Supplementation of Nitrogen and its Influence on Free Sugars, Amino Acid and Protein Metabolism in Roots and Internodes of Wheat Effect of different doses of nitrogen (N) (90, 120, 150 and 180 kg Nha(-1)) on the activities of aminotransferases and alkaline inorganic pyrophosphatase (... As...
Tryptophan, an amino acid that is nutritionally important and occurs in small amounts in proteins. It is an essential amino acid, meaning that humans and certain other animals cannot synthesize it and must obtain it from their diets. Infants require grea
Protein Metabolism the sum of the processes of the transformation of proteins and the products of their decomposition—amino acids—in organisms. Protein metabolism is an essential part of metabolism. Since amino-acid metabolism is closely connected with the metabolism of other nitrogen compounds, prote...
First isolated in 1868 from legumin in plant seeds, aspartic acid is one of several so-called nonessential amino acids for mammals; i.e., they can synthesize it from oxaloacetic acid (formed in the metabolism of carbohydrates) and do not require dietary sources. The chemical structure of ...
An exocytotic fusion complex made from yeast SNARE proteins has similar properties, indicating that vesicle fusion occurs by similar mechanisms in yeast and human. Mutations that cause single amino acid substitutions in SNARE proteins that occur at residues in the core of the α-helix bundl...
A high index of suspicion in the setting of a degenerative demyelinating process and normal ASA enzyme levels leads to diagnosis, which can then be confirmed by the measurement of urine sulfatides, the assessment of sulfatide metabolism in cultured fibroblasts, or by direct sequencing of the gene ...
Engineering the regioselectivity of AmAT7-3 and the stereoselective mechanism of its mutants To further elucidate how adjacent amino acids contributed to the conformation of the xylosyl group (Xyl) and regulated the regioselectivity of AmAT7-3, we analyzed the complex structure of AmAT7-3/astragalosi...
Glycine, the simplest amino acid, obtainable by hydrolysis of proteins. Sweet-tasting, it was among the earliest amino acids to be isolated from gelatin (1820). Especially rich sources include gelatin and silk fibroin. Glycine is one of several so-called
Interactions between diet and gut microbiota are critical regulators of energy metabolism. The effects of fibre intake have been deeply studied but little is known about the impact of proteins. Here, we investigated the effects of high protein supplement
