Shortly, lightweight, inexpensive, precision, space‐filling atomic models particularly suitable for constructing macromolecules of biological interest will reach the scientific community. The availability of the models, the Corey‐Pauling‐Koltun, or C‐P‐K Models, will conclude a...
The aggregation properties of S‐carboxymethyl bovine serum albumin (SCM‐BSA) have been shown to be greatly influenced by the presence of thioglycollide esters in the thioglycollic acid used as a reducing medium. Pure thioglycollic acid gives a product which is aggregated at both pH 7 and 9....
The melting characteristics of unfractionated yeast s‐RNA in neutral aqueous solution have been examined by high‐resolution proton magnetic resonance spectroscopy. These studies indicate that the bases of s‐RNA become rotationally activated at lower temperatures than their associated ribose...
Anomalous optical rotatory dispersion (ORD) is induced in symmetric dyes when bound in metachromatic complexes with chondroitin sulfates (ChS) and kerato sulfate (KS) from mammalian and shark origin as well as with heparin (H) providing inference that secondary structures exist in these...
The irreversible kinetics of polypeptide denaturation and renaturation is discussed in terms of the Zimm‐Bragg equilibrium model. An exact solution is presented for situations in which the back reaction is negligible. The solution is given in terms of parameters which are rate constants for the...
Poly‐N5‐(3‐hydroxypropyl)‐L‐glutamine (PHPG) samples of molecular weights from 20,000 to 140,000 were synthesized by the action of 3‐amino‐1‐propanol on poly‐γ‐benzyl‐L‐glutamate. PHPG is freely soluble in water and in a variety of organic solvents and was shown to be...
