3-Aminobutanoic acid or β-Aminobutyric acid (BABA) is an isomer of the amino acid aminobutyric acid with the chemical formula C4H9NO2. It has two isomers, α-aminobutyric acid and γ-aminobutyric acid (GABA), a neurotransmitter in animals that is also found in plants, where it may play a role in signalling. All three are non-proteinogenic amino acids, not being found in proteins. BABA is known for its ability to induce plant disease resistance, as well as increased resistance to abiotic stresses, when applied to plants.
3-Aminobutanoic acid applied as a foliar spray causes the plant hormone salicylic acid (SA) to accumulate, which is a key hormone in controlling systemic acquired resistance (SAR). Genetically modified tobacco plants that are unable to accumulate SA are still protected by BABA against some pathogens, but not others, indicating pathosystem-specific mechanisms by which BABA confers resistance. Arabidopsis unable to produce SA, jasmonic acid or ethylene (other hormones involved in defence) were still protected from the oomycete Peronospora parasitica but plants unable to produce SA were susceptible to the bacteria Pseudomonas syringae. This variation in the hormones required for BABA to confer resistance makes it differ from other synthetic activators of plant defence, which only operate through the SAR pathway of PR proteins.
Barium thiosulfate is a chemical compound with diverse applications, including its use in medical imaging as a contrast agent, in chemical reactions as a reagent, and in environmental applications like wastewater treatment. It also plays a role in the production of barium-based pigments and potentially in agricultural soil amendment.
Here 's a more detailed look at its importance:
1. Medical Imaging:
Barium thiosulfate, along with its more commonly used counterpart barium sulfate, is utilized as a contrast agent in medical imaging, particularly for the digestive tract (gastrointestinal imaging).
It absorbs X-rays, making the areas where it 's present appear white or light on X-ray images, allowing for visualization of the digestive tract.
Barium sulfate, being insoluble, is preferred over barium thiosulfate in medical imaging due to its reduced risk of systemic absorption and toxicity.
2. Chemical Applications:
Barium thiosulfate serves as a reagent in various chemical reactions and analyses.
It 's a standard for thiosulfate iodometry, used to determine the concentration of specific metal ions in solution, such as molybdenum.
It can act as a reducing agent in analytical chemistry and environmental applications.
3. Environmental Applications:
Barium thiosulfate is used in wastewater treatment to neutralize harmful sulfates, contributing to pollution control.
It can be a component in the synthesis of other barium compounds.
Monobenzone, also called 4-(Benzyloxy)phenol and monobenzyl ether of hydroquinone (MBEH) Depigmentation Monobenzone, also known as MBEH or Benoquin, is a topical medication used primarily for the permanent depigmentation of normal skin surrounding vitiligo patches in individuals with extensive vitiligo (affecting over 50% of the body surface area). It 's a derivative of hydroquinone and works by causing the destruction or inhibiting the function of melanocytes, the cells that produce skin pigment. Here 's a more detailed explanation:What it is: Monobenzone is a chemical compound, specifically the monobenzyl ether of hydroquinone, and is a topical medication Important considerations: Permanence:The depigmentation effect of monobenzone is generally considered permanent. Extensive vitiligo:Monobenzone is typically used for individuals with widespread vitiligo where depigmenting the remaining normal skin is a suitable approach.
Diallyl Bisphenol A (DABA) is a modified monomer used to enhance the properties of thermosetting resins like bismaleimide, epoxy, and phenolic resins. It improves toughness, heat resistance, and can act as an active diluent, reducing the curing temperature of resins. It also improves adhesion in rubber applications. Here 's a more detailed breakdown:
Modified Monomer:DABA is a derivative of Bisphenol A (BPA) where the hydrogen atoms on the aromatic ring are replaced with allyl groups.
Resin Modification:It 's primarily used to modify thermosetting resins, including:
Bismaleimide (BMI) resins: DABA enhances toughness, reduces cost, and improves heat resistance and moldability.
Epoxy resins: DABA can improve toughness, thermal stability, flexibility, bonding properties, mechanical properties, solvent resistance, and workability.
Phenolic resins: DABA can be used to modify and toughen these resins as well
