Study of amino acids in pollen's composition

Abstract

Biological value of pollen resulting from large and varied content in essential amino acids, essential for life, amino acids that can not be produced by bees, which is why it is necessary to administer their food. Compared with some animal products, amino acid content of pollen is larger and more varied. Composition and quantity of amino acids in pollen was detected in specific analyzers at the Metrology and Automation Centre of Academy of Scientific Research of Moldova. The maximum amount of amino acids found in collected pollen from lime, in June -162.243 mg/g. Pollen from sunflower constituted approx. 121.100 mg/g of amino acids. Of total amino acids in pollen, the largest share is glutamic acid from 16.503 to 26.158 mg/g, proline 15.280 to 22.543 mg/g and asparagic acid 11.529 to 16.654 mg/g. Were detected small amounts of methionine from 0.495 to 1.614 mg/g and tryptophan from 1.281 to 2.962 mg/g. Quantity of amino acids is not identical in pollen and largely depends on the season and on that species that was collected.
