Lipoproteins
Lipoproteins are an organic compound composed of proteins and
fatty substance found in the body. These fatty substances can be
classified into two categories firstly lipid such as fatty
acids, secondly steroids such as cholesterol. It can also be
called a combination of various proteins in which one of the
components is lipid. They are actually classified onto the basis
of the density and chemical quantities. Generally they perform
the task to transport lipid into bloodstream for further
actions. Lipoproteins are biochemical assembly containing
proteins and lipids and they can be either structural or
catalytic in nature. Literary lipoproteins can be enzymes, ion
pumps, proton pumps or even the mixture of these actions.
Despite the fact that they can't perform any catalytic activity
by themselves still they form the major part of the body as they
take fat around the body.
Broadly there are two types of lipoproteins known as High
Density Lipoproteins and Low Density Lipoproteins. But very few
know about the third one called as Very Low Density
Lipoproteins. High Density Lipoproteins or HDL is known to be
the good cholesterol produced in the body. It is always needed
by the body in order to carry the cholesterol to the liver, as
it removes the extra fat from the arteries and its surrounding
walls. Being the smallest and densest of all it carries maximum
of proteins making it good cholesterol. This produced and
carried protein is known as Apolipoproteins which synthesize the
excess fat and breaks it into smaller pieces. It never allows
fat and Low Density Lipoproteins to settle down in the body and
that too at a particular part. This reduces the risk of heart
and cardiovascular diseases.
Whereas Low Density Lipoproteins or LDL is bad cholesterol
that's excess and can lead to various heart diseases. Its
concentration in and on the arteries is the road to heart attack
and cardio diseases. Being very small and denser in comparison
with HDL it contains maximum of fat and cholesterol instead of
proteins making it threatening fat. It has been witnessed that
it increases at faster rate within the body of obese and
diabetic person as their immune system is not that strong. The
best way to lower down Low Density Lipoproteins is to do
exercise and few body movements as it breaks down the
concentrated fat and transport that to liver for further
metabolism.
So it is in your hands to higher or lowers your lipoproteins as
it is said excess of everything is not good and healthy.
