halogen
Examples of halogen in the following topics:
-
Fluorescence Microscopy
- The fluorescent microscope uses a high-pressure mercury, halogen, or xenon vapor lamp that emits a shorter wavelength than that emitted by traditional brightfield microscopy.
-
Nonribosomal Peptide Antibiotics
- Nonribosomal peptides often have a cyclic and/or branched structures, can contain non-proteinogenic amino acids including D-amino acids, carry modifications like N-methyl and N-formyl groups, or are glycosylated, acylated, halogenated, or hydroxylated.
-
Chloroflexus and Relatives
- The Chloroflexi or Chlorobacteria are a phylum of bacteria containing isolates with a diversity of phenotypes including members that are aerobic thermophiles, which use oxygen and grow well in high temperatures, anoxygenic phototrophs, which use light for photosynthesis, and anaerobic halorespirers, which use halogenated organics (such as the toxic chlorinated ethenes and polychlorinated biphenyls) as energy sources.
