høyaffinitetsystemene
Høyaffinitetsystemene are a group of high-affinity transport systems found in the human body, responsible for the uptake of essential nutrients and other substances into cells. These systems are characterized by their high specificity and rapid transport rates, enabling efficient uptake of substrates despite their low extracellular concentrations. The most well-known høyaffinitetsystemene include the glucose transporter (GLUT) family, which facilitates the transport of glucose into cells, and the amino acid transporter (AAT) family, which transports essential amino acids.
The GLUT family consists of several isoforms, each with distinct tissue distribution and regulatory properties. GLUT1
The AAT family includes various subtypes that transport different amino acids. For example, LAT1 (L-type amino
Høyaffinitetsystemene play crucial roles in maintaining cellular homeostasis and energy balance. They are essential for the
