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

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

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

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

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

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.

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.

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.

Fortunately, fluorine consists of only a single isotope 19F, so that the 1 difference in molecular weights between 235UF6 and 238UF6 is due only to the difference in weights of the uranium isotopes.

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.

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.

According to Jordan, malnutrition in pregnant women resulted in an increase in the incidence of low birth weight infants.

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.

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.

It s very hard to explain this by molecular recognition.

The mean molecular mass of air is 28.97 g mol.

However, the Panel notes that there is some evidence of an increase in the incidence of low birth weight infants in Jordan immediately following Iraq's invasion and occupation of Kuwait, and that this increase could have been partly due to the arrival of pregnant refugee women who delivered low birth weight infants while in Jordan.

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.

The excited molecular nitrogen (atomic nitrogen being rare due to high stability of the N2 molecule) plays its role here as well, as it can transfer energy by collision to an oxygen atom, which then radiates it away at the green wavelength.

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

Sami lost weight.

Indeed, the impact of intelligence on mortality rivals well known risk factors for illness and death, such as high blood pressure, being overweight, high blood glucose, and high cholesterol.

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

The quality of the sample is sufficient for research on molecular biology.

In contrast, molecular orbital theory has orbitals that cover the whole molecule.

And for molecular programming, the question is how does your cell phone know when to stop growing?

He believed the rays to consist of streams of particles of ordinary molecular magnitude.

Restart the treatment, loses the weight again.

Atmosphere The outer atmosphere of Saturn contains 96.3 molecular hydrogen and 3.25 helium by volume.

Significant weight loss is a bad sign.

Mayweather had such difficulty making weight for this fight that he did not eat for four days before the weigh in.

Jordan contends that the increases in low birth weight infants and malnourished children would not have occurred but for the increase in its population caused by the influx of refugees into the country, which was a direct result of Iraq's invasion and occupation of Kuwait.

Resistance to the growing influence of molecular biology was especially evident in evolutionary biology.

Maybe you should lose some extra weight.

Maybe you should lose some extra weight.

Reducing the proportion of under weight births.

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

Biology and molecular biology Almost all forms of biophysics efforts are included in some biology department somewhere.

The height of the root is the height of the tree.

In children, a healthy weight varies with age and sex.

And observe correct measure , weigh with justice , and not cheat the balance .

And establish the measures justly , nor decrease the due weight .

and weigh with justice , and skimp not in the Balance . )

And observe the weight with equity , and make not deficient the balance .
