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).
transÂ·amÂ·iÂ·naÂ·tion. The reaction between an amino acid and an Î±-keto acid through which the amino group is transferred from the former to the latter; in certain cases the reaction may be between an amino acid and an aldehyde (for example, glutamate with glutamate semialdehyde via ornithine transaminase).ransamination (tranzamÂ´inÄÂ´shÉn) , n the reaction between an Î±-ketoacid and an amino acid in which the amino group moves to the Î±-ketoacid, creating a new amino acid and a new ketoacid.
