The proximate and mineral composition of three leafy vegetables commonly consumed in Lagos, Nigeria

Analysis of proximate composition and mineral nutrients of three commonly consumed vegetables Amaranthus cruentus, Celusia argenta and Corchorus olitorius leaves was carried out using standard methods of food analysis. The mean leaves moisture content is 23.57, 15.58 and 30.90% respectively for A. cruentus, C. argenta and C. olitorius. The vegetables have high ash content ranging from 21.30...

Selective synthesis applying amino acids with basic side chains as peptide precursors

  Synthesis of protected amino acid derivatives has long been established as one of the most useful methods for peptide coupling, with applications in studies involving receptor-binding affinities and in protein stereochemical studies to elucidate enzymatic mechanisms. Amino acid esters incorporating glycine, proline, phenylalanine and related methyl esters have often been synthesized due to their usefulness,...

Seasonal variation of some physico-chemical properties of borehole water in Abraka, Nigeria

  The influence of seasonal changes on the properties of the borehole water in Abraka Ethiope east LGA Delta state, Nigeria was investigated. Composites samples from 7 representative quarters in Abraka township were collected and assessed for both dry and wet seasons. The vales of the various parameters were as follows: pH 6.3 to 7.1 for dry season and 6.2 to 8.00 for wet season; conductivity 62 to 84...
