C for Cholesterol

This is the third in the series of 26 posts this month, one post a day, barring four Sundays, each on a theme corresponding to a letter of the English alphabet. The theme this year is "Chemicals in our life", spurred by my interest in chemistry.

I doubt if there is anyone who hasn't heard of or got worried about this chemical compound that is often characterised as a villain.

Cholesterol has a bad reputation because its excess in our body is associated with heart ailments.

However, it is an important chemical compound for a healthy body. 

It is found in blood and tissues, and its chemical formula is C27H46O.

It comes from two sources: our liver and our diet. 

Our liver produces all the cholesterol we need for various functions in our body, such as making hormones (like testosterone and oestrogen), vitamin D and fat-dissolving bile acids. 

Cholesterol in our body also comes from the foods we eat, especially animal products such as meat, poultry, dairy and eggs. 

These foods contain what is called dietary cholesterol, which is absorbed by our intestines and transported to our liver.

Cholesterol is carried by special proteins called lipoproteins in order to travel in our blood. 

There are different types of lipoproteins, each with a different function and composition. 

The main ones are:

Low-density lipoprotein (LDL): This is the so-called "bad" cholesterol because it carries cholesterol from the liver to the cells and tissues that need it. However, if there is too much LDL cholesterol in the blood, it can get deposited on the walls of the arteries and form plaques. These plaques can narrow the arteries and reduce blood flow, increasing the risk of heart disease and stroke.

High-density lipoprotein (HDL): This is the so-called "good" cholesterol because it carries excess cholesterol from the cells and tissues back to the liver for disposal. HDL cholesterol helps to prevent plaque formation and protect against heart disease and stroke.

The level of cholesterol in our blood is influenced by many factors, such as our genes, our diet, our physical activity, our weight, our smoking status, our alcohol consumption and some medications. 

A blood test can measure the amount of total cholesterol, LDL cholesterol and HDL cholesterol. The results can help us assess our risk of developing heart disease and stroke.

    1. Here too, insurance does play a role, but very often, it's left to the discretion of the patient.

  9. Correctly said, cholesterol is made by the liver and we can consume it through animal products. That is the reason it's laughable when there is cholesterol free rice bran oil available in the market.
