Gel permeation chromatography is used to determine the number average molecular weight, weight average molecular weight, and polydispersity.

It has the molecular formula C14H14N2.HCl and a molecular weight of 246.73 g mol.

Many higher molecular weight amines are, biologically, highly active.

Each has a molecular weight of approximately 50,000 Daltons.

Lighter molecules move faster than heavier ones with the same thermal kinetic energy, and so gases of low molecular weight are lost more rapidly than those of high molecular weight.

And I thought molecular weight sounded much less nerdy than molar mass.

A molecular sieve can adsorb water up to 22 of its own weight.

However, it was difficult to determine the exact molecular weight and number of amino acids in a protein.

Separation of proteins may be by isoelectric point (pI), molecular weight, electric charge, or a combination of these factors.

The combination is theoretically useful because it results in good removal of both large and small molecular weight solutes.

A key difference compared to other biogeochemical cycles is that because of its low molecular weight hydrogen can leave Earth's atmosphere.

High temperature, oxygen concentration and low pH degrade 11 S storage proteins of green coffee beans to low molecular weight peptides and amino acids.

And then afterward, I said, Sir, I want to give you the periodic table in case you're ever in a bind and need to calculate molecular weight.

I had a similar experience when I was working in his lab, trying to isolate the first inhibitors of blood vessel growth (which were large molecular weight substances).

Proteins are separated according to isoelectric point (pH at which they have neutral net charge) in the first dimension, and according to their molecular weight in the second dimension.

In this way Einstein was able to determine the size of atoms, and how many atoms there are in a mole, or the molecular weight in grams, of a gas.

This method only gives a rough measure of the amounts of different proteins in the mixture, and it is not able to distinguish between proteins with similar apparent molecular weight.

As xenon is expensive, the gas sulfur hexafluoride, which is similar to xenon in molecular weight (146 versus 131), is generally used in this stunt, and is an asphyxiant without being anesthetic.

Surgeons are taught from textbooks which conveniently color code the types of tissues, but that's not what it looks like in real life until now. At TEDMED Quyen Nguyen demonstrates how a molecular marker can make tumors light up in neon green, showing surgeons exactly where to cut.

An understanding of statistical thermodynamic molecular theory is fundamental to the appreciation of molecular solutions.

Granule position 64 bits A granule position is the time marker in Ogg files.

It is a major marker to assess the quality of health care delivery.

Molecular basis for inheritance DNA and chromosomes The molecular basis for genes is deoxyribonucleic acid (DNA).

This method is used in the fields of molecular biology, immunogenetics and other molecular biology disciplines.

Molecular motors are biological molecular machines that are the essential agents of movement in living organisms.

The nearly neutral theory of molecular evolution is a modification of the neutral theory of molecular evolution that accounts for slightly advantageous or deleterious mutations at the molecular level.

The items visible at the current time marker are displayed in the Composition Panel.

Given that tumors take several months to grow, biocompatible systems had to be developed that could release proteins and other large molecular weight substances slowly and continuously in the body something that scientists were convinced was impossible.

Molecular physics is the study of the physical properties of molecules, the chemical bonds between atoms as well as the molecular dynamics.

The feedstock to an FCC is usually that portion of the crude oil that has an initial boiling point of 340 C or higher at atmospheric pressure and an average molecular weight ranging from about 200 to 600 or higher.

So now, all of this indicates that there are molecular programs underlying biology, and it shows the power of molecular programs biology does.

It's a molecular computer building an electronic computer.

It has the molecular formula Al(OH)2C18H35O2.

The marker of his burial place was removed in modern times when a railway was built over his grave.

Again of course that's what we do, both in a molecular way, and also in an outward way, but I think about the molecular stuff.

It's a great time to be a molecular biologist.

If we succeed, what will molecular programming look like?

It s very hard to explain this by molecular recognition.

This is done both on a microscopic and molecular level.

She was considered one of the world's leading molecular geneticists.

The mean molecular mass of air is 28.97 g mol.

We shall surely attend to you at leisure , you weight and you weight !

We shall surely attend to you at leisure , you weight and you weight !

The loss of protein in the urine is regarded as an independent marker for worsening of renal function and cardiovascular disease.

Sami lost weight.
