No. I have the book. But doesn’t tell me much.
The last picture number 4 is 3 amino acids join together.
The last picture number 5 is a Triglyceride made up of glycerol and 3 fatty acids.

C) Is a Phospholipid. Made up of 2 fatty acid chains, 1 glycerol and one negatively charged Phosphate head.
Function: Phospholipids make up the cell membrane in Phospholipid bilayer. Its hydrophilic phosphate head allows hydrophilic molecules to pass through into the cell membrane while repelling hydrophobic molecules. This gives rise to the selective permeability of the cell membrane.

Its organic chemistry dear. Not biology. And the nomenclature is pretty easy if you understand it.
lol my bio class teach that. and oh okay. I couldn’t identify the issue.
OMG, I remember doing this in chemistry lol, but it feels like ages since I’ve last done it 
Hmm, I’d recommend checking this out:
lmAO you’re from sg too. That brings back bad memories 
Biology is the natural science that studies life and living organisms, including their physical structure, chemical processes, molecular interactions, physiological mechanisms, development and evolution.[1] Despite the complexity of the science, there are certain unifying concepts that consolidate it into a single, coherent field. Biology recognizes the cell as the basic unit of life, genes as the basic unit of heredity, and evolution as the engine that propels the creation and extinction of species. Living organisms are open systems that survive by transforming energy and decreasing their local entropy[2] to maintain a stable and vital condition defined as homeostasis.[3]
