Molecules

So while the heart pumps blood it also makes the same molecules: dopamine, serotonin, oxytocin, opiates, and what I referred to as the molecules of emotion. ❋ Unknown (2010)

Hassel from Oslo for developing the concept of conformation, i.e. the spatial arrangement of atoms in molecules, which differ only by the orientation of chemical groups by rotation around ❋ Unknown (2010)

Dipole moments are found in molecules, in which the positive and negative charge is unevenly distributed (polar molecules). ❋ Unknown (2010)

Svedberg's student, Arne Tiselius, studied the migration of protein molecules in an electric field, and with this method, named electrophoresis, he demonstrated the complex nature of blood proteins. ❋ Unknown (2010)

In addition, contact with cells by molecules from the invading organism like PAMPs (pathogen associated molecular patterns) stimulate production and release of more AMPs. ❋ Grrm (2010)

The use of chemistry to build biologically useful molecules is a form of engineering, so I did not escape the tradition set up by my father, uncles, and brothers. ❋ Unknown (2009)

This last bit is made of a metal-organic framework that can apparently absorb carbon dioxide and water molecules from the air. ❋ Unknown (2010)

Today, GFP is widely used as a fluorescent marker of protein molecules and cells, and it is an essential tool in the study of biology, physiology, and medicine. ❋ Unknown (2009)

As Zachriel has pointed out, there are certain molecules that are always found in living organisms, either as structural material or carrying out particular functions (AFAWCTGTETD). ❋ Unknown (2009)

On the ribosome, these transfer RNA molecules recognize the code words in messenger RNA for their own amino acid and, thus, the ribosome factory links the amino acids together in the sequences prescribed by the blueprints for proteins. ❋ Unknown (2009)

In sickle cell disease, hemoglobin molecules under certain conditions aggregate to form polymers, which in turn cause distortion of red blood cells. ❋ Unknown (2010)

Adding acidic wine to the mixture prevents this by surround the casein molecules with hydrogen ions, charging them so they repel each other. ❋ Ewillett (2008)

A pool of exclusively ‘right-handed’ ribose molecules is generated and separated from other sugars as a result of what selection principle? ❋ Unknown (2008)

A pool of exclusively ‘right-handed†™ ribose molecules is generated and separated from other sugars as a result of what selection principle? ❋ Unknown (2008)

If self-replicating RNA molecules is what you have in mind then fidelity can be defined at one level as the sequence specificity needed for molecular replication. ❋ Unknown (2008)

Cooked meat is easier to eat because the heat alters the protein molecules in the meat. ❋ Ewillett (2008)

Heat breaks these bonds, allowing the protein molecules to unwind. ❋ Ewillett (2008)

Radioisotopes can therefore be used to label molecules of biological samples in vitro (out of the body). ❋ Unknown (2009)

Writing in the journal Nature Biotechnology, the researchers explain how an enzyme found in fungi can be used as a kind of biological scissors to cut sugar molecules from the surface of red blood cells. ❋ Unknown (2007)
