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).
Function. Thyroid peroxidase is a type of enzyme produced in the thyroid. This enzyme plays a vital role in helping the thyroid gland produce hormones, specifically triiodothyronine (T3) and thyroxine (T4) hormones.ormones are released by the thyroid that help to that certain bodily functions--such as blood pressure, metabolism and heart functions-- are working properly. Thyroid peroxidase (TPO) is an antibody that can help or disrupt the production of hormones, depending on their working levels.
