The sucrose molecule has many oxygen-hydrogen (O–H) bonds which are polar. The charge-density model shows the positive areas near the hydrogen atom as blue and the negative area near the oxygen atom ...

Later it was found that the sugar in nucleic ... was to make physical models to narrow down the possibilities and eventually create an accurate picture of the molecule. The King's team took ...

In plants, the space between cells is a key battleground during infection. To avoid recognition in this space, a strain of ...

Several scientists put forth suggestions for how this might occur, but it was Levene's "polynucleotide" model that proved ... nitrogen-containing bases, a sugar molecule, and a phosphate group.

(It takes two bases to form a rung -- one for each side of the ladder.) A sugar molecule, a base, and a phosphate molecule group together to make up a nucleotide. Nucleotides are abundant in the ...

This backbone is composed of alternating sugar and phosphate groups, and defines directionality of the molecule. DNA and RNA are composed of nucleotides that are linked to one another in a chain ...

In plants, the space between cells is a key battleground during infection. To avoid recognition in this space, a strain of the bacterial tomato disease Pseudomonas syringae manipulates plants by ...

A new study led by the University of Oxford has revealed that glycosyrin does this by mimicking galactose, a simple sugar found in ... the structure of this molecule, its biosynthesis, and its ...
