Bile acids are essential molecules the liver produces that play a critical role in digestion. They help us absorb fat-soluble vitamins and cholesterol from our food. However, bile acids can become a ...

Bile acids are amphipathic steroid molecules synthesised from cholesterol in the liver and secreted into the intestine where they facilitate lipid digestion and absorption. Primary bile acids are ...

(A) The classic bile acid synthesis pathway: cholesterol 7α-hydroxylase (CYP7A1) converts cholesterol to 7α-hydroxycholesterol (7α-HOC). The sterol 12α-hydroxylase (CYP8B1) converts the intermediate ...

Many liver diseases share a common characteristic: fibrosis, the progressive accumulation of scarring in the liver tissue. Those scars—the liver's response to persistent injuries or attacks—can ...

Bile acids are essential signaling molecules derived from cholesterol metabolism in the liver and are crucial for the digestion and absorption of fats. These molecules undergo further modification in ...

Caloric restriction may help longevity—but comes with tradeoffs. A molecule called LCA might offer the upside, without the ...

Synthesized in the liver, bile acids play diverse roles in digestion and metabolism. However, when their processes are disrupted, disease can occur. Scientists seek advanced technologies to better ...

Over the years, researchers have amassed strong evidence that caloric restriction can extend lab animals’ lives. Unfortunately, extending those benefits to humans has proved difficult, in part because ...
