## Abstract Porphobilinogen‐11‐^13^C was prepared by using benzyl 3‐(β‐methoxycarbonylethyl)‐4‐ (methoxycarbonylmethyl)‐2‐pyrrolecarboxylate as a starting material. A Vilsmeier‐Haak formylation with N,N′‐dimethylform‐^13^C‐amide gave the 2‐formylpyrrole, which was transformed into its oxime, and th
Photopyroelectric (PPE) study of some saturated (C5 : 0, and C23 : 0) and unsaturated (C18 : 2 and C18 : 3) free fatty acids was performed in a temperature range that included their melting points. The standard PPE conÐguration was used consistently during the experiment ; the special PPE case reque
