✦ Synopsis

Abstract

Penicillin has been found to chelate Cu^2+^ although the chelating power of corresponding acylated aminoacids is very small. For comparison, the capacity of binding Cu^2+^ of a few structural analogues of penicillin has been determined by an ion exchange method described in a previous publication.

## Abstract The tendency of several N‐heterocyclic carbonic acids towards complex formation with Cu^2+^ has been estimated. The aromatic character of the heterocyclic ring system rather than the basicity of the donor group seems to have the strongest influence on chelate stability.

## Abstract The capacity of several hydroxyacids, ketoacids and hydroxyketones for binding Fe^3+^ has been compared by an indirect colorimetric method. There is evidence that chelate formation occurs with 1,3‐dihydroxyacetone, lactic acid and pyruvic acid.

## Abstract Complex formation of substituted amino acids with Cu^2+^ has been studied by use of ion exchangers. Acylation of the amino group results in a heavy decrease of coordination tendency.

## Abstract The capacity of forming metal chelates of a few α‐pyridyl carbinols and of an α‐piperidyl carbinol with Cu^2+^‐ and Ni^2+^‐ions has been determined. As far as the stability of the chelate ring is concerned, pyridyl‐(2)‐carbinol is almost as strong a complexing agent as oxine. Introducti

## Abstract Exchange reactions on metal protein complexes have been studied. A fraction of ovalbumin has been found, the affinity of which is greater for Fe^2+^ than for Cu^2+^. The meaning of the relative stabilities of metal protein complexes for enzymatic processes is discussed.
