Protein Structure & Folding

Proteins are linear polymers of L-α-amino acids whose biological function is dictated entirely by their three-dimensional shape. This topic links basic chemistry (bonds, forces) to classic clinical disease — scurvy, Ehlers-Danlos, prion disorders and amyloidoses — and is a recurring source of "one-liner" NEET PG questions. Protein architecture is described at four hierarchical levels. Each higher level is built on…
