✦ Synopsis

The brown algae are characterised by their accumulation of polysaccharides, the more important ones being laminarin, fucoidin and alginic m i d . It has been established by Bidwell et al. (1$ 2 ) , that alginic acid is the most rapidly accumulated insoluble product on photosynthesis. The rapid appearance of such a large proportion o f photosynthetic carbon in alginic acid suggpsts a possible method for the biosynthesis oj radioactive alginic acid-C-14 (generally labelled, G). Such a svnthesis is now carried out on laboratory scale and the details are given. The radioactive alginic acid-C-II(G) thus synthesised finds many uses, such as ( 1 ) j o r quantitative determination and estimation of alginic acid present in various seaweeds and ( 2 ) for ascertaining the role alginic acid plays in the metabolism of brown algae.

## Abstract A simple procedure is described for preparing^125^I‐labelled alginic acid. The reducing terminal of alginic acid is derivatized with tyramine through the formation of Schiff base which is subsequently reduced with sodium cyanoborohydride.

## Abstract A procedure for the facile preparation of labelled carboxylic acids from labelled α‐amino acids has been described. The reaction is attractive for the small scale synthesis of such compounds.
