Fat Functions
Triglycerides, cholesterol and other essential fatty acids--the scientific term for fats the body can't make on its own--store energy, insulate us and protect our vital organs. They act as messengers, helping proteins do their jobs.Because most fats have 3 fatty acids bonded to glycerol with 2 oyxgen atoms in each "ester" bond, the molecular formula is probably C54H108O6.

They act as messengers, helping proteins do their jobs.Answer and Explanation: The main elements that make up fats, or lipids, are carbon and hydrogen. The most basic lipids are made of long chains of carbon and hydrogen strung
The main components of edible fats and oils are triglycerides. The minor components include mono- and diglycerides, free fatty acids, phosphatides, sterols, fat-soluble vitamins, tocopherols, pigments, waxes, and fatty alcohols. The free fatty acid content of crude oil varies widely based on the source.
Fatty Acids. Fatty acids are the building blocks of the fat in our bodies and in the food we eat. During digestion, the body breaks down fats into fatty acids, which can then be absorbed into the blood. Fatty acid molecules are usually joined together in groups of three, forming a molecule called a triglyceride.
Fats are classified into saturated and unsaturated fats. Unsaturated fats are usually liquid at room temperature. These types of fats are healthy fats. Examples include fats from fish, oil seeds (sesame and sunflower), maize oil and ground nut oil and breastmilk.
The most obvious and defining difference between fats and oils is that fats are typically solid at room temperature whereas oils are liquid at room temperature. Fats and oils enter our diet through a variety of sources; Sources of fats include; Dairy products.
In simple terms, fats are animal fats whereas oils are vegetable oils. The other difference is fats tend to be solids at room temperature; on the other hand, oils tend to be liquid at room temperature.
The acid molecules can either be saturated or unsaturated. The fats and oils formed are also known as triglycerides. Like other esters, fats and oils are formed by a reversible reaction. Oils (liquids at room temperature) contain more carbon to carbon double bonds than fats (solid at room temperature).
Summary
- Introduction.
- Animal fats (butter, lard, tallow, chicken fat, and fish oils)
- Cocoa butter and cocoa butter alternatives.
- Lauric oils (coconut, palm kernel)
- Olive oil.
- Palm oil.
- Rapeseed (canola) oil.
- Soybean oil.
Fats are a group of chemical compounds that contain fatty acids. Energy is stored in the body mostly in the form of fat. Fat is needed in the diet to supply essential fatty acids, substances essential for growth but not produced by the body itself.
To form a solid, molecules need to pack together nicely, while in a liquid there is less order and the molecules flow around each other. Fat molecules are mostly made up of long, straight hydrocarbon chains. By definition, fatty molecules that form liquids are called oils and those that form solids are called fats.
There are four types of fats: saturated, monounsaturated, trans and polyunsaturated.
- Saturated fats.
- Monounsaturated fats.
- Polyunsaturated fats.
- Trans fats.
There are four major dietary fats in the foods we eat:
- Saturated fats.
- Trans fats.
- Monounsaturated fats.
- Polyunsaturated fats.
Fats and oils are composed of molecules known as triglycerides, which are esters composed of three fatty acid units linked to glycerol. An increase in the percentage of shorter-chain fatty acids and/or unsaturated fatty acids lowers the melting point of a fat or oil.
Which of the following is an example of fats? Explanation: Vegateble ghee is an example of fats. Glyceryl trioleate, Coconut oil and groundnut oil are the examples of oils. 3.
Some commonly eaten oils include: canola oil, corn oil, cottonseed oil, olive oil, safflower oil, soybean oil, and sunflower oil. Some oils are used mainly as flavorings, such as walnut oil and sesame oil. A number of foods are naturally high in oils, like nuts, olives, some fish, and avocados.

- Provision of energy. Fats are a source of energy in the human diet, together with carbohydrates and proteins, the other two main macronutrients.
- Structural component.
- Carrier of vitamins.
- Other biological functions.
- Dietary recommendations for fats.
- Total fat.
- Saturated fatty acids.
- Trans fatty acids.
You need a small amount of fat in your diet for healthy functioning. Oils and fats supply calories and essential fats and help your body absorb fat-soluble vitamins such as A, D, E and K. The type of fat is just as important for health as the total amount of fat consumed.
