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).
What does my thyroid gland do? The thyroid gland produces hormones which regulate the bodyâs metabolic rate as well as heart and digestive function, muscle control, brain development and bone maintenance.he release of thyroid hormones from the thyroid gland is controlled by thyrotrophin-releasing hormone (TRH) from the hypothalamus in the brain and by thyroid stimulating hormone (TSH) produced by the pituitary gland. This forms part of a feedback loop called the hypothalamic-pituitary-thyroid axis.
