Sulfur Assimilation01:20

Sulfur Assimilation

562
Sulfur is an essential element in biological systems, contributing to synthesizing key biomolecules, including amino acids such as cysteine and methionine, and cofactors such as coenzyme A and biotin. Microorganisms primarily assimilate sulfur as sulfate (SO₄²⁻) from the environment, which must undergo a series of biochemical transformations before it can be incorporated into cellular components. As sulfate is highly oxidized, it must undergo assimilatory sulfate reduction to...

Preparation and Reactions of Sulfides

4.4K
Sulfides are the sulfur analog of ethers, just as thiols are the sulfur analog of alcohol. Like ethers, sulfides also consist of two hydrocarbon groups bonded to the central sulfur atom. Depending upon the type of groups present, sulfides can be symmetrical or asymmetrical. Symmetrical sulfides can be prepared via an SN2 reaction between 2 equivalents of an alkyl halide and one equivalent of sodium sulfide.

Key Elements for Plant Nutrition02:35

Key Elements for Plant Nutrition

18.0K
Like all living organisms, plants require organic and inorganic nutrients to survive, reproduce, grow and maintain homeostasis. To identify nutrients that are essential for plant functioning, researchers have leveraged a technique called hydroponics. In hydroponic culture systems, plants are grown—without soil—in water-based solutions containing nutrients. At least 17 nutrients have been identified as essential elements required by plants. Plants acquire these elements from the...

Summary
This summary is machine-generated.

Dietary sulfur (S) negatively impacts selenium (Se) utilization and glutathione peroxidase activity in ewes. However, molybdenum (Mo) did not affect Se metabolism, suggesting S is a more significant dietary factor for Se bioavailability.

Area of Science:

  • Animal Nutrition
  • Trace Mineral Metabolism
  • Biochemistry

Background:

  • Selenium (Se) is an essential trace element crucial for antioxidant defense, primarily through glutathione peroxidase (GPx).
  • Dietary factors like sulfur (S) and molybdenum (Mo) can potentially interfere with Se absorption and metabolism.
  • Understanding these interactions is vital for optimizing animal health and productivity.

Purpose of the Study:

  • To investigate the effects of varying dietary concentrations of sulfur (S) and molybdenum (Mo) on selenium (Se) utilization in sheep.
  • To determine the impact of these minerals on tissue Se concentrations and GPx activity.
  • To elucidate potential antagonisms between S, Mo, and Se.

Main Methods:

  • Suffolk × Finn-Dorset ewes were fed diets with different concentrations of S or Mo.
  • Se concentrations and GPx activity were measured in various tissues.
  • Ewes were subjected to Se repletion and depletion protocols to assess mineral interactions.

Main Results:

  • A significant inverse relationship was observed between dietary S concentrations and Se levels in liver and wool.
  • Increased dietary S also led to decreased GPx activity in the liver, indicating S antagonism to Se.
  • Dietary Mo, within the tested ranges, had no significant impact on tissue Se concentrations or GPx activity.

Conclusions:

  • Dietary sulfur can antagonize selenium utilization and metabolism in sheep, particularly affecting liver and wool Se levels and GPx activity.
  • Molybdenum does not appear to interfere with selenium utilization in sheep at the tested dietary levels.
  • Ensuring adequate Se supply may mitigate the negative effects of sulfur on Se bioavailability in sheep.
