Updated on 23rd June, 2023 , 6 min read
Fats and oils are necessary macronutrients for the animal body. Fats and oils are both composed of carbon (C), hydrogen (H), and oxygen (O). These elements combine to produce chains of molecules known as fatty acids. Individual molecules of fatty acids can be saturated or unsaturated. The fatty acid mixture influences whether the final chain is saturated or unsaturated. The primary distinction between fats and oils is that fats are formed mostly of saturated fatty acids, which solidify at room temperature, and oils are composed primarily of unsaturated fatty acids, which are liquid at room temperature.
Fat is often used in nutrition, biology, and chemistry to refer to any ester of fatty acids or a combination of such compounds, most typically those found in living creatures or food. At room temperature, they are solid. They are both saturated and trans fats. A fatty acid is modified to extend its shelf life. The method by which this transformation occurs is known as hydrogenation.
Oils are fats that are liquid at room temperature. This category includes unsaturated fats. Consuming foods high in unsaturated fat helps lower cholesterol. Unsaturated fats are classified into two categories. Polyunsaturated and monounsaturated fats. Nuts, vegetable oils, and avocados all contain monounsaturated fat. Consuming foods high in monounsaturated fats aids in cholesterol control by maintaining high levels of good HDL cholesterol and reducing levels of harmful LDL cholesterol. Replacing saturated fat with polyunsaturated fat in the diet may aid in the reduction of LDL cholesterol. Polyunsaturated fats are classified into two categories. They are Omega 3 and Omega 6 fatty acids.
Saturated fat and trans fat are the two primary forms of fat.
Monounsaturated fats and polyunsaturated fats are the two forms of unsaturated fatty acids.
Oils are not a food category, but they do supply necessary elements and are thus included in the USDA dietary guidelines. It should be noted that only minimal doses of oils are suggested. The majority of the fats you consume should be unsaturated. The greatest source of these healthy fats is oils (rather than solid fats). While some oil is necessary for health, oils nonetheless contain calories. In reality, each tablespoon of oil or solid fat has around 120 calories. So, attempt to minimize the intake of oil to keep the total calorie intake low.
The following are some of the similarities between fats and oils-
The following table gives details about the difference between fats and oils-
Parameters |
Fats |
Oils |
Meaning |
Fats are oily substances found under the skin or surrounding organs in the animal body. |
Oils are viscous liquids found in plant fruits or seeds. |
At Room temperature |
At room temperature, it is solid. |
At room temperature, liquid. |
Saturation |
Saturated fatty acids make up the majority of fats. |
Oils are mostly made up of unsaturated fatty acids. |
Types |
It comes in two varieties: Saturated and Trans Fats. |
It comes in the form of monounsaturated and polyunsaturated fats. |
Influence |
Fats enhance the likelihood of developing cardiovascular disease. |
Oils reduce the risk of cardiovascular disease. |
Obtained From |
The majority of them are obtained from animals. |
The majority of it is obtained from plants. |
Level of Cholesterol |
Fat raises cholesterol levels in the blood. |
Oils help to decrease blood cholesterol levels. |
Examples |
Cream, butter, beef fat |
Vegetable oil, fish oil or corn oil |
Storage |
Animals store fat in their livers and behind their skin. |
Plants store oils in their seeds and fruits |
Oxidative Rancidity |
Fats have a high level of oxidative rancidity. |
Oils have low oxidative rancidity. |
Adipocytes |
Adipocytes are the specialized cells in animals that store fat. |
Plants store oils in fat granules. |
Some of the key points to remember are as follows-
The following are some of the sample questions for the difference between fats and oils-
Q.1 What exactly are oils?
Ans. Oils are nonpolar chemical compounds that are combustible, surface active, and water-insoluble. They are liquid at room temperature, unlike fats. Oils are lipophilic and include hydrocarbons (mix well with oils). Oils might be animal, vegetable, or petrochemical in nature. Oils can be organic or mineral in nature. Oils are used to make paints, plastics, crayons, and other products, as well as in food, fuel, and medicine.
Q.2 What kinds of fat are beneficial?
Ans. Monounsaturated and polyunsaturated fats are referred to as "healthy fats" since they are beneficial to your skin, cholesterol, and overall health. These fats may aid in lowering the risk of heart disease and stroke. Reduce LDL cholesterol levels while increasing HDL levels.
Q.3 What exactly are unsaturated fats?
Ans. Unsaturated fats are classified as oils. Unsaturated fats have double bonds in their fatty acid chains. Unsaturated fats are preferable to saturated fats since they help raise healthy cholesterol levels. They also help to maintain healthy brain function. Avocados, almonds, canola oil, olive oil, and other foods contain unsaturated fats.
Q.4 What exactly are fats? How do they come to be?
Ans. Triglycerides that are insoluble in water, soluble in organic solvents, and solid/semi-solid at room temperature are referred to as "fats." Fatty acids and glycerol are the two primary components of fat. Glycerol is an alcohol with three hydroxyl groups (OH). A lengthy carbon chain and a carbonyl group make up fatty acids. The fatty acids bind to the three hydroxyl groups, forming an ester connection via the oxygen atom. A fat molecule is formed as a result of this.
Q.5 Which of the following fats and oils has the highest melting point?
Ans. Because fats are more saturated than oils, they have a greater melting point than oils. The fatty acid chains in saturated fat have single bonds. The majority of animal fats are found to be saturated.

Ans. Monounsaturated and polyunsaturated fats are referred to as "healthy fats" since they are beneficial to your skin, cholesterol, and overall health. These fats may aid in lowering the risk of heart disease and stroke. Reduce LDL cholesterol levels while increasing HDL levels.
Ans. Fat, along with carbs and proteins, is one of the three basic macronutrients required by the organism. A healthy diet should include monounsaturated and polyunsaturated fats. Avocados, olive oil, nuts, seeds, and fatty fish are all good sources of these fatty acids.
Ans. Fat is the principal component of energy storage in the body, and it is used as a power source by the body. Fat also serves many other important functions in the body, and a balanced diet is necessary for overall health. Food fats are classified into three types: saturated, monounsaturated, and polyunsaturated.
Ans. Triglycerides, which are esters composed of three fatty acid units coupled to glycerol, are the building blocks of fats and oils. The melting point of fat or oil decreases as the number of shorter-chain fatty acids and/or unsaturated fatty acids increases.
