If you are one of those people who sees cholesterol as a bad substance that resides in fatty food and can cause serious health problems then this post is for you. This organic molecule is much more complex and interesting than we give it credit (and we should give it more credit). From the chemical point of view, cholesterol is a modified steroid – a lipid molecule that is biosynthesized by all animal cells because it is an essential structural component of all animal (but not plant or bacterial) cell membranes and is required to maintain both membrane structural integrity and fluidity. Cholesterol enables the cells to dispense with a cell wall to protect membrane integrity and cell viability, thus allowing them to change shape and move about. In other words, cholesterol – in a certain amount – is absolutely essential for our survival, which is why we think this bizarre molecule deserves our attention. Therefore, we decided to dedicate today´s post to cholesterol. If you want to know what exactly your body needs cholesterol for, how to reduce high cholesterol or what the cholesterol level of an average person is, check out these 25 Things You Need To Know About Cholesterol.
