long chains of atoms that are chemically joined to play many roles that we all love (organic solar cells) and hate (indestructible plastic pollution). Polymers are useful in liquid form as well: the difference

different chemical reactions in cells. The enzymes are of interest to biomedical, as well as bioenergy, researchers because of their role in metabolizing amino acids and other cell nutrients. “These enzymes

squalane, to create a model of the cell membranes of single-celled organisms called archaea. Archaea are a class of organisms, alongside bacteria and eukaryotic cells, that form the three main lineages ... similar function to cholesterol in human cells, led to the formation of clear internal structures – the first time such regions have been seen ...

human cells, which is one of the mechanisms reinforcing drug resistance. Essentially all human cells are covered with carbohydrate molecules (sugars) bound to the proteins and lipids embedded in cell membranes ... ions. Short animation showing a layer of lung epithelial cells with carbohydrates (sugars) on their surface. Pseudomonas aeruginosa ...

leaf at the surface of the wax compared to the bottom of the wax closest to the epicuticular plant cells – giving a lot of information regarding how the water is diffusing through the plant. D17 instrument

detector compared to use of the full white beam. Data collection is feasible for samples with unit-cell edges ranging from ~50 to 150 Å using crystal volumes from ~0.05 to 0.5mm3, respectively. For more

research has been carried out to understand the mechanism of IAPP-induced β-cell death. The concurrence of IAPP aggregation and cell depletion has developed the hypothesis that the aggregation is responsible ... through disrupting ionic homeostasis and thus inducing cell death. However, the precise biological mechanisms underpinning IAPP’s ...

electrode involves a cyclic transformation between two crystalline phases called α and β. These have unit (cell) volumes that differ by 20 per cent, which induces heavy constraints in the material and causes its ... different electrode materials. These experiments showed that a transitory intermediate γ phase with a cell volume between that of the ...

likely critical membrane fusion mechanism involved when the SARS-CoV-2 coronavirus infects human cells. SARS-CoV-2, the virus responsible for the COVID-19 pandemic, is from a family of single-stranded ... the fusion process) has not previously been conclusively identified. The Spike protein can mediate cell entry either via direct fusion at the ...

coli proteome unfolds at cell death provoking a striking dynamic slowdown and demonstrating the strong association between protein dynamics and bacterial metabolism and death. Cells are the building blocks ... within the cell and the activity of each is determined by how the protein is folded into a specific 3D structure. Though it was therefore ...
