The lipid habitats of neurotransmitter receptors in brain
(Elsevier Science, 2016-11)
Neurotransmitter receptors, the macromolecules specialized in decoding the chemical signals encrypted in the chemical signaling mechanism in the nervous system, occur either at the somatic cell surface of chemically excitable ...
Sex and reproductive cycle affect lipid and fatty acid profiles of gonads of Arbacia dufresnii (Echinodermata: Echinoidea)
(Inter-Research, 2016-06-09)
Analysis of the lipid composition of gonads allows differentiation between energy and structural lipids, which is important for understanding lipid utilization during gametogenesis. Fatty acids, which are frequently used ...
Lipídios estruturados: alternativa para a produção de sucedâneos da gordura do leite humano
(Sociedade Brasileira de Química, 2009)
Human milk has characteristics of great importance for the newborn. Its composition shows all nutrients in quantity and quality needed, in addition to providing protection against infections and allergies and stimulating ...
A structural appraisal of sterol carrier protein 2
(Elsevier Science, 2017-05)
Sterol Carrier Protein 2 (SCP2) has been associated with lipid binding and transfer activities. However, genomic, proteomic, and structural studies revealed that it is an ubiquitous domain of complex proteins with a variety ...
Correlation between the hydration of acyl chains and phosphate groups in lipid bilayers: Effect of phase state, head group, chain length, double bonds and carbonyl groups
(Elsevier Science, 2019-06)
This paper demonstrates by means of FTIR/ATR analysis that water molecules intercalate at different extents in the acyl chain region of lipid membranes in correlation with the hydration of the phosphate groups. This ...
Bordetella bronchiseptica glycosyltransferase core mutants trigger changes in lipid A structure
(Elsevier Science Inc., 2019-09-16)
Bordetella bronchiseptica, known to infect animals and rarely humans, expresses a lipopolysaccharide that plays an essential role in host interactions, being critical for early clearance of the bacteria. On a B. bronchiseptica ...
Ultrastructural detection of proteins, lipids and carbohydrates in oocytes of Amblyomma triste (Koch, 1844) (Acari; Ixodidae) during the vitellogenesis process
(Churchill Livingstone, 2007-06-01)
The ovary of the tick Ainblyomma triste is classified as panoistic, which is characterized by the presence of oogonia without nurse and follicular cells. The present study has demonstrated that the oocytes in all developmental ...
The chemopreventive activity of butyrate-containing structured lipids in experimental rat hepatocarcinogenesis
(2016-02-01)
Scope: Emerging evidence indicates that the use of bioactive food components is a promising strategy to prevent the development of liver cancer. The goal of this study was to examine the chemopreventive effect of ...
Disturbing Lipid Phase Equilibrium in Model Membrane Induced by Lytic Peptides
(2022-04-01)
Lytic peptides are rich in cationic and hydrophobic residues that form amphipathic α-helix when in contact with lipid bilayers. Evidence showed that they act on the lipidic phase of the cell membranes, inserting into the ...
Influence of particle size on the in vitro digestibility of protein-coated lipid nanoparticles
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2012)
The influence of particle size on the in vitro digestion of beta-lactoglobulin (BLG)-coated lipid nanoparticles was examined using simulated small intestine conditions. Nanoemulsions were prepared by high-pressure ...
