s disease is treated through L-dihydroxyphenylalanine amino acid, while Glutamine is used to treat liver diseases.

Glycine is the smallest amino acid. It does not form stereoisomers as it does not have a hydrogen atom as a side chain.

The four major categories into which amino acids have been divided are essential amino acids, non-essential amino acids, free amino acids, and post-translational modified amino acids. Free amino acids are also known as non-proteinogenic amino acids.

20 amino acids are responsible for the proteins made up in our body, though there are around 500 known amino acids.

L-Histidine is a proteinogenic essential amino acid and is important for infant growth. It is mainly found in fish, chicken, pork, and cheese.

The 20 amino acids in our body are vital for different functions. For instance, Glutamine is required for managing ammonia levels in our body.

There are four elements in each molecule of amino acid. The central carbon atom present in each amino acid molecule is known as the α-carbon atom.

Four key elements form an amino acid. These four elements are carbon, hydrogen, oxygen, and nitrogen. They are the building blocks of proteins in our body.

Essential amino acids cannot be synthesized in our body, hence the name essential. We need to take these amino acids through food.
