The metabolism of amino sugars [PDF]
The incorporation and distribution of radioactivity from 1-14C-D-glucosamine, N-acetyl-1-14C-D-glucosamine and 1-14C-N-acetyl-D-glucosamine in growing cultures of Bacillus subtilis NCTC 1379 has been investigated. The radioactivity from N-acetyl-1-14C-D-glucosamine is incorporated rapidly and the rate of incorporation is proportional to the external ...

Chiral Sugars Drive Enantioenrichment in Prebiotic Amino Acid Synthesis [PDF]
Chiral pentose sugars mediate the enantioselective synthesis of amino acid precursors, with the magnitude of the chiral induction dictated by a subtle cooperativity between sugar hydroxyl groups.

Biochemical Changes During Seed Germination of Sterculia urens Roxb.
The present study describes biochemical changes taking place during seed germination of Sterculia urens. The levels of proteins, total amino acids, reducing sugars, total soluble sugars and lipids were studied during various stages of seed germination (0-

Effects of nitrogen and sulfur fertilization on free amino acids, sugars, and acrylamide-forming potential in potato [PDF]
Nitrogen (N) fertilizer is used routinely in potato (Solanum tuberosum) cultivation to maximize yield. However, it also affects sugar and free amino acid concentrations in potato tubers, and this has potential implications for food quality and safety ...

Soil Microbial Populations Shift as Processes Protecting Organic Matter Change During Podzolization
In the upper part of the solum of mineral soils, soil organic and mineral constituents co-evolve through pedogenesis, that in turn impacts the transformation and stabilization of soil organic matter (SOM).

Effects of water availability on free amino acids, sugars, and acrylamide-forming potential in potato [PDF]
Irrigation is used frequently in potato cultivation to maximize yield, but water availability may also affect the composition of the crop, with implications for processing properties and food safety. Five varieties of potatoes, including drought-tolerant

Sources of total, non-milk extrinsic, and intrinsic and milk sugars in the diets of older adults living in sheltered accommodation [PDF]
The WHO recommends limiting non-milk extrinsic sugars (NMES) consumption to ≤ 10 % energy to reduce the risk of unhealthy weight gain and dental caries, and to restrict frequency of intake to ≤ 4 times/d to reduce risk of dental caries.
