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.

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

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

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

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.

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.

Subcategories include very low birth weight (VLBW), which is less than 1500 g (3 pounds 5 ounces), and extremely low birth weight (ELBW), which is less than 1000 g (2 pounds 3 ounces).

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.

Many of the most interesting proteins sought by molecular biologists are normally regulated to be expressed in very low amounts in wild type cells.

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.

The use of tobacco products or exposure to secondhand smoke during pregnancy has been linked to low birth weight.

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.

Jordan also claims an amount of USD 55,980,464 for other losses related to the increased incidence of low birth weight infants.

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

Trent engines use hollow titanium fan blades with an internal Warren girder structure to achieve strength, stiffness and robustness at low weight.

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.

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.

Birth factors such as low birth weight may also play a role as do a number of infectious diseases including HIV AIDS and tuberculosis.

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.

Large flash memory is currently more expensive than hard disk drives of similar size (as of mid 2014) but are starting to appear in laptop computers because of their low weight, small size and low power requirements.

For the pregnant women, anemia and malnutrition are some factors that lead to high incidence of premature childbirths, maternal mortality and low weight at birth.

Iraq questions the alleged link between the invasion and occupation of Kuwait and the increased incidence of low birth weight babies and malnourished children in Jordan.

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 primary causes of child deaths worldwide are pneumonia, followed by diarrhoea, low birth weight and prematurity, asphyxia at birth and, in some regions, malaria and HIV AIDS.

Well known, low cost, and low tech interventions do not reach those most in need for example immunization against tetanus, exclusive breastfeeding, simple care for low weight babies, and antibiotics for infection. Such interventions are extremely cost effective, and packaging these interventions together and linking them with other health programs reduces costs further.

Jordan claims an amount of USD 102,962,079 for expenses incurred in treating low birth weight infants and an amount of USD 51,710,096 for costs incurred in treating malnourished children.

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.
