Sentences with phrase «hydrophilic molecules»

Sublingual delivery of small, hydrophilic molecules such as NMN bypass the digestive system and can be quickly absorbed to the bloodstream making it far more bioavailable than capsules.

Meanwhile, the polymers, which exist in a watery solution, can carry hydrophilic molecules such as proteins, including antibodies and growth factors.

Not exact matches

The model system developed by researchers from the Jülich Centre for Neutron Science is made up of water and block copolymers — thread - like molecules with both a hydrophilic and a hydrophobic component.

If the hydrophilic component is large, only a few molecules will bundle themselves loosely together and their physical behaviour resembles that of threads.

A special feature of the model colloids made these findings possible: their softness can be tuned very finely over a large area by altering the length ratio between the hydrophilic and hydrophobic components of the molecule threads.

For example, hydrophilic polymers are often used to protect metals from fouling; water molecules accumulate on this polymer layer, which protects the metal against the adhesion of unwanted molecules or organisms.

They found it was the apparently random positioning of water - loving (hydrophilic) molecules in a protein that prevents water - hating molecules (hydrophobic, which possess the dominant folding force), from binding with other proteins.

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.

The outside of the doughnut, being hydrophilic, makes the molecule as a whole partially soluble in water.

Instead of a hydrophilic alcohol group (an oxygen - hydrogen molecule bound to a hydrogen - saturated carbon atom), the final lignin polymer contained a hydrophobic aldehyde group (a carbon atom double - bonded to an oxygen atom).

Since RNA is hydrophilic, or «likes water,» the molecules on the nanodiamond surface swell with excess hydration and weaken the heterogeneous dynamics of the molecules.

«The taste of whisky is primarily linked to so - called amphipathic molecules, which are made up of hydrophobic and hydrophilic parts.

Researchers at Osaka University overcame these limitations with fluorescent SM analogs by joining several fluorescent chemical compounds (fluorophores) that were highly hydrophilic to the hydrophobic lipid part (mainly acyl chains) of the synthetic molecule.

Vapor molecules run off the hydrophobic runways and coalesce into droplets at the hydrophilic nodes.

The researchers found that if the silica tends to have hydrophilic silanol groups on its surface, it attracts water molecules, in effect forming a «soft barrier» of water molecules that reactants would have to overcome to somehow penetrate to proceed with the desired process or reaction.

«It opens the doors to using hydrogen bonds to make surfaces hydrophilic, or attracted to water, and to (template) these surfaces for the selective absorption of other molecules possessing fundamental similarities to water,» Mavrikakis says.

The researchers believe that in hydrophilic materials, the attraction for water — a property known as «wettability» — makes water molecules more difficult to move, contributing to an increase in the fluid's effective viscosity.

Most surfactants, like soap molecules in bubbles and phospholipids in cellular membranes, have small water - loving (hydrophilic) heads and long fat - loving (hydrophobic) tails that determine how they arrange in space.

Lecithin is an emulsifier (used to keep fats / oils dispersed and in suspension): phospholipid molecules (such as lecithin) contain hydrophobic and hydrophilic elements; the hydrophobic portion has an affinity for fats and oils, and the hydrophilic portion has an affinity for water.
