This article presents the nutritional value of shrimp on the strength of its nutrient composition and daily value (DV%). With its relatively lower lipid content (~ 1%), the DV (%) of 100 g shrimp for an adult human is 75%, 70% and 35% for eicosapentanoic acid + docosahexanoic acid, essential amino acids (methionine, tryptophan and lysine) and protein respectively. The lower atherogenic (0.36) a...

Three adult human subjects were maintained for 7 days (period I) on a protein-free formula diet containing the minimum daily requirements of the eight essential amino acids plus 40 g glycine. During the last 5 days of this period, the average daily nitrogen balances for the three subjects were +0.52, +0.71, and +0.30 g, respectively. During the next 7 days (period II), valine was withdrawn from...

Gracilaria changgi, an edible seaweed was analyzed to determine its proximate chemical composition, mineral elements, vitamin C, b-carotene, free fatty acid and amino acid contents. G. changgi showed vitamin A activity of 865 mg rectinol equivalents/100 g sample. It contained a higher composition of unsaturated fatty acids (74%), mainly the omega fatty acids and 26% of saturated fatty acids (ma...

The nutritional significance of essential amino acids, as well as non-essential amino acids, is well documented in poultry production with regards to growth performance and protein accretion. However, the function of amino acids in the stress response is still unclear. L-Pipecolic acid, a L-lysine metabolite in the brain, induced a hypnotic and sedative effect acting via the γaminobutyric acid ...

In this study, the cDNA Growth Hormone (cGH) of the Belugasturgeon (Husohuso) and Russian sturgeon (Acipensergueldenstaedtii) were cloned and sequenced, and phylogenetic relationships were examined using nucleic acid and amino acid sequences. The nucleotide sequence of the Beluga GH has an open reading frame of 645 nucleotides encoding a protein 214 amino acid residues. The signal peptide cleav...

Abstract Bacteria produce diverse d-amino acids, which are essential components of cell wall peptidoglycan. Incorporation these acids into peptidoglycan contributes to bacterial adaptation environmental changes and threats. d-Amino have been associated with growth, biofilm formation dispersal regulation metabolism. The diversity in bacteria is primarily due the activities amino acid racemases t...

Animals rely on their diet for amino acids that they are incapable either of synthesizing or of synthesizing in sufficient quantities to meet metabolic needs. These are the so-called 'essential amino acids'. This set of amino acids is similar among the vertebrates and many of the invertebrates. Previously, no information was available for amino acid synthesis by the most primitive invertebrates...

Plant roots incorporate inorganic nitrogen into the amino acids glutamine, glutamic acid, asparagine and aspartic acid, which together serve as the primary metabolites of nitrogen transport to other tissues. Given the preponderance of these four amino acids, phloem sap is a nutritionally unbalanced diet for phloem-feeding insects. Therefore, aphids and other phloem feeders typically rely on mic...

The influence of first-pass splanchnic metabolism was investigated by comparing the response of 5 lactating cows to an infusion of an amino acid mixture into the abomasum or a jugular vein over 5 d according to a complete block design. The basal diet and the amino acid infusion provided 71% and 14% of crude protein requirements, respectively. The jugular infusion increased (P = 0.01) milk yield...

It has recently been reported (Howe, Unna, Richards, and Seeler (1)) that an amino acid mixture consisting largely of the essential amino acids in their natural form can be administered to dogs intravenously without gross ill effect at much faster rates than can a similar mixture which contains a larger proportion of racemic amino acids. Since the rapid administration of amino acids might resul...
