Cholesterol is theoretically called as lipids or fats. It looks like a waxy powder which is similar to candle wax shavings. It is pale yellow in color. All animals require cholesterol to survive. Lipids supplies chemical energy as fuel for the cells that construct our body. Also it is responsible for the protective shell or covering of cells. It is also necessary for digestion and absorption of nutrients from food.
Cholesterol is important for our sex hormones, testosterone and estrogen, and for vitamin D. Cholesterol is so important that our body controls it so closely that if you did not consume enough dietary cholesterol, your body would produce all it requirements on its own. Your liver has the capability to convert fats, sugars and proteins into cholesterol for its requirements.
Dissimilar sorts of Lipoproteins.
Your bloodstream is the medium which carries cholesterol and other lipids to each cell in the body. Because lipids and blood don't easily mix properly, the body knows to wrap protein around cholesterol particles making it easy to flow through the bloodstream. This is where the name lipoprotein gets its name. Your bloodstream carries many dissimilar sizes of lipoproteins which are grouped depending on the density or fat composition. Additional fat equals lower density. Less fat and higher protein means higher density. There are in fact 4 different fat containing particles in the blood. HDL or high density lipoproteins have the less total of fat (and triglycerides) and the most protein. The largest and least dense is somewhat called chylomicrons that contain the most fat; specially triglycerides. The other 2 are LDL or low density lipoproteins and VLDL or very low density lipoproteins. Most of the fat from our food and the non-cholesterol fat in our bloodstream is triglycerides. Triglycerides are build of 3 fatty acids and glycerol, an alcohol. Triglycerides are vital for our health and supplies a large amount of the energy our tissues require, but too much of a good thing, similar to cholesterol, can be hazardous to your circulatory health.
How LDL is created
Because triglycerides are removed from VLDL and chylomicrons, they become smaller and denser. Ultimately all that leftover is the protein and cholesterol and a minute amount of triglyceride. The liver cleans out the chylomicron and reuses any remnants unlike VLDL which even after it has lost its triglyceride components, continues to circulate. VLDL continues to alter and ultimately results as LDL particles. LDL carries the most of our cholesterol. Practically all cells in the body can utilize LDL for their energy requirements. Though there is normally more LDL in the bloodstream than is needed and the liver should clear the excess from the blood. It might utilize it for more bile acids for digestion or as new lipoproteins. If the liver cannot keep up with the excess LDL, it results in being deposited in places it does not belong.
HDL, the Savior
High density lipoproteins are recognize as the "good" cholesterol and for proper reasons. HDL is also made in the liver and intestines but it is quite dissimilar than LDL. There is a maximum concentration of protein and not much fat in HDL. The two primary roles of HDL are to supply chylomicrons and VLD the protein component that allows the liver to know they need to have their fat removed. HDLs also act as scavengers and collect excess cholesterol from blood vessel linings as well as other locations to be transported to the liver to be disposed of.
