What cell fat droplets do in a cell?
Lipid droplets are organelles that function as lipid storage within cells. They can also be called adiposomes, lipid bodies or oil bodies.
In the human digestive system, Lipase is an enzyme that breaks down fat molecules. While Lipase is able to break down triglycerides (fat) into fatty acids and glycerol, this process occurs slowly. Bile salts break up large fat droplets into smaller droplets, effectively increasing the surface area, which increases the rate at which the fat is able to be broken down by Lipase.
Bile is a natural "soap." It breaks up and surrounds the oil, forming little droplets. The droplets can be assimilated without being digested. So you body doesn't have to break down fats into not-fat parts; it can use the oils as constructed. This is a more efficient way to get fats (oils) into the body.
In the duodenm a secretion called Bile is added. The molecules in bile hold the fat in little droplets ones the mechanical movement has broken the large fat globule into them. Here lipases can act to breakdown the fat molecules containted within the droplets. Most of thie takes place at the end of the duodenum and begining of the jejunum. These are both in the structure called the small intestine.
Bile is a rather clever tool in digestion of fats. Its role is emulsification which means to break down into little droplets. You see fats (oils mostly) do not mix with water as it is hydrophobic. Bile has two parts to it a hydrophilic head (likes ot be in water) and a hydrophobic tail (does no like to be in water). The tails of the molecule stick into the droplets of fat while the heads…
Its gonna get smaller because in fresh milk there is cream at the top and when milk is homogenized it blends together wich makes it smaller. Fat droplets are forced through small openings at high pressure during homogenisation. This makes the droplets smaller, of the same size and evenly distributed in the milk. Because of this the droplets will take much longer to aggregate and float to the top of the milk.
