What is the function of parietal cells in the stomach? What is the function of the rough and smooth endoplasmic reticulum inside of a cell? 1. Describe the function of the serous membrane. The layers and what they line or cover. 2. What are the types of serous membranes? 3. What does...
Cholesterol and cell membrane function: A hypothesis concerning the etiology of atherosclerosisThe presence of cholesterol has been shown to provide stability and, in general, to decrease the permeability of biological membranes to various solutes. Such stability would be beneficial to the cell only in...
These are a general class of macromolecules that are typically hydrophobic but can function in cell signalling, hormone production, energy sources, and coenzymes.Answer and Explanation: Cholesterol has many functions within the body, which are described below: Act as a precursor for steroids, inclu...

Spatial omics technologies can reveal the molecular intricacy of the brain. While mass spectrometry imaging (MSI) provides spatial localization of compounds, comprehensive biochemical profiling at a brain-wide scale in three dimensions by MSI with single
Cholesterol plays a key role in the molecular and mesoscopic organisation of lipid membranes and it is expected that changes in its molecular structure (e.g., through environmental factors such as oxidative stress) may affect adversely membrane properties and function. In this study, we present evi...
One of the parameters characterizing the membrane is the fluidity of the membrane, which depends on the chemical structure of phospholipids, including the degree of saturation of fatty acids, as well as the protein–lipid ratio and the presence of cholesterol in the membrane. The plasma membranes...
Analysis of the kinetics of cholesterol efflux from a number of different cell types has demonstrated the presence of slow and fast pools of cholesterol. The half-times (t1/2) for cholesterol efflux from these pools was similar with all cell types, howev
On the origin of sphingolipid/cholesterol-rich detergent-insoluble cell membranes: physiological concentrations of cholesterol and sphingolipid induce formation of a detergent-insoluble, liquid-ordered lipid phase in model membranes. Biochemistry 36, 10944–10953 (1997). Article CAS PubMed Google Scholar ...
Vesicles of phosphatidylcholine/cholesterol mixtures show a wide composition range with coexistence of two fluid phases, the 'liquid disordered' (cholesterol-poor) and 'liquid ordered' (cholesterol-rich) phases. These systems have been widely used as models of membranes exhibiting lateral heterogeneity ...
