Asked Jan 16, 2020

How are there thousands of types of different organic molecules found in cells, but just four different types that make up most of the dry weight of living organisms? If we are multi-cellular creatures, how is that we have four different types of molecules that make up most of the weight, if cells have thousands of different types of molecules. Wouldn't we have an insanely high number of types of organic molecules in our bodies then, since we are multicellular organisms? Thanks ?
