TransaminationTransamination, taken literally, means the transfer of an amino group from one molecule to another. In many organisms, this process is used both to synthesize and to degrade amino acids. One of the primary cellular benefits of the reaction is that it allows the transfer of an amino group without the formation of ammonia, which is a toxic byproduct. In humans, transaminationtransaminationtransamination occurs primarily in the liver, and is also known as aminotransfer.
Transamination is a biochemical reaction where an amino group is transferred from an amino acid to a keto acid, forming a new amino acid and keto acid. This process usually occurs in the liver and other tissues.

In transamination the amino group of an amino acid is?
transferred to a keto acid
What is the process in which a amino group is combined with a keto acid to form an amino acid?
Transamination
The process by which amino groups -NH2 are removed from proteins is called?
Deamination is the process by which amino groups are removed from proteins. This process typically occurs in the liver during the metabolism of proteins.
Is sunlight required for the synthesis of amino acids?
Sunlight is not required for the direct synthesis of amino acids in most organisms. Amino acids are typically synthesized through processes like the transamination of metabolic intermediates or the breakdown of proteins. However, sunlight is crucial for photosynthetic organisms like plants, which use sunlight to convert carbon dioxide and water into glucose, which can then be used in amino acid synthesis.
What happens to amino acids inside the liver?
They are broken down into urea then carried via blood to the kidneys and the excreted as urine
Why lysine and threonin do not undergo transamination?
Lysine and threonine do not undergo transamination because they do not possess the alpha-amino group that is required for the transamination process to occur. Transamination involves the transfer of an amino group from an amino acid to an alpha-keto acid, forming a new amino acid. Since lysine and threonine lack the necessary amino group, they cannot participate in transamination reactions.
In transamination the amino group of an amino acid is?
transferred to a keto acid
What alpha-keto acid produce when alanine undergoes transamination?
Pyruvate
What type of reaction is aspartic acid plus α-ketoglutaric acid equals glutamic acid plus oxaloacetic acid?
This reaction is a transamination reaction, where the amino group from aspartic acid is transferred to α-ketoglutaric acid to form glutamic acid and oxaloacetic acid. Transamination reactions are important for amino acid metabolism and synthesis.
Metabolic importance of transamination reactions?
Transamination reactions are important for converting one amino acid into another by transferring an amino group. This process is crucial for amino acid metabolism, as it allows for the synthesis of non-essential amino acids and the breakdown of excess amino acids. Transamination also plays a key role in the urea cycle, helping to eliminate nitrogen waste from the body.
What is the process in which a amino group is combined with a keto acid to form an amino acid?
Transamination
Vitamin B6 is a coenzyme for PLP which plays a role in the process of making nonessential amino acids. This process is termed .?
Transamination is the process in which vitamin B6 is a coenzyme for PLP. PLP does play a role in the process of making nonessential amino acids during transamination.
Vitamin B6 is a coenzyme for PLP which plays a role in the process of making nonessential amino acids This process is termed?
Transamination is the process in which vitamin B6 is a coenzyme for PLP. PLP does play a role in the process of making nonessential amino acids during transamination.
Is deamination the process of transferring the amine group from one amino acid to another?
No, deamination is the removal of an amine group from an amino acid, resulting in the production of ammonia and a keto acid. This process is important in amino acid catabolism.
What is it called When a cell forms an amino acid by adding an amine group derived from ammonia to a precursor metabolite?
This process is called transamination. It involves transferring an amino group from an amino acid to a keto acid to form a new amino acid and a new keto acid.
What is the vitamin that is converted to the coenzyme PLP which is active in amino acid metabolism?
The vitamin that is converted to the coenzyme PLP (pyridoxal phosphate) is vitamin B6. PLP is a crucial coenzyme involved in the metabolism of amino acids, especially in the transamination process where amino groups are transferred between amino acids.
The process by which amino groups -NH2 are removed from proteins is called?
Deamination is the process by which amino groups are removed from proteins. This process typically occurs in the liver during the metabolism of proteins.
