Sentences with phrase «lipid molecules»

We see this in hydrophobic and hydrophilic interactions that propel lipid molecules in water to corral together to form the two - layer membranes that serve as the coatings surrounding cells.

By using a novel set of photoactivatable lipid molecules, we are able to modulate the signalling underlying insulin secretion, likely to provide new means of identifying targets important in diabetes.

But other lipids are known to guide cell migrations in human brain development, and geneticist Ken Howard of University College London suspects HMG - CoA reductase might help produce a similar lipid molecule or modify a protein that attracts the germ cells.

The protein LecA on the surface of the bacteria binds to sugar on special lipid molecules, so - called Gb3 lipids, which are present in the outer membrane of human cells.

Because of this chemistry, lipid molecules arrange themselves with the fatty ends pointed toward each other, sandwiched between the water - loving ends pointed out.

Understanding why this complexity is required, how and when distinct lipid molecules interact with proteins and how these interactions are in turn modulated by lipid metabolism will be critical for elucidating how biological membranes function on a molecular level.

The Freiburg team of Shastri, Dr. Shengnan Xiang and Dr. Melika Sarem, have now discovered that liposomes — nanoscale vesicles of lipid molecules encompassing an aqueous core — can be used to alter the stiffness of the cell plasma membrane through lipid transfer.

New studies indicate that a specific type of lipid molecule plays a critical role in controlling the behavior of vesicles that store neurotransmitters within neurons.

Recently, researchers have begun to realize that the vernix also helps babies adapt to life outside the womb by stimulating cells in the skin to make water - resistant lipid molecules.

Modern lipidomics supplies a fully quantitative description of lipidomes down to the level of individual lipid molecules.

Using an RNA interference screen, Swanton and his colleagues identified a set of genes involved in the regulation of mitotic arrest and in the metabolism of ceramides, lipid molecules abundant in cell membranes that influence whether tumors are sensitive to certain chemotherapy agents.

The unsaturated lipid molecules of cell membranes are particularly susceptible to this damaging free radicals process and readily contribute to the uncontrolled chain reaction.

Use a facial oil cleanser or micellar water (which is made up water - soluble lipid molecules) to remove your make up.

Figure 1: Several reporter and modulator molecules have been developed in our lab, including: small molecule sensors for lipases and proteases; genetically encoded reporters for kinase and phosphatase activities; membranepermeant and photoactivatable lipid molecules; and lipid derivatives that can be fluorescently labelled in living cells.

A lipid molecule is a fatty molecule, insoluble in water, but soluble in fat solvents and alcohol — just like capsaicin.

So forget about your taste buds and concentrate on the binding of your lipid molecules!

Now I'm no scientist, but it seems to me that they are saying that the sensitivity to capsaicin is determined by genetics — some people's lipid molecules have a stronger bond with the capsaicin receptors than others.

Scientists Elizabeth D. Prescott and David Julius of the University of California, San Francisco, announced they had identified a lipid molecule called PIP2 that plays a crucial role in controlling the strength of the burning sensation caused by capsaicin.

In the mouth, there is a capsaicin receptor called TRPV1 and the lipid molecule PIP2 is bound to it.

Instead, lipid molecules are built from an array of building blocks whose combinations can change depending on the type of food we eat.

Biological membranes assemble from lipid molecules.

To create a better approach, Gradinaru, at the time a graduate student, and her colleagues in neuroscientist Karl Deisseroth's lab focused on replacing the tissue's lipid molecules, which make it opaque.

They discovered that a lipid molecule known as PIP2 is usually bound to the receptor, but in the presence of capsaicin, it is released, creating a painful sensation.

Lipid molecules made from unsaturated fatty acids on the other hand bear a kink in their chains, Min said, which makes it impossible for these lipid molecules to align closely with each other as saturated ones do.

The researchers explained that the stiff, straight, long chains of saturated fatty acids rigidify the lipid molecules and cause them to separate from the rest of the cell's membrane.

Under their microscope, the team observed that those lipid molecules then accumulate in tightly - packed «islands,» or clusters, that don't move much — a state they call «solid - like.»

To solve this enigma, the team focused on the behaviours of gangliosides: lipid molecules that were thought to play a central role in forming lipid rafts.

Gangliosides are lipid molecules that were proposed to play key roles in numerous biological processes, including the formation of raft domains, the entry of toxins into cells and chemical signal reception.

In one well - studied example, the bacteria called Campylobacter jejuni, a common cause of food poisoning, carries a lipid molecule on its outer coat that resembles so - called gangliosides, molecules that help human nerve cells recognize and communicate with each other.

The intestinal surface is like a toothbrush, with lots of grooves and protrusions that allow the cells there to grab and absorb nutrients from food as it is digested, including the lipid molecules from fatty foods.

Lipid molecules are long and mostly straight: They have a fatty end that prefers to hang out with other fats, and a water - like end that prefers the comfort of water.

They grab and absorb nutrients from food as it is digested, including the lipid molecules from fatty foods.
