A Study of the Behaviour of Some Sixty Amino Acids and Other Ninhydrin-reacting Substances on Phenol-“Collidine” Filter Paper Chromatograms, with Notes as to the Occurence of Some of them in Biological by: In addition, Van Slyke developed the so-called Van Slyke apparatus, which can be used to determine the concentration of respiratorygases in the blood, especially the concentration of sodium bicarbonate.   Other general topics covered include the Kjeldahl procedures to determine nitrogen compounds; oxygen flask combustions; determination of fluorine; and microhydrogenation. The final chapters present the modification of the procedure for the determination of oxygen using Edition: 2.

Analytical and Chemical Methods As in previous investigations (9), the micro-Kjeldahl and manometric van Slyke methods were used for N and amino N determinations, respectively; colori- metric methods were used for the determination of and cystine ; while the other amino acids were determined microbiologically (9).Cited by: determination. The Kjeldahl method for nitrogen has undergone many modifications since its inception, usually with the object of decreasing the period required for digestion. In the last 15 years, wide-spread use of micro modifications of this method has introduced further variations in the procedure. The Kjeldahl method has had such universal acceptance. Important parameters on method validation (accuracy, precision, LOD, LOQ) are presented in Table 1A, Table on the results obtained from determination of iodine by spectrophotometric and ICP-MS methods, the results were agreed well with the certified values of the SRM and RM, which indicate good performance of the two methods for iodine by: Among species, the content of proteinaceous nitrogen was high, with an average of % of the total nitrogen. From data of total amino acid and total nitrogen, specific nitrogen-to-protein.

This chapter discusses the estimation of side chain groups in the intact protein. THE side chain groups are derived from amino acids in the peptide chain, their importance lies not so much in their relationship to particular amino acids, but in the physico-chemical Cited by: 8.

Soc., , Cited by: ALPHA-AMINO NITROGEN.-The VAN SLYKE (30) method for the estimation of amino nitrogen has been examined by STUART (29) who found that high results are obtained when using water or alcoholic plant extracts. A number of substances such as ammonia, dihydroxy phenols, and tannic acid were found to yield nitrogen with nitrous acid. Van Slyke and Neill5, factors are obtained for the conversion of the observed Pco to volume (S.C.) of the gas in the blood or the solution returned to the Van Slyke appa- ratus.
