Procedures for the microestimation of nitrogenous phosphatide constituents.
This paper describes procedures for the separation and quantitative estimation in minute amounts of several nitrogenous substances normally encountered as constituents of phosphatides; viz., ethanolamine, choline, and serine. The work is based on techniques employing paper chromatography, previously applied to the investigation, in a qualitative fashion only, of tissue lipides (1) ; its princip...

when expressed as a percentage of the total nitrogen. This observation is in agreement with those recorded previously for typical storage organs. 3. The two plants contained very large amounts of the imino acid, azetidine-2-carboxylic acid. Nitrogen present in azetidine-2-carboxylic acid represented more than 50% of the total nitrogen of Polygonatum rhizome. The imino acid was also present in h...
متن کاملEffects of Potassium Deficiency and Excess upon Certain Carbohydrate and Nitrogenous Constituents in Guayule.
The nature of the carbohydrates of translocation and the reserve carbohydrates in guayule has only recently been elucidated. McRARY and TRAUB (28) isolated a fructosan, tentatively identified as inulin, and HASSID et al. (19) definitely characterized this substance as inulin. Later, TRAUB and SLATTERY (41) showed that in addition to inulin, levulins are also present in guayule tissue, and in re...
متن کاملChanges in Certain Water-soluble Nitrogenous Constituents of Burley Tobacco during Curing.
Introduction An investigation of the chemical changes that take place in tobacco during curing is in progress at the Kentucky Agricultural Experiment Station. Attempts are being made to determine what the normal changes are and how they are influenced by such variables as temperature and relative humidity, which have been shown to influence the final quality of tobacco. A study of this type add...
