Molecular weight of onuphic acid

Molecular weight of poliovirus ribonucleic acid.

Purified poliovirus single- and double-stranded ribonucleic acids (RNA) were examined by electron microscopy. The length of both molecules was found to be 2.37 mum. The uncorrected sedimentation coefficient for single-stranded RNA is 33S, as compared to 27S for the RNA of tobacco mosaic virus. It is calculated from these results that the molecular weight of the sodium form of poliovirus is 2.6 ...

The Issue of Molecular Weight in Humic Acid Chemistry

Since the day humic substances have been isolated by Berzelius, they are commonly considered polymeric in nature. The biopolymer theory became so popular that the concept was embraced by most scientists for more than 1.5 centuries. It has provided a suitable hypothesis that is among other things not running afoul of with the elemental composition of the humic compounds, which shows relatively c...

High Molecular Weight Hyaluronic Acid Inhibits Fibrosis of Endometrium

BACKGROUND Elevated fibrosis has been found in patients with intrauterine adhesion, which indicates that fibrotic factors may play a critical role in formation of intrauterine adhesion. The aim of this study was to identify the effect of hyaluronic acid (HA) at high and low molecular weight on fibrosis of the endometrium in a mouse model of Asherman's syndrome. MATERIAL AND METHODS Endometrial ...

Synthesis of high molecular weight polyethylene using FI catalyst

A FI Zr-based catalyst of bis[N-(3,5-dicumylsalicylidene)-2′,6′­diisopropylanilinato]zirconium(IV) dichloride was prepared and used for polymerization of ethylene. The effects of reaction conditions on the polymerization were examined in detail. The increase in ethylene pressure and rise in polymerization temperature up to 35 oC were favorable for catalyst/MAO to raise the catalytic activity as...
