Chelating properties of imino-bis(methylphosphonic) acids
Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 19821. Imino-bis(methylphosphonic) acids containing various substituants on the nitrogen atom have been synthesized, and their acid-base and chelating properties have been investigated. 2. Bulky substituents (t-C4H9 and cyclo-C6H11) on the nitrogen atom in these acids produce steric hindrance to dissociation in the third stage and affect the

Imino acid transport in yeast: The uptake of sarcosine
Biochimica et Biophysica Acta (BBA) - Biomembranes, 1973Abstract 1. 1. The properties of a sarcosine uptake system in nitrogen-starved cells of Saccharomyces chevalieri are described. The intracellular radioactivity accumulated corresponds to free sarcosine as indicated by radioautography. 2. 2. Internally accumulated [14C]sacrosine does not outflow when cells are resuspended in fresh buffer, but ...

N-Terminal Imino Acids and Gelatin Gelation
The Journal of Photographic Science, 1975AbstractThe N-terminal proline and hydroxyproline contents of gelatin can be determined quantitatively, after rcactiol' with cyanate. This forms the basis ofa method for estimating the average number of sites, per molecule, for initiating gelation, if unbroken sequences of the type -gly-im-im-gly-im-im- are required.

Membrane Transport in Disorders of Imino-Acid Metabolism
Archives of Pediatrics & Adolescent Medicine, 1967NEW KNOWLEDGE about intermediary metabolism of the imino acids in man, derived from investigations on the few patients with heritable disorders of proline and hydroxyproline metabolism, was reviewed by Efron. From an equally small number of such patients some fundamental characteristics of membrane transport of amino acids in the human kidney have also

Automated fluorometric amino acid analysis: The determination of nonprotein cyclic imino acids
Analytical Biochemistry, 1982Abstract The fluorometric detection of eight previously unstudied cyclic imino acids of plant origin following automated ion-exchange fractionation is reported. cis -4-Hydroxyproline, trans -4- and cis - and trans -5-hydroxypipecolic acids, acetylaminopipecolic acid, and 2,4- trans -4,5- rans - and 2,4- trans -4,5- cis -4,5,-dihydroxypipecolic ...

Extensive and detailed review articles and chapters on brain amino acids can easily be found in the literature, including handbooks of neurochemistry. To my knowledge, this is the first chapter to discuss separately data on imino acids (cyclic secondary imino acids) present in the nervous tissue. Thirty-two substances are listed by Himwhich and Agrawal

Reactivity of the imino acids formed in the amino acid oxidase reaction
Biochemistry, 1979The reactivity of the imino acids formed in the D- or L-amino acid oxidase reaction was studied. It was found that: (1) When imino acids reacted with the alpha-amino group of glycine or other amino acids, transimination yielded derivatives less stable to hydrolysis than the parent imino acids.

For rabbit jejunal brush border vesicles an 'imino carrier' has been defined as a sodium-dependent, alanine-resistant transporter of cyclic imino acids, while for intact rabbit jejunal and ileal epithelia an 'imino acid carrier' has been defined as a sodium-dependent transporter of both aliphatic and cyclic imino acids.
