What are the 4 classification of lipids?
Lipids are a class of macromolecules that are nonpolar and hydrophobic in nature. Major types include fats and oils, waxes, phospholipids, and steroids. Fats are a stored form of energy and are also known as triacylglycerols or triglycerides. Fats are made up of fatty acids and either glycerol or sphingosine.
What are the classifications of lipids?
There are two major types of lipids- simple lipids and complex lipids. Simple lipids are esters of fatty acids with various alcohols. For eg., fats and waxes. On the contrary, complex lipids are esters of fatty acids with groups other than alcohol and fatty acids.
What are lipids Class 9?
Lipids refers to a group of compounds such as oils, steroids, waxes, and fats that we can find in living organisms. Moreover, eukaryotes and prokaryotes both possess these that play an important role biologically. For instance, membrane formation, protection, insulation, energy storage, cell division, and more.
What are lipids classify them and give at least one example of each?
There are different types of lipids. Some examples of lipids include butter, ghee, vegetable oil, cheese, cholesterol and other steroids, waxes, phospholipids, and fat-soluble vitamins. All these compounds have similar features, i.e. insoluble in water and soluble in organic solvents, etc.
What is a triglyceride monomer?
The monomers of triglycerides are fatty acids and glycerol. Glycerol is a type of alcohol. Triglycerides are made up of monomers of glycerol molecules each bonded to three fatty acid “tails.”
Classification of Lipid: A) On the basic of Reaction with NaOH / KOH: B) On the basis to Products of Hydrolysis: Oils: Unsaturated fatty acid + glycerol. Waxes: Fatty acids + mono or dihydric alcohol. Simple glyceride: Contains same fatty acids. . Mixed glyceride: Contains different fatty acids.
What are the different types of non-nonsaponifiable lipids?
Nonsaponifiable lipids include steroids, prostaglandins, and terpenes. Within these two major classes of lipids, there are several specific types of lipids important to life, including fatty acids, triglycerides, glycerophospholipids, sphingolipids, and steroids. Each of these categories can be further broken down.
What are the criteria for the solubility of lipids?
These solubility criteria are not absolute. Lipids were therefore defined as compounds containing in their molecule an aliphatic chain (chain consisting of — CH 2 —) of at least 8 carbon atoms. Some short-chain fatty acids (like butyric acid, in C 4) are the only exceptions to this rule.
What is the difference between simple and complex lipids?
Simple lipids are esters of fatty acids with various alcohols. For eg., fats and waxes. On the contrary, complex lipids are esters of fatty acids with groups other than alcohol and fatty acids. For eg., phospholipids and sphingolipids.
