A method for analysing small samples of floral pollen for free and protein‐bound amino acids

Pollen provides floral visitors with essential nutrients including proteins, lipids, vitamins and minerals. As an important nutrient resource for pollinators, including honeybees and bumblebees, pollen quality is of growing interest in assessing available nutrition to foraging bees. To date, quantifying the protein-bound amino acids in pollen has been difficult and methods rely on large amounts...

Contents of Free Amino Acids in Mushrooms

The fruit bodies of 113 kinds of mushrooms were examined by amino acid analyzer to determine 20 free types of protein amino acids and 11 non-protein amino acids . (1) Though considerable difference was often found among species of mushroom, the average of total free amino acids was 213μ mol/g dry matter. (2) It was found that the amount of alanine, glutamic acid and glutamine was very high and ...

Free amino acids in cerebrospinal fluid.

Values for total amino acid nitrogen and for certain individual amino acids in cerebrospinal fluid have been reported in the literature. The values for total a-amino acid nitrogen show some variations, perhaps depending on the methods employed. Weichmann and Dominicke (I), using the Folin calorimetric method, report values of 1.2 to 2.0 mg. per cent, while Christensen et al. (2), using the mano...
