Abstract. Symplex Compounds.The great complexity of living cells is one of the chief difficulties in the analysis of the action of drugs Many of the functions of cells are carried out by means of proteins carrying active groups and since these proteins are acted upon by many drugs, the study of the reactions between active proteins and drugs provides valuable information regarding the more. Haemoglobin is one of the most important molecules in the animal kingdom. Its function is to carry oxygen to tissues. In lower invertebrates the blood pigment is present in the haemolymph and is not bound in cells. Later in the course of phylo- genesis haemoglobin remains associated with cells which produce it and in this form it reaches the peripheral circulation. In higher organisms the.

The haemoglobin of muscle according to Millikan loses carbon monoxide ten times as rapidly as blood haemoglobin, although their affinities are about the same. This variability of action on the part of haemoglobin is dependent on a difference in the globin portion as the haem molecules are identical.
