Extraction of Fucoidan from Turbinaria decurrens and the
Brown seaweeds usually contain alginate as a major polymer. The second major sulfated polymer in brown seaweeds is fucoidan, which has huge potential in medicinal applications. In this study, the photosynthetic pigments from Turbinaria decurrens were first extracted using chloroform/methanol in the ratio of 1:1 (v/v), followed by fucoidan extraction
Natural rubber is perhaps the most important and plentiful sustainable rubber that has been exploited by humankind over a span of more than 300 years. Natural rubber essentially is a hydrocarbon, whose constitution was established by Michael Faraday in 1826. Chemically, the rubber hydrocarbon unit is composed of cis-1,4-polyisoprene [(C 5 H 8) n].
Acetylcysteine C5H9NO3S PubChem
Acetylcysteine is a synthetic N-acetyl derivative and prodrug of the endogenous amino acid L-cysteine, a precursor of the antioxidant glutathione (), with mucolytic, antioxidant, and potential cytoprotective, cancer-preventive, and anti-inflammatory activities.Upon administration, acetylcysteine exerts its mucolytic activity by reducing disulfide bonds in mucoproteins,
Introduction. Castor oil has long been used commercially as a highly renewable resource for the chemical industry.1,2 It is a vegetable oil obtained by pressing the seeds of the castor oil plant (Ricinus communis L.) that is mainly cultivated in Africa, South America, and India.3,4 Major castor oil-producing countries include Brazil, China, and India. . This oil is
Molecular Basis for the Substrate Promiscuity
Appropriate controls were conducted to account for any ATPase activity. Each reaction consisted of 2 U PK, 2 U LDH, 0.6 mM NADH, 1.5 mM PEP, 2 mM ATP, and 4 μg of IPK incubated in a buffered solution (25 mM Tris pH 7.8 and 5 mM MgCl 2). All positive reactions were verified using high-resolution mass spectrometry (HRMS).
N-Phenyl-1-naphthylamine is used as an antioxidant in gear, hydraulic, lubrication, and bearing oils and as a protective agent and antioxidant in rubbers and rubber mixtures. International Programme on Chemical Safety's Concise International Chemical Assessment Documents. Number 9: N-Phenyl-1-naphthylamine (1998).
