Cholesterol!


Today as I said yesterday I am going to talk about the cholesterol:
Cholesterol is a lipid found in the cell membranes of all tissues, and it is transported in the blood of all animals.
Most of the cholesterol in the body is synthesized by the body and some has dietary origin.
Cholesterol is insoluble in blood, but is transported in the circulatory system to differents lipoproteins:
(LDL) low-density lipoprotein
(HDL)
high-density lipoprotein
They carry cholesterol from and to the liver, respectively.
In some occasion the cholesterol gets hooked up in the walls of the veins, and obstructs them, the blood cannot circulate and produce different diseases of heart.
On the one hand the lipoprotein, HDL, is termed “bad cholesterol” because contributes in this process, on the other hand, LDL is termed “good cholesterol” because offer a degree of protection.
Abnormally high cholesterol levels (
hypercholesterolemia) and abnormal proportions of LDL and HDL are associated with cardiovascular disease.
This problem can be resolved with exercise, a healthy diet, and sometimes medication.
So, you know, it’s really important take care of yourself.
