Tyrosine (3 letter code)
Tyrosine is one of the 20 essential amino acids that are used to build proteins in our body
Tyrosine is one of the 20 essential amino acids that are used to build proteins in our body. It is represented by the 3-letter code “Tyr”.
Amino acids are the building blocks of proteins, and they are composed of an amine group (-NH2), a carboxyl group (-COOH), and a side chain or R-group. In the case of tyrosine, the R-group is represented by a benzene ring with a hydroxyl group.
The chemical structure of tyrosine includes an aromatic ring, making it an aromatic amino acid. The hydroxyl group (-OH) on the benzene ring allows tyrosine to form hydrogen bonds and participate in various biochemical reactions.
Tyrosine is a non-polar amino acid, as its R-group is hydrophobic (water-repelling). It is synthesized in our body from another essential amino acid called phenylalanine. Tyrosine plays important roles in various physiological processes, including protein synthesis, neurotransmitter production (such as dopamine and norepinephrine), and thyroid hormone synthesis.
In the genetic code, tyrosine is encoded by two different codons: UAC and UAU. These codons are specific RNA sequences that correspond to the amino acid tyrosine during protein synthesis. The codon UAC is often referred to as the start-codon for tyrosine.
In summary, tyrosine is a 3-letter code represented by “Tyr” and is an essential amino acid. Its structure includes an aromatic benzene ring with a hydroxyl group, and it has various important roles in protein synthesis and biochemical processes in the body.
