(Spiewoket al., 2006). Extracts from gynes, workers, and drones contained exclusively cuticular lipids, and the profile from gynes was much more diverse than that of workers and drones; the most striking differences related to the alkenes, monomethyl- and dimethylalkanes suggested a potential ...
When mixed with water, phospolipids spontaneously form membranes because the tails are hydrophobic (don't like water) and the heads are hydrophillic (like water because slightly polar). This causes the tails to move inside the layer and the heads to be on the outside. Why do phospholipids...
Lipidscontain carbon, hydrogen, and oxygen, just like carbohydrates, but they have more hydrogen than oxygen. Lipids contain substances such as waxes, steroids, fats, and phospholipids. They do not dissolve in water, which means they are considered 'hydrophobic' (not water-soluble)....
lipids, depending on their solubility in lipophilic and hydrophilic environments. Furthermore, the question of whether compounds such as AA and PPs are active within the CNS also depends on their compartmentalization between the cerebrospinal fluid (CSF), extracellular fluid (ECF) and the different ...
While lipids are essential components of cell membranes, they mostly lack a direct link to the input signals. Here we review how proteins can deform locally membranes, modify and reorganise lipids to form membrane domains and regulate properties like membrane charges and diffusion. From this point...
Chylomicron lipoprotein aggregates are used to transport lipids in the blood because ___. (a) lipids are insoluble in water (b) long-chain fatty acids get tangled together and clot (c) blood can only transport globular-shaped objects (d) lipids cannot Beta-...
The researchers discovered that the larvae of one tubeworm species contain enough stored energy, in the form of lipids, to survive for 30 to 40 days. Some larvae had hairlike cilia for swimming, but those wouldn't take the tiny larvae very far. They needed to get swept into big ocean ...
How do fish fins come into being and how do fins evolve into terrestrial tetrapod limbs? To answer this scientific question is substantially to understand how the genes that determine these traits are subject to natural and sexual selection, and how they thereby involve the innovation mechanics and...
aS is the main constituent of Lewy bodies (LBs), which are inclusions composed of proteins and lipids found in PD brains14. Mutations in the aS gene and gene multiplications are associated to inherited PD forms15. The physiolog- ical function of aS has been associated with neurotransmitter ...
Can bacteria reproduce both sexually and asexually? Bacteria Reproduction. Just like any other organism, bacteria also reproduce to continue their species. Since they are unicellular and do not have a well-organised cell, bacteria have been grouped under prokaryotes. However,they do show both sexual...
