(N/A) Bile juice is produced by the liver and stored in the gall bladder. It is released into the duodenum to aid in digestion.
The composition of bile juice includes:
$1$. Bile pigments: Bilirubin and biliverdin (breakdown products of hemoglobin).
$2$. Bile salts: Sodium glycocholate and sodium taurocholate,which are essential for the emulsification of fats.
$3$. Cholesterol: $A$ lipid component.
$4$. Phospholipids: Such as lecithin.
$5$. Water and electrolytes: Bile juice does not contain any digestive enzymes.
Function: Bile salts help in the emulsification of fats,which involves breaking down large fat globules into smaller micelles,thereby increasing the surface area for the action of the enzyme lipase.
