A representative CORM that has been extensively characterized both from a biochemical and pharmacological view point is the ruthenium(II) complex RuCl(CO) 3, known as CORM-3. Therapeutic data pertaining to metallic CORMs were reappraised to explore if observed effects are due to CO or if metal reactivity mediates physiological effects via thiol ...
As a result, a corm cut in half appears solid inside, but a true bulb cut in half reveals that it is made up of layers. [3] Corms are structurally plant stems, with nodes and internodes with buds and produce adventitious roots. On the top of the corm, one or a few buds grow into shoots that produce normal leaves and flowers.
A geophyte (earth+plant) is a plant with an underground storage organ including true bulbs, corms, tubers, tuberous roots, enlarged hypocotyls, and rhizomes. Most plants with underground stems are geophytes but not all plants that are geophytes have underground stems. Geophytes are often physiologically active even when they lack leaves.
The thin tunic leaves are dry papery, dead sheaths, formed from the leaves produced the year before. They act as a covering that protects the corm from insects and water loss. Internally a corm is mostly made of starch-containing parenchyma cells above a more-or-less circular basal node that grows roots. Corms are sometimes confused with true ...
Biophysical chemistry is a physical science that uses the concepts of physics and physical chemistry for the study of biological systems. [1] The most common feature of the research in this subject is to seek an explanation of the various phenomena in biological systems in terms of either the molecules that make up the system or the supra-molecular structure of these systems.

An overview of the different components included in the field of chemical biology. Chemical biology is a scientific discipline between the fields of chemistry and biology.The discipline involves the application of chemical techniques, analysis, and often small molecules produced through synthetic chemistry, to the study and manipulation of biological systems.

[4] [5] Plate tectonics are needed for life over a long time span, and carbon-based life is important in the plate tectonics process. [6] Iron- and sulfur-based Anoxygenic photosynthesis life forms that lived from 3.80 to 3.85 billion years ago on Earth produced an abundance of black shale deposits. These shale deposits increase heat flow and ...
Bioorganometallic chemistry is the study of biologically active molecules that contain carbon directly bonded to metals or metalloids. The importance of main-group and transition-metal centers has long been recognized as important to the function of enzymes and other biomolecules.
