G proteins are molecules activated by their binding with G protein-coupled receptors (GPCRs).
<h3>What are G proteins?</h3>
G proteins are proteins that act during cellular signaling to transmit information via molecular cascades.
G proteins act by their binding with suitable ligand, where G protein-coupled receptors bind to the G protein and it triggers a molecular cascade.
In conclusion, G proteins are molecules activated by their binding with G protein-coupled receptors (GPCRs).

This client's jaundice can be explained by an obstruction of the common bile duct caused by pancreatic cancer.
<h2>
Jaundice</h2>
Because of elevated bilirubin levels, jaundice, also known as icterus, causes a yellowish or greenish coloring of the skin and sclera. In adults, jaundice is usually a symptom of underlying illnesses such as aberrant heme metabolism, liver malfunction, or biliary-tract obstruction. Jaundice is uncommon in adults, but it is frequent in babies, with an estimated 80% of them experiencing it during their first week of life. Itching, pale feces, and dark urine are the three most prevalent symptoms of jaundice.
In this client's case, the abnormal pancreatic neoplasm has obstructed the common bile duct, which causes the bile to accumulate in the liver and thus rises bilirubin levels in the blood.
