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.

Development of the Potential Distribution Theorem (PDT) allows this complex subject to be simplified to down to earth presentations of molecular theory.

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

Molecular epidemiology is a branch of epidemiology and medical science that focuses on the contribution of potential genetic and environmental risk factors, identified at the molecular level, to the etiology, distribution and prevention of disease within families and across populations.

In this variant, all three existing factors are retained, but with a different weight distribution from the current one.

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.

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

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.

(a) Changes to geographical distribution by varying the weight of the membership, population and contribution factors while holding the base figure constant at the current level of 2,700

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.

Varying the weight of the membership, population and contribution factors within the limits of the existing base figure constitutes the most common method of adjusting the geographical distribution of posts.

The hyperbolic distribution The hyperbolic secant distribution The Johnson SU distribution The Landau distribution The Laplace distribution The Lévy skew alpha stable distribution or stable distribution is a family of distributions often used to characterize financial data and critical behavior the Cauchy distribution, Holtsmark distribution, Landau distribution, Lévy distribution and normal distribution are special cases.

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 weight of the factors taken into account for the distribution of geographical posts remains at 55 per cent for contribution, 40 per cent for membership and 5 per cent for population.

Options for changes in the number and weight of the factors for equitable geographical distribution have been undertaken in a number of studies by the Secretariat at the request of the General Assembly.

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 !
