When two or more atoms link up, they createa molecule . A molecule of water is made of two atoms of hydrogen (H) and one atom of oxygen (O). The molecular mass is the sum of the masses of all the atoms in the molecule. A collection of molecules is called a compound. ...

Arla Cravendale is launching 'It's Not Milk', anew advertising campaign created by Wieden+Kennedy London, celebrating that not all milk is created equal. ... Emma Stanbury, at Arla Cravendale, said: “The new campaign celebrates what makes Arla Cravendale a cut above; that it's filtered for...
Examining how a molecule responds to light on extremely fast timescales allows researchers to track how electrons move during a chemical reaction. "The big question is how a molecule dissipates energy without breaking apart," said Enrico Ridente, a physicist at Berkeley Lab and lead author on the...
"Sandwich" immu- nosensors waste time and energy compared to the "label-free" type, in which the electrochemical signal molecule is immobilized on the electrode or dissolved in an electrolyte in only one step to detect the target7,8. Therefore, it is more desirable to construct "label-...
where C is carbon, H is hydrogen, O is oxygen and each hyphen is a chemical bond between the atoms. For clarity, the bonds of the three hydrogen atoms to the left carbon atom are not shown. The OH (O - H) group on the molecule is what makes it an alcohol. There are four types...
He built a molecular spring by stringing 12 carbon atoms together and attaching a vitamin B12 molecule to each end of the chain by means of a cobalt atom. In the relaxed state the chain has a zigzag shape; when it is wetted with water, however, it kinks tightly together. Adding ...
They begin to tangle and mix until the substance is less like the liquid you started with and thicker and rubberier like slime! Picture the difference between wet spaghetti and leftover spaghetti the next day. As the slime forms the tangled molecule strands are much like the clump of ...
Is serine a monomer or macromolecule? Many carbohydrate names end with “ose”. Proteins are molecules made of a monomer calledamino acids. Examples of amino acids: serine, tryptophan, leucine. Is serine charged? Six amino acids have side chains that are polar butnot charged. These are serine...
DNA is a molecule like a recipe for life and holds all the information your body needs to function. Pretty crazy! Even more amazing is that just a teeny, tiny percent of our DNA actually makes us unique. You may also be surprised to know that some of the DNA in strawberries is also ...
