3. The scientific discipline dedicated to understanding the role of lipid compounds in health, disease, and cellular processes

Etymology: "Lipidology" is a plain technical coinage, built from "lipid" and the suffix "-ology," meaning "the study of." "Lipid" itself comes from the Greek "lipos," meaning fat, and the "-ology" ending comes from the Greek "logos," meaning word, reason, or discourse, which came to mean systematic study. The pattern follows older scientific fields such as biology and geology, so the word reads as a self-explanatory label: the study of fats. The word's usefulness lies in its precision. Biochemists and physiologists needed a single name for research into fats and oils, separate from nutrition, which concerns diet, and from general biochemistry. Its formation is transparent, so anyone who knows "lipid" can work out its meaning at once.
