Chemists found a way to identify a complex sugar molecule in the cell walls of Mycobacterium tuberculosis, the world's deadliest pathogen. This labeling could lead to simpler, faster TB tests.

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 ...

(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 ...

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 ...
