The present work includes synthesis of new series heterocyclic derivatives containing 6-amino-1,3-dimethyl uracil moiety linked to 1,2,4-triazole [6-8 and 10]. first way reaction 6-amino-1,3-dimethyluracil with ethyl chloroacetate K2CO3 as catalyst in DMF solvent gives ester derivative [1]. Then, compound [1] was converted into (semicarbazide, thiosemicarbazide, phenylsemicarbazide hydrazide de...
abstract amino acids are building blocks of proteins, and play a vital role in living beings existence and their functionality. the interaction of these compounds with metal ions is of great importance to biochemists, and chemists, because their functions can be utilized as a model in understanding enzymes mechanism for transport of metal ions to tissues. among twenty essential amino acids w...
Abstract The present study aims at the identification and investigation of fatty acid and amino acid profiles in male and female Liza aurata in the southern part of the Caspian Sea, in reproductive (autumn) and non-reproductive (spring) seasons. The results showed difference between the total fatty acids levels in the sexes. Analyses of fatty acids indicated a higher percentage of C16:0, C...
