This try things out was performed to impress upon the specialist about the different properties and characteristics of lipids which includes its solubility and its difficulty with regards to it is components. Quality for solubility tagged along the aphorism " like dissolves like” since coconut essential oil was blended in chloroform, ether, and carbon tetrachloride. The emulsification of excess fat in coconut oil was also done and the only the dilute ?ggehvidestof solution demonstrated a positive effect. The saponification reaction was also executed which is the focal procedure in the production of cleansing soap. Cholesterol, a simple lipid, was also examined in different color reactions which usually yielded to a negative product. INTRODUCTION


1 . To find out the different houses of lipids

2 . To be aware of observe the solubility of fats in extremely and non-polar solvents a few. To know the reaction of coconut oil in litmus daily news

4. To В form triglycerides from various fatty acids through saponification a few. To study the effects of complex lipids in color reactions


Lipids are found being water absurde but they are located to be soluble in body fat solvent. They are heterogeneous band of fatty acids. В They incorporate fats, natural oils, waxes and also other related chemicals. В They are oily or perhaps greasy chemicals. В Hence they are hydrophobic in characteristics. Proteins, polysaccharides, DNA and RNA happen to be macromolecules. В Lipids areВ not generally classed as macromolecules, even though they share a lot of features of macromolecules. В Such as: lipids produced as geradlinig polymers and in addition they self build intoВ larger constructions.

Lipids are compounds getting the following qualities:

• They can be insoluble in water

• Solubility in one or more organic solvents, such as ether, chloroform, Benzene, Acetone which are generally called as fat " solvents". • Some marriage to the fatty acids as esters either real or potential. • Possibility of utilization by simply living creatures.

Classification Of Lipids:

There is no sole, internationally approved system of category for the lipids obtainable. В What they are called of these compounds, however , do fall into specific categories because the aspect structures present are considered. Bloor's classification is mostly adopted by modifications as follows:

Simple Fats:

Simple fats are esters of fatty acids with various alcohols. They consist of mainly fatty acids and alcohols alone. В They are further divided into two classes specifically, Neutral body fat and waxes. a) Neutral fats:

They are really triesters of fatty acids with glycerol. Triacyglycerol is an example for Neutral fats. b) Waxes: В В

Waxes are esters of fatty acids with higher delicioso hydroxy aliphatic alcohols. В True waxes, cholesterol esters and vitaminВ A and D esters are case for waxes.

Compound Lipids:

They are the esters of fatty acids containing groupings, other than and in addition, to an alcoholic beverages and essential fatty acids. a) Phospholipids:

In addition to fatty acids and alcohol presence, В they also contain phosphorous, nitrogenous facets and other replacement groups. В Lecithin and cephalins happen to be examples to get phospholipids.

b) Glycolipids:

Lipids containing carbohydratesВ are referred because glycolipids. That they contain an special alcoholic beverages moiety referred to as sphingosine or sphingol and nitrogenous bottom. В They cannot have phosphorous. Gangliosides and cerebrosides are examplesВ of compounds fats. c) Sulpholipids:

Lipids with sulfate teams are referenced as sulpholipids.

d) Lipoproteins:

When lipidsВ contain protein they are referred to as lipoproteins. Case chylomicrons, VLDL, LDL andВ HDL.

Derived Fats:

Derived fats are fats obtained upon hydrolysis in the simple...
