AIM
The aim of this investigation is to explore the effect of different concentrations of bile salts on the time taken for the lipase enzyme to break down fat.
BILE
Bile is a brownish bitter alkaline fluid produced by the liver and made by the hepatocytes from water, bile salts, bile pigments cholesterol and phospholipids and stored in the gall bladder. Bile is directly connected with digestion. It is released sporadically into the small intestine (duodenum) which is part of the gut in order to help digestion. Bile contains chemicals that break down/emulsify fats by dispersing fat globules into small droplets, therefore increasing the surface area, in turn speeding up the reaction. When fats get to the small intestine they activate the discharge of secretin and cholecystokinin-pancreozymin (CCK-PZ). Secretin encourages bile production, and CCK-PZ promotes the release of bile into the small intestine.
The bile salts help in the breakdown and absorption of fats, while......
