Biomedical importance of cholestrol

INTRODUCTION

This presentation is a brief knowledge about cholesterol its importance and its role in our bodies along with respective diseases.
CHOLESTROL
A compound of the sterol type found in most body tissues, including the blood and the nerves. Cholesterol and its derivatives are important constituents of cell membranes and precursors of other steroid compounds

OCCURENCE
Endogenous: Cholesterol is naturally found in our bodies.  75% of your body’s requirements are fulfilled by the endogenous cholesterol produced in the liver.
Exogenous: The cholesterol we get from food. Exogenous cholesterol is obtained from animal products, and this source of cholesterol accounts for about 25% of the body’s cholesterol needs.

CLASSIFICATION OF CHOLESTROL
Two types of cholesterol:

HDL
“Good” Cholesterol
High levels of HDL have been found to lower risk of heart attack
Risk of heart disease increases when there are lower levels of HDL.
“Help remove cholesterol from artery walls and transport it to the liver for elimination from the body”
LDL
Bad cholesterol that can build up in the arteries.
High levels of LDL can increase risk of heart disease.
Composed mainly of cholesterol and a few proteins.
“Primarily responsible for depositing cholesterol within arteries”
BIOMEDICAL IMPORTANCE
Hypercholesterolemia
Atherosclerosis
Heart diseases
Cardiac attack/stroke
Death

HYPERCHOLESTEROLEMIA
Hypercholesterolemia
is a condition
characterized by
very high levels of
cholesterol in the
blood. 
ATHEROSCLEROSIS
Atherosclerosis is a disease in which plaque builds up inside your arteries. Arteries are blood vessels that carry oxygen-rich blood to your heart and other parts of your body.

HEART DISEASES
the blood carries oxygen to our heart, atherosclerosis reduces the amount of blood flowing to our heart. If blood stops flowing to the heart because of a blockage in the arteries, a heart attack occurs.
CARDIAC ATTACK
When coronary artery of heart gets blocked by cholesterol deposition heart doesn’t get the blood supply it needs so cardiac attack occurs due to myocardial infarction.

STROKE
 Plaque buildup can also keep your brain from getting enough blood and oxygen. If a clot completely blocks an artery feeding your brain, you have a stroke.


WHAT TO EAT???
Grains (Fiber)
Any source of oatmeal,
granola or nuts can be
considered a form of fiber.


Oils (Fats)
Unsaturated fats used in
moderation like: olive oil, canola oil or soybean oil


Cont…
Fruits
Any form of fruit or
vegetable Oranges
and raspberries

Meats
Skinless poultry
and lean meats
