“…Formalization of the study of significance of the clusters can be found in ref 19. Very diverse classifications have been carried out with success (organic molecules according to their interaction with GLC phases (20), fatty acids according to their metabolic pathway (9), photographic material in a process control situation ( 19)).…”

The aim of this paper is 2-fold. (1) To propose the use of a group of mathematical techniques, called clustering, in the elucidation of complex metabolic relationships. (2) To apply clustering for the identification of related groups of saturated fatty acids having a common metabolic pathway for their biosynthesis in the milk fat of lactating goats. In this way, four groups of branched-chain fatty acids and two groups of straight-chain fatty acids are identified; the odd-numbered iso-, the even-numbered iso-, the anteiso-acids and the branched-chain fatty acids with methyl substitution in the chain, the odd-numbered straight-chain and the even-numbered straight-chain fatty acids. The long-chain fatty acids are not part of any group. The different metabolic pathways for their biosynthesis are discussed. From the results, it is concluded that clustering is indeed a potentially useful tool in the study of complex metabolic relationships.

A new non hierarchical clustering procedure is used to evaluate an existing classification of iron meteorites. It is shown that the classification obtained resembles the existing classification to a large degree. This confirms the consistency of both the clustering method and the existing classification. The principal disagreement between the existing classification and the clustering concerns the so‐called anomalous meteorites. The reason for this disagreement is discussed.
