Lipids
The heterogeneous classes of organic compounds that are not water-soluble but are dissolved in organic solvents that are non-polar in nature are termed lipids. They are a long chain of fatty acids and esters of alcohols. Lipids are generally seen in several plants, microorganisms, and animals. They are utilized as insulation, components of the cell membrane, hormones, and molecules for the storage of energy.
Glycerophospholipid
Glycerophospholipid is the most abundantly occuring phospholipids found in the biological membranes. Lipids include a group of organic compounds like fats, hormones, oils, waxes, vitamins etc. They are non-polar molecules and are insoluble in water. Lipids play an important role in biological systems. They are the building blocks of our cell membranes, store energy and are involved in signaling.
Structure Of Camphor
A terpene with the molecular formula of C10H16O is a waxy, white color solid known as camphor. It is flammable. It also possesses a very pungent taste and a strong odor. There are various sources for extracting camphor from natural products such as the wood of the tree of camphor laurel. Sublimation of wood and steam distillation are some of the methods involved in obtaining camphor.
Glycolipid In Organic Chemistry
Glycolipids are lipids that are an important class of organic compounds in chemistry that have simple to complex applications. They contain carbohydrates, fatty acids, sphingolipids or a glycerol group. In other words, they are the modifications of lipids like acylglycerols, prenols and ceramides. They are all part of a wider group of compounds known as glycoconjugates.
Diterpenoid
The terpenoid class includes diterpenoids, which are chemical compounds with 20 carbon atoms. They are made up of four isoprene units and are derived from geranylgeraniol, a C20 precursor. They have a C20H32 basic structure. These characteristics distinguish diterpenoids from simple terpenes, which have just 10 carbon atoms.
Explain why the melting points of unsaturated fatty acids are lower than those of
saturated fatty acids.
Melting point of a system depends on how efficiently that system is packed.
More closer the packing is, higher is the melting point.
Saturated Fatty Acids
They consist of saturated C-C bonds and doesn't have any other functional groups than -COOH.
Their system is ordered like polar heads are at one side next to each other while alkyl chains also take composition where they lie next to each other and fit perfectly.
Unsaturated fatty acids
This system also consists a polar COOH head group and non polar tail-alkyl chain.
This alkyl chain consists at least one unsaturated π C,C double bond.
This system is already unstable as alkyl chains are present away from each other.
System is not ordered because of presence of cis double bonds which causes weak intermolecular interactions. With increase in double bond, the intermolecular interactions get weak and melting point is therefore less.
