AMINO ACID METABOLISM IN OSTEOPOROSIS
Journal of the American Geriatrics Society, 1970A bstract : To evaluate amino acid metabolism in osteoporosis, the effects of oral loading with an amino acid mixture were studied in 11 aged patients with advanced osteoporosis, 5 aged patients with mild osteoporosis, and 7 healthy aged subjects (controls)

Anaerobic Amino Acid Metabolism
Russian Journal of Plant Physiology, 2003Anoxic stress induces a strong change in sugar, protein and amino acid metabolism in higher plants. Sugars are rapidly consumed through the anaerobic glycolysis to sustain energy production. Protein degradation under anoxia is a mechanism to release free amino acids contributing in this way in maintaining the osmotic potential of the tissue under ...

Amino acid metabolism in chameleons
Comparative Biochemistry and Physiology, 1968Abstract 1. 1. In general non-essential amino acids were catabolized more rapidly by the intact chemeleon than essential amino acids. 2. 2. Body glycine and glutamine increased after the injection of most amino acids. 3. 3. Amino acid interconversions observed resembled those reported for other animals. 4. 4.

Amino Acid Metabolism and Fluxes
EcoSal Plus, 2008By the mid1960s, the pioneering work of Umbarger and Gerhart and Pardee had shown us that carbon flow through a biosynthetic pathway was controlled by allosteric inhibition of the first enzyme of the pathway by its end product; and, studies of the lac operon by Jacob and Monod had established that genes were ...

Metabolism of the Aromatic Amino Acids
1955Publisher Summary The chapter discusses the metabolism of phenylalanine, tyrosine, and tryptophan. Phenylalanine acid tryptophan is “essential” amino acids for higher organisms— that is, they cannot be synthesized by the organism and must be supplied in the diet. Tyrosine, formed from phenylalanine acid is not essential if the phenylalanine intake is

Metabolic Labeling with Amino Acids
Current Protocols in Cell Biology, 1998AbstractMetabolic labeling techniques are used to study the biosynthesis, processing, intracellular transport, secretion, degradation, and physical‐chemical properties of proteins. This unit provides protocols for metabolic labeling of cells with [35S]‐labeled amino acids to provide material suitable for analysis by immunoprecipitation, for ...

Annual Review of Biochemistry, 1975
Much of the interest in amino acid metabolism has centered on the intermediary steps involved in catabolism, the regulation of biosynthesis and transport, and genetic disorders resulting in abnormal urinary and/or plasma concentrations of amino acids. This review will focus on recent studies in which amino acid exchange between various organs has been ...

Amino Acid Metabolism in Helminths
1991Amino acids are major constituents of biological material. Chemically they are extremely stable and combine a relatively simple molecular structure with a wide range of properties and functions. In general, amino acid metabolism in helminths has been relatively neglected and the information available is often uneven and of uncertain quality.
