L-Serine is a non-essential amino acid, which means that it is required for the human body to properly function, but does not need to come from an outside source. Instead, it is typically produced within the body from metabolites, such as glycine. Serine, also known as Ser, is a proteinogenic amino acid. This means it is one of the 22 amino acids that are part of the standard human genetic code. The word proteinogenic is derived from the Latin for 'protein-building.' In 1865, this amino acid was first isolated from protein contained in silk. Silk has a large concentration of it, and the amino acid was named using the Latin word sericum, which means silk. By 1902, the the chemical structure of serine had been determined. The main uses of serine in the human body are to assist in the function of the central nervous system (CNS), as well as with general brain operation. It is present in the myelin sheaths that cover the nerves located in the brain. Without sufficient serine, these sheaths become thin or disappear altogether, leading to an inability for the nerves to transmit messages to other parts of the body.
