Interesting Facts about (2S)-2-amino-3-methyl-3-sulfanyl-butanoic acid

(2S)-2-amino-3-methyl-3-sulfanyl-butanoic acid, commonly known as methionine, is an essential amino acid that plays a crucial role in various biological processes. Here are some fascinating facts about this compound:

• Protein Building Block: Methionine is one of the 20 natural amino acids that are incorporated into proteins. It is typically the first amino acid in the sequence of proteins synthesized during translation.
• Critical for Growth: As an essential amino acid, methionine must be obtained through diet. It is integral for tissue growth and repair, making it particularly important in periods of rapid growth, such as during childhood and pregnancy.
• Role in Metabolism: Methionine participates in the synthesis of other important compounds, such as cysteine and taurine. It also plays a role in the formation of S-adenosylmethionine (SAMe), a key methyl donor involved in numerous biochemical reactions.
• Antioxidant Properties: Methionine has antioxidant properties, which help protect cells from oxidative damage by neutralizing free radicals. This characteristic is significant in the context of aging and various disease processes.
• Source of Sulfur: As a sulfur-containing amino acid, methionine is a vital source of sulfur for the body, which is essential for the synthesis of various biochemical compounds, including certain vitamins and coenzymes.

In the words of famous biochemist Michael J. Rutter, "Methionine represents a vital intersection between nutrition and metabolism, emphasizing the significance of dietary amino acids in human health." This essential amino acid underscores the intricate relationship between our diet and overall well-being.

Understanding the role and function of methionine highlights the interconnectedness of nutrients in biochemistry and provides insight into dietary planning for optimal health.
