The optical rotatory dispersion (ORD), and to a lesser extent the circular dicliruisni (CD) of the proteins tropomyosin and myosin have been extensively studied. The effect of aging and of certain reagents on these optical properties, relating to helical contents, were observed. As expected, spectra

Tropomyosin is a protein that controls the interactions of actin and myosin as a part qfthe regulation of muscle contraction. The 420 A' long a-helical coiled-coil molecules form long filaments, both in muscle and in crystals. The x-ray diffraction data from tropomyosin crystals have indicated large
## Abstract A series of castor oil adducts were synthesized by esterification of castor oil with acid anhydrides: phthalic, maleic and succinic anhydrides. The chemical structure of castor oil and the prepared adducts were characterized by means of IR and ^1^Hβ NMR spectroscopy. The numberβaverage a
## Abstract Two series of hydrogels of poly[(acrylic acid)β__co__β(itaconic acid)] have been prepared by copolymerization in solution using tetrafunctional __N__,__Nβ²__βmethylenebisacrylamide (NMBA) as crossβlinker. The resulting polymer was swollen in water at 298 K to yield homogenous transparent
