Determination of monoamino monocarboxylic acids by quantitative paper chromatography

Determination of monoamino monocarboxylic acids by quantitative paper chromatography.

Many methods for chromatographic separation of amino acids are now available, but their subsequent determination, generally employing ninhydrin, often leaves much to be desired. It was felt, therefore, that there was a need for a simple method of analysis based on the convenient paper technique and employing some means of determination less fickle than ninhydrin colorimetry. The method now pres...

Quantitative Structure-Property Relationship to Predict Quantum Properties of Monocarboxylic Acids By using Topological Indices

Abstract. Topological indices are the numerical value associated with chemical constitution purporting for correlation of chemical structure with various physical properties, chemical reactivity or biological activity. Graph theory is a delightful playground for the exploration of proof techniques in Discrete Mathematics and its results have applications in many areas of sciences. A graph is a ...

Monoamino monocarboxylic acid content of preparations of herbage protein.

The quantitative determination of amino-acids in urine used in conjunction with one-dimensional paper chromatography.

The value of paper chromatography in the study of the amino-acids of urine in disease has been shown in particular by Dent (1946, 1948). Although present methods of oneor two-dimensional piper chromatography can indicate important quantitative changes to the observer, there is some difficulty in conveying impressions to another, e.g., to a clinician or to a reader of a paper. It does appear tha...

Separation of Amino Acids by Paper Chromatography

Chromatography is a common technique for separating chemical substances. The prefix “chroma,” which suggests “color,” comes from the fact that some of the earliest applications of chromatography were to separate components of the green pigment, chlorophyll. You may have already used this method to separate the colored components in ink. In this experiment you will use chromatography to separate...
