Metabolic rift is a theory of ecological crisis tendencies under the capitalist mode of production that sociologist John Bellamy Foster ascribes to Karl Marx. Quoting Marx, Foster defines this as the "irreparable rift in the interdependent process of social metabolism ".
Lipid raft organization, region (1) is a standard lipid bilayer, while region (2) is a lipid raft. The plasma membranes of cells contain combinations of glycosphingolipids, cholesterol and protein receptors organized in glycolipoprotein lipid microdomains termed lipid rafts.
Accommodation zones may be located where older crustal structures intersect the rift axis. In the Gulf of Suez rift, the Zaafarana accommodation zone is located where a shear zone in the Arabian-Nubian Shield meets the rift. [6] Rift flanks or shoulders are elevated areas around rifts. Rift shoulders are typically about 70 km wide. [7]
Coacervate droplets dispersed in a dilute phase. Coacervate (/ k oʊ ə ˈ s ɜːr v ə t / or / k oʊ ˈ æ s ər v eɪ t /) is an aqueous phase rich in macromolecules such as synthetic polymers, proteins or nucleic acids.
Biogeochemistry research groups exist in many universities around the world. Since this is a highly interdisciplinary field, these are situated within a wide range of host disciplines including: atmospheric sciences, biology, ecology, geomicrobiology, environmental chemistry, geology, oceanography and soil science.
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.

In chemistry, de novo synthesis (from Latin 'from the new') is the synthesis of complex molecules from simple molecules such as sugars or amino acids, as opposed to recycling after partial degradation. For example, nucleotides are not needed in the diet as they can be constructed from small precursor molecules such as formate and aspartate.
Reactive nitrogen species (RNS) are a family of antimicrobial molecules derived from nitric oxide (•NO) and superoxide (O 2 •−) produced via the enzymatic activity of inducible nitric oxide synthase 2 and NADPH oxidase respectively.
