8 Questions
What is the primary result of deamination of amino acids?
Ammonia (NH3)
Which vitamin coenzyme is required for transamination reactions?
Vitamin B6
What is the outcome of condensation between two amino acids?
Formation of a dipeptide
What can keto acids resulting from deamination be used for?
Energy production
What are the two products resulting from deamination of amino acids?
Ammonia (NH3) and carbon structure without amino group
What are the two products of deamination and what can they be used for?
The two products of deamination are ammonia (NH3) and a keto acid. Ammonia can be toxic and needs to be converted to urea in the liver for excretion. The keto acid can enter metabolic pathways for energy production, glucose production, or the synthesis of molecules like ketones, cholesterol, or fat.
What is the role of vitamin B6 in transamination reactions, and how does it contribute to the formation of new amino acids?
Vitamin B6 acts as a coenzyme in transamination reactions, facilitating the transfer of amino groups from an amino acid to a keto acid. This transfer results in the formation of a new nonessential amino acid and a new keto acid.
Describe the process of condensation between two amino acids and the resulting molecule. What are the implications of this process in protein synthesis?
Condensation involves the joining of an OH group from the acid end of one amino acid and an H atom from the amino group of another, to form a molecule of water. This forms a dipeptide, which is a building block of proteins. The repeated condensation of amino acids forms polypeptide chains, which ultimately contribute to the structure and function of proteins.
Learn about the deamination process in metabolism, where amino acids are broken down and stripped of their nitrogen-containing amino groups, resulting in the production of ammonia and keto acids. Explore how keto acids may enter various metabolic pathways for energy production or the synthesis of glucose, ketones, cholesterol, or fat.
