✦ Synopsis


A class of fermion operators whose determinants can be calculated exactly has recently been noted. We observe that typically such operators can be chirally rotated into the free Dirac operator;

hence. their determinants are given by the chiral anomaly. Four-dimensional fermion determinants of this type are computed: the appearance of the Wess-Zumino anomaly term 1s noted.

The previously published synthesis of defined chiral triglycerides has been extended to the synthesis of their racemics. The combined use of the chiral-racemic pair of a triglyceride can now be used to accurately defne the effective specificity of a large number of lipases. As an example, we confirm
