From the question they given us to identify the, we have to identify how does the fat digestion to be occurs and also we have to know how does this fat is going to be converted into lipoprotein.
00:21
So, a fat digestion is going to be involved in the mouth where there is no fat digestion to be taken place because there is a lack of enzymes to break off the fat but the food is going to be broken down in the mouth after that it reaches the stomach.
00:53
In the stomach a gastric lipase is found at the lesser amount therefore small amount of fat digestion that is fat broken down is going to be taken place due to the lipase activity it is going to be small in amount because of the ph.
01:22
A ph of a lipase enzyme must be at basic but here in the stomach it is going to be acidic therefore the action of gastric lipase is going to be decreased.
01:32
Then it reaches a time which is going to reach up the small intestine.
01:40
In the small intestine which consists of a lipase enzyme along with the bile salts.
01:53
In the presence of bile salts and bile acids a lipase can act at the increased ph which makes it to perform along with the bicarbonate which makes it to provide a increased ph.
02:08
When the ph is going to be increased the lipase activity is going to be increased.
02:13
Due to the increased activity causes the process of emulsification to be occurs.
02:22
A process of emulsification is very important in breaking down the lipids.
02:32
Therefore the lipids are going to be broken down into triazylglycerol and fatty acids.
02:47
If the lipids are going to be at the larger chain it can be converted into monazylglycerol or it can be converted into glycerol.
03:02
Therefore these are the three components to be possible during the lipid breakdown.
03:11
In general all of them can produce the fatty acid either along a chain or the smaller chain.
03:18
Therefore these lipids are found to be in the small intestine.
03:23
In the intestine only the absorption of nutrients or simpler molecules to be taken place which can be entered into the blood.
03:37
The absorption is going to be taken place by the intestine with the help of villi.
03:46
Where the villi consists of lacteals, these lacteals are going to absorb the simpler fat molecules in the case of lipoprotein.
04:02
It is going to absorb the lipids as fatty acids and triazylglycerides.
04:18
Where either by this or it may undergoes packing.
04:24
Packaging is going to be taken place in the intestine.
04:29
As the packaging involves these fatty acids are going to be packed off along with the little amount of cholesterol which is not going to be broken down and higher amount of protein.
04:54
Due to this cholesterol, protein and fatty acids which forms a lipoprotein.
05:00
These lipoproteins are going to be enters into the lymphatic system by absorption with lacteals...
