Glycine betaine and glycine betaine analogues in common foods
Abstract In this study we have surveyed the betaine content of a wide range of foods commonly found in the western diet. Glycine betaine, proline betaine (stachydrine), trigonelline andExpand

The betaine content of New Zealand foods and estimated intake in the New Zealand diet
Abstract We have measured the glycine betaine, proline betaine, trigonelline and dimethylsulphoniopropionate (DMSP) content of 74 predominantly processed foods. Combining these data with a previousExpand

Aracyl triflates for preparing fluorescent and UV absorbing derivatives of unreactive carboxylates, amines and other metabolites
Abstract Aracyl trifluoromethanesulfonate (triflate) reagents alkylate the unreactive carboxyl groups of betaines. The reagents also derivatise tertiary amines, amine oxides, phosphates andExpand
