Studies on the Surface Active Germicides. I

The insulin active surface problem; 3D studies on insulin analogues.

Studies on subfragment-I, a biologically active fragment of myosin.

The relationship between the structure and function of the myosin molecule is of considerable importance in the understanding of the molecular mechanism of muscle contraction. The nature of the adenosine triphosphatase (ATPase) site and the subunit structure are of special interest in this respect. The hydrolysis of ATP by myosin appears to link the conversion of chemical energy to the mechanic...

Studies on the Effect of Synthetic Surface-active Materials on Bacterial Growth. II.

In a previous communication (Katz and Lipsitz, 1935), the effect of a certain synthetic surface-active material on the growth of Mycobacterium smegmatis was discussed; this work has now been extended to include three more compounds, varying in chemical structure. These materials possess substantially the same properties as the alkylated naphthalene sulfonate originally employed, i.e., remarkabl...

Adsorption of Vitamin C on a Fullerene Surface: DFT Studies

Density functional theory (DFT) calculations were performed to investigate adsorptions of vitamin C (Vit) on the surface a fullerene structure (Ful) in gaseous and water–solvated systems. Two models of Vit including OVit and MVit were created based on the original structure of Vit for OVit and methylation of all hydroxyl groups for MVit. All singular and hybrid structures were optimized and the...
