The text is a common IELTS Academic Reading passage that discusses the emergence of combinatorial chemistry . This branch of synthetic organic chemistry has become a significant "buzzword" or "in vogue" term within the pharmaceutical and biotechnology industries. Key Reading Answers The Core Structure — a dimer of flavonoids
: Describes the "innumerable" or "limitless" possibilities for combining molecules. Key Concepts in the Passage
Mathematicians would call this a "permutation and combination" problem. By mixing different molecular building blocks, chemists can create vast "virtual libraries" of compounds to test for new medicines or materials. How Does it Work?
