THE data on the chemical composition of marine organisms are widely scattered; hence Prof. A. P. Vinogradov's paper on "La composition chimique 茅l茅mentaire des organismes marine" (Trav. Lab. Biog茅ochimigue, Acad,. Sci. URSS., Pt. 1, 1937, Pt. 2, 1941, Pt. 3, 1944) is a ...
Organisms regulate biogenic crystal properties for various functions. Here the authors reveal the genetic and biochemical control of crystal morphogenesis in zebrafish iridophores, showing that the chemical composition, influenced by enzyme expression, determines crystal morphology and functionality. ...
Seaweeds, named macroalgae, are an extensive group of macroscopic marine organisms that comprise a few thousand species (Kim et al., 2008; Kumari et al., 2010). According to the differences of their pigmentation, marine macroalgae are generally classified into three main phyla: Phaeophyta (brown...
Biomass is a renewable biological material made from recently alive or living organisms such as plants and animals. Biomass can be utilized to make biofuels such as biodiesel and ethanol and a source of energy. The composition and quality of biomass vary widely, especially in terms of moisture, ...
In general, MNBs are negatively charged at various pH conditions as indicated by their zeta potential However, the surface charge of MNBs can be modified by the surrounding environment's composition, providing the opportunity for fine-tuning their properties for optimal performance in different ...
This article provides information about the Chemical Composition of Nucleus!The nucleus contains mainly nucleoproteins composed of nucleic acid and proteins, besides enzymes and inorganic salts.The following is the percentage of different components of nucleus of mammalian liver cells in interphase, ...
Many aquatic organisms possess well-developed chemosensory systems that are adapted to monitoring changes in the chemical composition of the aqueous environment in which they live. For aquatic organisms. specific chemicals in the environment may evoke highly predictable changes in behavior. Facets of beha...
Plant metabolism of nematode pheromones mediates plant-nematode interactions Small molecules in the rhizosphere regulate interactions between plants and other organisms. Here the authors show that an ascaroside pheromone secreted by plant-parasitic nematodes is converted by host plant peroxisomal β-oxidati...
Ediacaran Cloudina and Namacalathus, which are among the earliest shell-forming organisms, originally produced aragonitic skeletons, which later underwent diagenetic conversion to calcite42. Crystals of aragonite have been also revealed within Codiacean algae43, which means that the origin of aragonite ...
Potassium is important for the functioning of organisms and is consequently found in all human and animal tissues, specifically plant cells. The whole amount of potassium in the human body is between 110-one hundred forty grams. It's miles critical for human features consisting of coronary heart...
