Sterols are lipids, having multiple ring structure. Eukaryotic membranes are made up of sterols, whereas archaeal membranes are made up of isoprenoid lipids. Isoprenoids lipids are made up of isoprene units from two to many thousand. Isoprene is an unsaturated hydrocarbon containing branched chains.

Answer 1

Question

Definition Definition Molecules that have multiple bonds between their carbon atoms. Alkenes are hydrocarbons with a double bond between two adjacent carbon atoms (R 2 C=CR 2 ), whereas alkynes are hydrocarbons with a triple bond between two adjacent carbon atoms R-C=C-R . These two groups are known as unsaturated hydrocarbons. They have fewer hydrogen atoms when compared with alkanes with same number of carbon atoms. The general molecular formula for an unsaturated hydrocarbon can be represented as C n H 2n +2 .
