With the new day comes new opportunities and positivity; we at BYJU'S Exam Prep have also come up with short notes on the topic, which is very important concerning the CSIR NET 2021 exam. Today's topic is 'Difference Between Animal Fats and Plant Fats'. This set оf shоrt nоtes fоr Biосhemistry hаve been metiсulоusly designed by оur exрerienсed subjeсt-mаtter exрerts, in оrder tо give yоu the mоst stаndаrd set оf study mаteriаls tо be fосused uроn. It becomes challenging to find the best notes as different materials are available on different websites. Here we аre оffering the best Biосhemistry nоtes thаt аre reliаble аnd саn be used by the students during their рreраrаtiоns fоr the uрсоming СSIR-NET 2021 exаm.
Fatty acids are the simplest form of lipids. They are the water-insoluble, long chain of hydrocarbons with one carboxyl group (R-COOH). They are a kind of lipids and serve as a source of energy.
These are of two types:
- Saturated fats have no double bonds. General formula: CH3(CH2)nCOOH. Due to high saturation rates, it remains in solid form at room temperature, commonly known as fats.
- Unsaturated fats have one or more double bonds. At room temperature, they remain in liquid hence, commonly known as oils.
Fats and oil are both made up of molecules known as triglycerides, which are esters consisting of three fatty acid units connected to glycerol. Triglycerides are the primary components of adipose tissue (body fat) and are major constituents of sebum (skin oils).
Animal fats are triglycerides containing mostly saturated fatty acids. The fats are stored in the liver and beneath the skin—examples: Butterfat and beef fat.
Plant fats triglycerides are unsaturated and polyunsaturated fatty acids. The plant fats are stored in the fruits and seeds—examples: sunflower oil, coconut oil, and olive oil.
Difference between Animal Fats and Plant Fats
|Animal Fats||Plant Fats|
|1. They can Easily line up; hence, they are solid at room temperature; commonly called fats||1. Because of the structure of plant cell, they bend, and so they cannot line up together to form solids thus are liquid at room temperature; commonly called oil|
|2. Iodine number (i.e., degree of unsaturation in fatty acid) of animal fats is lower||2. High iodine number|
|3. Oxidative rancidity is relatively high||3. Oxidative rancidity is relatively less|
|4. Stored in liver and beneath the skin||4. Stored as granules in fruits and seeds|
|5. The Reichert Meissl; indicates the volatility of fatty acid extracted from fats; the number of animal fats is higher||5. The Reichert Meissl number of animal fats is low|
|6. Stored by specialized cells known as adipocytes||6. Specialized cells are absent|
