A SPECTROPHOTOMETRIC METHOD FOR THE MICRODETERMINATION OF HEXOSAMINES

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

[A modified method for the microdetermination of citric acid].

An investigation of the different steps in the method of Weil-Malherbe & Bone (1949), as modified by Taylor (1953), has led to an altered procedure for citric acid determination, with increased sensitivity and accuracy. The main modifications involved are the use of (i) a higher concentration of sulphuric acid during the formation of pentabromoacetone, and (ii) a thiourea-borax-sodium sulphide ...

Method for the determination of hexosamines in tissues.

During the course of investigations on the metabolism of hexosamines in animal tissues, absorption spectra of the color produced in the hexosamine method of Elson and Morgan (1) revealed the presence of interfering chromogens. Similar types of interference have been noted in studies on the jelly coat of sea-urchin eggs (2), Neurospora (3), and pineapple plants (4). Hexosamines were found to pro...
