the structural differences between fatty acids (cis and
trans double bonds), diacylglycerols, triacylglycerols, and
sphingolipids.
Lipids are biomolecule which is soluble in non-polar solvents and insoluble in polar solvents. Majorly lipids can be fatty acids. sterols, glycerides, (mono, di, tri), waxes, phospholipids. Eight categories from which lipids can be derived are - Fatty acids, glycerolipids, glycerophospholipids, sphingolipids, saccharolipids and polyketides.
Fatty acids are long aliphatic chain and contains carboxyl group at alpha carbon atom. It can be saturated or unsaturated , based on this property, causes fluidity in the membrane and high/low melting point.
Glycerides are esters formed from glycerol's and fatty acids which is very hydrophobic. Based on number of ester bonds it can be monoglycerides, diglycerides and triglycerides.
Phospholipids are consist of two fatty acids chain linked to a glycerol by ester bond and a phosphate group which is esterified to an organic molecule (X) such as choline, ethanolamine, inositol, etc. It can be Phosphatidylethanolamine, phosphtidylcholine, etc. It is a key component of cell membrane due to its amphiphilic property (tail-FA, hydrophobic and head-phosphate group, hydrophilic).
Sphingolipids contains backbone of sphingoid bases, which is a aliphatic amino alcohols i.e. sphingosine. it can be sphingosine, ceramide, sphingomyelin, cerebroside, ganglioside, etc.
