Phospholipids and sphingolipids are the amphipathic backbone of every biological membrane, the precursors of signalling molecules, and — most importantly for NEET PG — the substrates whose accumulation causes the classic sphingolipidoses (lysosomal storage diseases). This note builds the structural logic first, then converts it into the enzyme-defect tables that the exam loves. Membrane lipids divide into two grea…
