Hello! I was wondering why is it that it is safe to eat olive oil, corn oil, canola oil, etc. but not diesel oil or something like that. What is the reason in chemical structural sense?

I've struggled with this answer since I'm not a biologist or biochemist. Perhaps another tutor will add something to my post. Corn oil and olive oil are processed to rid them of toxic materials AND they are much much heavier (more dense and more viscous) than diesel oil or diesel fuel. When I think of diesel fuel I think of something like kerosene. No one in their right mind would drink kerosene. The biodiesel fuels are processed, also, BUT they are distillates of crude oil that comes off at much lower temperatures. For example, the boiling point of kerosene is about 150 C while that of soy oil used for cooking is about 300 and most other oils (corn oil and olive oil) are higher than that. So why don't we drink kerosene or gasoline? They are mixtures of a boiling range that contains hydrocarbons, benzene, xylenes, etc that are known to be carcinogenic. Ingested as a liquid I think they are such non-polar compounds that the human body simply can't digest them. They damage the intestinal tract, the lungs, the kidneys and anything else they come in contact with. Cooking oils, on the other hand, are much higher molar mass, they don't have nearly the extraction possibility of the lower boiling point gasoline/kerosene, they react slower, and the body can handle them as it does any food. I hope this helps. If you want more information, you may want to go to www.google.com and type in key words such as toxicity gasoline, edible oils, etc. To repeat myself, perhaps another tutor will care to add his/her musings.

Hello! The reason why oils like olive oil, corn oil, canola oil, etc. are safe to eat while diesel oil is not can be explained in terms of their chemical structures.

Olive oil, corn oil, canola oil, and similar cooking oils are derived from plant sources. They are composed predominantly of triglycerides, which are molecules made up of three fatty acid chains attached to a glycerol backbone. These oils are typically classified as unsaturated fats, which means they contain primarily monounsaturated or polyunsaturated fatty acids.

On the other hand, diesel oil is a type of fuel typically derived from petroleum, which is a complex mixture of hydrocarbons. Diesel oil is composed mainly of long-chain alkanes, which are saturated hydrocarbons. The chemical structure of diesel oil consists of a linear chain of carbon atoms surrounded by hydrogen atoms, with little or no oxygen present.

The key difference between edible oils and diesel oil lies in their chemical structures. Edible oils contain fatty acids that are more easily metabolized by the human body for energy production. The presence of unsaturated fatty acids, like those found in olive oil, corn oil, and canola oil, provides nutritional benefits and promotes heart health when consumed in moderation.

In contrast, diesel oil contains hydrocarbons that are not meant to be ingested by the human body. These hydrocarbons lack the necessary chemical properties to be effectively broken down and utilized as an energy source. Ingesting diesel oil can be harmful and pose serious health risks.

Therefore, the chemical structural difference between edible oils and diesel oil determines their respective safety for consumption. Edible oils have a composition that is compatible with human metabolism, while diesel oil consists of hydrocarbons that are not suitable for ingestion.
