Abstract
WRINCH1 recently proposed that in monolayers or globular molecules of proteins, polypeptide chains are knitted into a fabric by the bonding process which Frank2 had shown to be required in keratin to make permissible the structure Astbury deduced for it by X-ray crystallography. It is desirable to estimate the energy balance of this process, which is chemically analogous to lactam-lactim tautomerism, or to the ring closure in sugars associated with mutarotation.
