Acid-forming amino acids, effect on Ca bioavailability, 76... 

Since acid-forming amino acids are present primarily in proteins, a number of papers have reported the effect of feeding various levels of protein to human subjects. Sherman and Gettler (23) postulated that food ash determined the acidity or alkalinity of the urine. 

As a component of the condensation, the amine must also possess the effect of an asymmetrically inducing steric matrix and provide for a highly steroselective synthesis of the newly formed amino acid unit in the desired configuration. 

Trivalent rare earth cations form complexes with a series of hydroxycarboj lic acids and amino acids in aqueous solutions, some of which are listed in fig. 8. Earlier studies of Katzin (1968, 1969) revealed that these biological substrates effectively act as bidentate ligands toward the rare earth cations. Rare earth complexes with multidentate chelators were recently applied as receptors for zwitterionic amino acids of biological and artificial interests. Aime et al. (2001a) characterized the complexation behaviors of zwitterionic amino acids with oc-... 

Effects of L- -amino acid ligands - Stepping on the tail of enantioselectivity The naturally occurring -amino acids form a class of readily available strongly coordinating ligands, which exhibit broad stmctural variation. Moreover, their availability in enantiomerically pure form offers opportunities for enantioselective catalysis. Some derivatives of these compounds have been...
