This information is used to determine the density of the air entering the combustion chamber (in conjunction with the IAT (Intake Air temperature) sensor), which is used when calculating the proper air/fuel mixture for the engine, especially at WOT since the system is not in closed-loop at this time.
The TTR gene provides instructions for producing a protein called transthyretin. This protein transports vitamin A (retinol) and a hormone called thyroxine throughout the body. To transport thyroxine, four transthyretin proteins must be attached (bound) to each other to form a four-protein unit (tetramer).
1- Transamination. Transamination means transfer of amino group from-amino acid to-keto acid with formation of a new-amino acid and a new-keto acid. The liver is the main site for transamination. All amino acids can be transaminated except lysine, threonine, proline and hydroxy proline.
