Explain the composition of triglyceride

(1) The components of triglyceride are single molecule of glycerol and 3 fatty acids.
(2) In glycerol 3 carbon atoms are present along with 30 n groups.
(3) Fatty adds consist of a long chain hydrocarbon with a carbxylic group at one end.
(4) Both of them form ester bond. This bond is saturated when single bonded carbons are present and unsaturated when double bonded carbon atom (—c = c—) are present
