Fat is a body consisting of:
1. Fatty acid
2. Triglycerida
3. Cholesterol
4. Posfolipid
5. Glycolipid
Each component has different functions for example:
1. As a source of energy
2. As a cushion against impact.
3. As isolataor to heat
Cholesterol
The function of cholesterol in the body include:
1. Is a substance essential for the body’s cell membranes
2. Is the main ingredient for the formation of bile salts that are needed for food digestion
3. Is the raw material to form a steroid hormone, eg progesterone and estrogen in women, testosterone in men, corticosteroids, and others.
Foods that contain cholesterol include: fried-fried, meat, brain, viscera (intestine, liver, kidneys, lungs, heart), egg yolks, nuts, and others.
Lipoprotein
Fat in the body is transported from one place to another, because fat is not soluble in water, then to transport the fat needed a tool carrier, namely apo-protein, a type of protein.
Apo-protein with the fat that he brought to form a bond, called lipoproteins.
Cholesterol Esters
Created in and comes from the heart and blood chlolesterol, a small part is made in the pancreas and intestinal mucous membrane.
Total chlolesterol = Chlolesterol Esther chlolesterol free. 65-75% of the total content of ester cholesterol chlolesterol, these levels increase in age increased. Esther chlolesterol follow the ups and downs of the total chlolesterol. The liver is an important place in the formation of chlolesterol, esters chlolesterol and excretion into the bile duct.
Phospholipid
He is the fat-containing compound that includes phosphate group of this group are: Lecithin, cephalin, sphingosin, and sphingomyelin. Approximately half of the plasma phospholipid is lecithin. Plasma phospholipid levels are usually higher rises in conjunction with elevated levels of plasma chlolesterol. The normal for adults in a state of fasting between 5-12 mg / 100 ml as a P or 125-130 mg / 100 ml as lecithin. These levels seem higher in the elderly.
