Key Elements for Plant Nutrition02:35

Key Elements for Plant Nutrition

18.9K
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...

Drug Concentrations: Measurements01:23

Drug Concentrations: Measurements

426
Drug concentration is the quantity of a drug present in a biological sample. Measuring drug amounts in biological samples allows the clinician to understand how a drug is absorbed, distributed, metabolized, and excreted. Samples can be obtained through invasive or non-invasive methods. Invasive techniques involve surgical or parenteral interventions to gather blood, cerebrospinal fluid, or tissue biopsy. Conversely, non-invasive approaches provide samples like urine, feces, and saliva.

Physiological Pharmacokinetic Models: Assumption with Protein Binding

77
Physiological models with protein binding in pharmacokinetics offer a sophisticated approach to understanding drug disposition. These models consider drug-protein interactions, enabling them to effectively predict drug concentrations in different organs and tissues. This precision aids in accurate drug dosing, providing a significant advantage over conventional models. A key process within these models is equilibration, which ensures that drug concentrations achieve a steady state within the...

Expressing Solution Concentration

59.2K
A solute is a component of a solution that is typically present at a much lower concentration than the solvent. Solute concentrations are often described with qualitative terms such as dilute (of relatively low concentration) and concentrated (of relatively high concentration).
Concentrations may be quantitatively assessed using a wide variety of measurement units, each convenient for particular applications. Molarity (M) is a useful concentration unit for many applications in chemistry.

Mineral, Vitamin and Water Absorption

561
Electrolytes are essential minerals and ions primarily obtained from the diet and absorbed through the gastrointestinal tract. Most electrolytes are absorbed in the small intestine. While the absorption of iron and calcium primarily occurs in the duodenum, calcium is also absorbed in the jejunum and ileum. In these regions, passive diffusion contributes to its absorption alongside active transport mechanisms in the duodenum. These ions can exit the enterocytes through specialized active...

Compounds Essential to Human Function

6.0K
The human body is composed of cells that are fundamentally made up of several different molecules. These molecules are essential to carry out all physiological processes in the body and are broadly classified into organic and inorganic based on their chemical structures.
Inorganic Compounds Essential to Human Functioning
Inorganic compounds essential to human functioning include water, salts, acids, and bases. These compounds are inorganic, i.e., they do not have a carbon-hydrogen bond. Water...

Area of Science:

  • Nutritional science
  • Biochemistry
  • Food science

Background:

  • Global programs aim to measure and catalog food composition.
  • Understanding nutrient variability is crucial for food databases and health impact assessments.

Purpose of the Study:

  • To analyze the nutrient content of the entire US food supply.
  • To identify universal patterns in nutrient concentration variability.
  • To explore the biochemical basis of observed nutrient scaling laws.

Main Methods:

  • Analysis of comprehensive US food supply nutrient data.
  • Application of single-parameter scaling law analysis.
  • Investigation of metabolic pathway constraints on nutrient modulation.

Main Results:

  • A universal single-parameter scaling law governs nutrient concentrations across the food supply.
  • This law accurately describes nutrient variability over eight orders of magnitude.
  • The universality is explained by biochemical constraints in metabolic pathways.

Conclusions:

  • Natural nutrient variability in food can be quantitatively formalized.
  • The findings provide a mathematical basis for imputing missing data in food composition databases.
  • This research offers insights into food processing effects on nutrient balance and health.
