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).
The AVP gene provides instructions for making a hormone called vasopressin or antidiuretic hormone (ADH). ADH starts out as a larger molecule called a preprohormone, which is cut (cleaved) and modified to produce the active hormone and several related proteins.he major function of ADH is to help control the body's water balance by determining how much water is excreted in urine. Normally, when a person's fluid intake is low or when a lot of fluid is lost (for example, through sweating), the pituitary gland releases more ADH into the bloodstream.
