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).
Alpha-chymotryysin is one of many crystalline enzymes whose properties can he investi-gated on a molecular basis. Its physiological role is the catalysis of the hydrolysis of protein; thus it is a catalyst for the cleavage of peptide or amide bonds.In addition to the cleavage of polymeric amides, it also catalyzes the cleavage of amides of individual amino acids (1).lpha-chymotryysin is one of many crystalline enzymes whose properties can he investi-gated on a molecular basis.
