Abstract
The nitroxide spin labeled fatty acid 14‐proxylstearic acid (1) was tritium labeled (likely at the 2‐position) by a platinum black catalyzed exchange reaction in tritiated hot aqueous potassium hydroxide. The recovery of pure tritiated 1 was 565, with a specific activity of 260 mCi/mM.

14C-labeled chlorogenic acid (specijic activity 30.6 nCilmg) was synthesized by reaction of diphenylmethyl-I-0-ethoxy-carbonyl- 4,5-0-isopropylidenequinate ( V ) with 0,O-dimethylcarbonyl caffeoyl chloride-u-14C (VIII) followed by selective hydrolysis of the protecting groups.
## Abstract Investigations on a sample of New Zealand tall oil produced in the manufacture of wood pulp from New Zealand‐grown __Pinus radiata__, have shown it to contain trace quantities of the branched‐chain fatty acid (+)‐14‐methylhexadecanoic acid. Palmitic acid has also been shown to be presen
Proton relaxation enhancement (PRE) values for fatty acid spin labels bound to human serum albumin have been investigated using the inversion-recovery method at 24 MHz. At 0.1 mM protein concentration and a label-to-protein ratio of one-to-one, the PRE value for 12-Doxylsterate-albumin complex is 7.
