Question

choose the correct answer below.
a) triglycerides are made of a glycerol backbone and 3 glycogen molecules, resembling an \t\
b) triglycerides are made of a glycogen backbone and 3 fatty acids, and resemble \t\
c) triglycerides are made of a glycerol backbone and 3 amino acids, resembling an \e\
d) triglycerides are made of a glycerol backbone and 3 fatty acids, and resemble an \e\

Explanation:

Triglycerides are a type of lipid. Their structure consists of a single glycerol molecule covalently bonded to three fatty acid chains, and this structure visually resembles the shape of an "E". Option a is incorrect because glycogen is a carbohydrate, not a component of triglycerides. Option b is wrong as the backbone is glycerol, not glycogen. Option c is incorrect because amino acids are the building blocks of proteins, not triglycerides.

Answer:

d) Triglycerides are made of a glycerol backbone and 3 fatty acids, and resemble an "E"
