The botulinum neurotoxin type A light chain (BoNT/A LC) is a metalloprotease that enters motor neurons, cleaves its substrate SNAP-25, and disrupts neurotransmission, thereby resulting in flaccid paralysis. Utilizing a high-throughput-compatible FRET-based assay, large libraries of small molecules can be screened for their impact on BoNT/A LC enzymatic activity.

Electron Transport Chains

The final stage of cellular respiration is oxidative phosphorylation that consists of two steps: the electron transport chain and chemiosmosis. The electron transport chain is a set of proteins found in the inner mitochondrial membrane in eukaryotic cells. Its primary function is to establish a proton gradient that can be used during chemiosmosis to produce ATP and generate electron carriers, such as NAD+ and FAD, that are used in glycolysis and the citric acid cycle. The ETC is comprised of...

The Carbon Cycle

Carbon is the basis of all organic matter on Earth, and is recycled through the ecosystem in two primary processes: one in which carbon is exchanged among living organisms, and one in which carbon is cycled over long periods of time through fossilized organic remains, weathering of rocks, and volcanic activity. Human activities, including increased agricultural practices and the burning of fossil fuels, has greatly affected the balance of the natural carbon cycle. Biological Carbon Cycle All...

We propose a protocol to identify fatty acids without the need to purify them. It combines information on the retention times with the mass spectra of three types of fatty acid derivatives: fatty acid methyl esters (FAMEs), 4,4-dimethyl oxazoline derivatives (DMOX), and 3-pyridylcarbinyl esters (picolinyl).

Bromodeoxyuridine (BrdU) Labeling and Subsequent Fluorescence Activated Cell Sorting for Culture-independent Identification of Dissolved Organic Carbon-degrading Bacterioplankton

Environmental bacterioplankton are incubated with a model dissolved organic carbon (DOC) compound and a DNA labeling reagent, bromodeoxyuridine (BrdU). Afterward, DOC-degrading cells are separated from the bulk community based on their elevated BrdU incorporation using fluorescence activated cell sorting (FACS). These cells are then identified by subsequent molecular analyses.
FAQs
The parent chain provides the structural framework used to describe the molecule, so selecting a different continuous carbon sequence can change how branches and other features are represented. This choice directly affects systematic nomenclature and classification. Careful selection therefore prevents ambiguity and ensures that the name communicates the connectivity shown in the structural or skeletal formula.
Branches show that some carbon atoms connect to the main sequence rather than extending the same continuous path. Recognizing these points allows chemists to distinguish a branched structure from an unbranched one and to describe its arrangement accurately. That distinction is especially important when comparing compounds with similar compositions but different carbon connectivity and potentially different properties.
Rings interrupt the assumption that every carbon belongs to one open sequence, while multiple bonds add structural features that influence classification and nomenclature. During analysis, chemists must recognize these features rather than treating the formula as a simple single-bonded chain. Their presence can change how the structure is described and how its chemical behavior is interpreted.
Isomers can contain the same types and numbers of atoms while differing in how their carbon atoms are connected. Tracing the carbon framework reveals whether compounds have different branching, ring arrangements, or other connectivity patterns. This structural comparison allows chemists to distinguish substances that share a molecular composition but may differ in physical and chemical properties.
Begin by tracing the connected carbon sequences represented in the formula, then identify possible branching points, rings, and multiple bonds. Next, select the appropriate parent chain and use the recognized structural features to support classification and naming. Applying the same sequence consistently helps reduce missed connections and produces a clearer interpretation of the molecule.
The analysis supports systematic naming, reaction interpretation, compound synthesis, and identification of unknown substances. By clarifying how carbon atoms are connected, it gives chemists a common structural language for communicating results and relating molecular arrangement to physical or chemical properties. It is therefore useful before interpreting an organic molecule or predicting how its structure may affect its behavior.
