Most of the girls may think that oil will make us grow larger in size, increases in weight and become fatter. Thus, we are trying to avoid fats intake from food, especially the people who is on-diet because we know that: Fats-will-make-us-FAT!!!!
However, fat will make the food delicious most of the time. For example, cakes, pizza, and fried foods are delicious but high in fats content, right?
Who doesn't like fried chicken, cheesecakes and chocolate?
As the knowledge we get from both biology and chemistry classes, fats are high in energy content. Based on the information get from the internet, one gram of fat can provides 9 calories indeed to provide 37.62 kJ of energy whereas both of protein and carbohydrate can only provide 4 calories per gram!
For sure, the excess supply of energy (food) will be stored in our body, in different form, most probably is in the form of fats.
While, the people that concern on their health will avoid to takes in too much oil, especially the food that contained LDL (Low-density-lipoprotein), saturated fats and trans-fat.
Do you know what is the different between LDL and HDL (High density lipoprotein)?
Both of them are lipoprotein (lipids and protein bound together) that carry fats in the blood stream. Many enzymes, transporters, structural proteins, antigens, adhesins and toxins are building up by lipoproteins.
Besides, we always call the LDL as bad cholesterol lipoprotein and call the HDL good cholesterol lipoprotein because LDL brings cholesterol from the liver to body cells while HDL transport cholesterol in the opposite way, that is bring it back to the liver from the body cells. The trans-fat is said to be a bad thing is just because it transfer the HDL to LDL.
I still remember that my previous biology lecturer told us that:” I don’t eat Oreo, because Oreo contains so many trans-fats….”
As what we learn during secondary school time, fats is organic compound that generally insoluble in water. It is the ester form when a pure carboxylic acid reacts with glacial organic alcohol. Is that the reason of some essential oil (most of them is from flower) have a good smell?
Such as rose, that has the fantastic smell.
Fat is tri-esters of glycerol and fatty acids. We called it 'fats' when it is in the solid state in room temperature, and 'oil' when it is in the liquid form. While, we also called the grease as oil!
When a carbon atom binds to the maximum number of hydrogen atoms, we called it as the saturated fatty acids because it is unable to bind and react with other atoms anymore. In the other hand, if there is still any double bond or single bond in the carbon atom, we will call it as an unsaturated fatty acid. It is called monounsaturated acid if there is only 1 double bond in the carbon compound while it would be polyunsaturated acids if the compound contains more than 1 double bond. All of these fats differ in their energy content and melting point. Since an unsaturated fat contains fewer carbon-hydrogen bonds than a saturated fat with the same number of carbon atoms, unsaturated fats will yield slightly less energy during metabolism than saturated fats with the same number of carbon atoms. Saturated fats can stack themselves in a closely packed arrangement, so they can freeze easily and are in solid at room temperature. But the rigid double bond in an unsaturated fat fundamentally changes the chemistry of the fat.
We can found the lipids everywhere in our life. For example, all of the animasl have fats in their body as the form of lard, butter, blubber, ghee and fish oil, but most of the animal oils are saturated fats, which means that it has only single bond in their molecular structure. As what we stated at above, saturated fats would not react with other chemical easily as it has only single bond. That is why most of the nutritionists recommend us to intake unsaturated fats compare to saturated fats, because only unsaturated fats can form chemical reaction with other substances in our body. Luckily we still can gain the unsaturated fats from delicious food, such as sesame, vegetable, beans, nuts and the olive oil that normally added into salads.
And some more, fats are very important for the absorption, digestion and transportation of fat soluble vitamins A, D, E and K! They cannot be received by our body cells if lipid is absent…
Did you realize that girls’ waterproof cosmetics can only be removed by make-up remover that contains the oil?
It is that much useful for us actually!
