Abstract

The article presents the results of studying amino acids in honey and flowers of white acacia. It was found that in acacia honey, taurine accounts for the largest share, on average 0.173 mg / g or 20.79% of the total amount of amino acids. Acacia honey in large quantities contains proline - 0.110 mg / g, which is 13.22% of their total amount, glutamic acid - 0.095 mg / g or 11.42% and aspartic acid - 0.080 mg / g or 9.62%. Smaller amounts were found: cysteine - 0.36%, γ-aminobutyric acid - 0.60%, tyrosine - 0.72%, cysteine - 0.84%, methionine - 0.0.96% of their total. It was revealed that the total amount of nonessential amino acids in acacia honey is 0.384 mg / g, essential amino acids - 0.240 mg / g, immunoactive - 0.304 mg / g, glycogenic - 0.224 mg / g, ketogenic - 0.144 mg / g, proteinogenic - 0.624 mg / g and sulfur-containing amino acids - 0.190 mg / g. In the flowers of white acacia, the largest proportion is accounted for by proline, on average 2.989 mg / g, or 17.67% of the total amount of all studied amino acids. In large numbers, white acacia flowers contain aspartic acid - 2.468 mg / g, which is 14.59% of the total, glutamic acid - 2.045 mg / g or 12.09%, leucine - 1.274 mg / g or 7.53%. The total amount of nonessential amino acids in white acacia flowers averaged 10.290 mg / g, essential - 6.111 mg / g, immunoactive - 7.749 mg / g, glycogen - 6.240 mg / g, ketogenic - 3.877 mg / g, proteinogenic - 16.402 mg / g and amino acids with an S content of 0.180 mg / g.
