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).
transamination the process by which amino groups are transferred from one AMINO ACID to form another, using a keto acid as an intermediary. The mechanism takes place in the liver, and is important in the breakdown of excess amino acids to form keto acids and in the formation of new amino acids (perhaps not available in the diet) from keto acids.
