Carnitine is a quaternary ammonium compound involved in metabolism in most mammals, plants, and some bacteria. In support of energy metabolism, carnitine transports long-chain fatty acids from the cytosol into mitochondria to be oxidized for free energy production, and also participates in removing products of metabolism from cells. Given its key metabolic roles, carnitine is concentrated in tissues like skeletal and cardiac muscle that metabolize fatty acids as an energy source. Generally individuals, including strict vegetarians, synthesize enough L-carnitine in vivo.

Calcein, also known as fluorexon, fluorescein complex, is a fluorescent dye with excitation and emission wavelengths of 495 and 515 nm, respectively, and has the appearance of orange crystals. Calcein self-quenches at concentrations above 70 mM and is commonly used as an indicator of lipid vesicle leakage. It has also been traditionally used as a complexometric indicator for titration of calcium ions with EDTA, and for fluorometric determination of calcium.

Ibrexafungerp, sold under the brand name Brexafemme, is an antifungal medication used to treat vulvovaginal candidiasis (VVC) (vaginal yeast infection). It is taken orally (by mouth). It is also currently undergoing clinical trials for other indications via an intravenous (IV) formulation. An estimated 75% of women will have at least one episode of VVC and 40 to 45% will have two or more episodes in their lifetime.

Diphthamide is a post-translationally modified histidine amino acid found in archaeal and eukaryotic elongation factor 2 (eEF-2).

'Ethylenediamine-N,N'-disuccinic acid (EDDS') is an aminopolycarboxylic acid. It is a colourless solid that is used as chelating agent that may offer a biodegradable alternative to EDTA, which is currently used on a large scale in numerous applications.

Monatin, commonly known as arruva, is a naturally occurring, high intensity sweetener isolated from the plant Sclerochiton ilicifolius, found in the Transvaal region of South Africa. Monatin contains no carbohydrate or sugar, and nearly no food energy, unlike sucrose or other nutritive sweeteners.

Gabaculine is a naturally occurring neurotoxin first isolated from the bacteria Streptomyces toyacaensis, which acts as a potent and irreversible GABA transaminase inhibitor, and also a GABA reuptake inhibitor. Gabaculine is also known as 3-amino-2,3-dihydrobenzoic acid hydrochloride and 5-amino cyclohexa-1,3 dienyl carboxylic acid. Gabaculine increased GABA levels in the brain and had an effect on convulsivity in mice.

Yersiniabactin (Ybt) is a siderophore found in the pathogenic bacteria Yersinia pestis, Yersinia pseudotuberculosis, and Yersinia enterocolitica, as well as several strains of enterobacteria including enteropathogenic Escherichia coli and Salmonella enterica. Siderophores, compounds of low molecular mass with high affinities for ferric iron, are important virulence factors in pathogenic bacteria. Iron—an essential element for life used for such cellular processes as respiration and DNA replication—is extensively chelated by host proteins like lactoferrin and ferritin; thus, the pathogen produc

Aminocyclopyrachlor (AMCP) is a selective, low-toxicity, auxin-mimicking herbicide that provides pre- and post-emergent control of broadleaf weeds on several non-food use sites including rights of way, wildlife management areas, recreational areas, turf/lawns, golf courses and sod farms. It was conditionally registered as Imprelis by DuPont in August 2010, and first used in Fall 2010, though used experimentally since 2008 or before.

Gabapentinoids, also known as α2δ ligands, are a class of drugs that are chemically derivatives of the inhibitory neurotransmitter gamma-aminobutyric acid (GABA) (i.e., GABA analogues) which bind selectively to the α2δ protein that was first described as an auxiliary subunit of voltage-gated calcium channels (VGCCs).

thumb|The sequence ATGG has two 3-mers: ATG and TGG. In bioinformatics, '''k-mers' are substrings of length k contained within a biological sequence. Primarily used within the context of computational genomics and sequence analysis, in which k-mers are composed of nucleotides (i.e. A, T, G, and C), k-mers are capitalized upon to assemble DNA sequences, improve heterologous gene expression, identify species in metagenomic samples, and create attenuated vaccines. Usually, the term k''-mer refers to all of a sequence's subsequences of length k, such that the sequence AGAT would have four monomers

3-Dehydrocarnitine is an aliphatic quaternary ammonium betaine that is part of the carnitine family. At physiological pH of 7.3, the major species of 3-dehydrocarnitine is its zwitterionic form, the conjugate base of 3-dehydrocarnitinium. 3-Dehydrocarnitine is classified as a short-chain keto acid, as it has a carbon chain containing less than six carbon atoms. It is an intermediate in carnitine degradation and is formed from D- or L-carnitine. The enzymes responsible for the degradation of carnitine to 3-dehydrocarnitine are carnitine-3-dehydrogenase or (S)-carnitine-3-dehydrogenase.

Target peptide sequence

Nullomers are short sequences of DNA that do not occur in the genome of a species (for example, humans), even though they are theoretically possible. Nullomers must be under selective pressure - for example, they may be toxic to the cell. Some nullomers have been shown to be useful to treat leukemia, breast, and prostate cancer. They are not useful in healthy cells because normal cells adapt and become immune to them. Nullomers are also being developed for use as DNA tags to prevent cross contamination when analyzing crime scene material.

chemical compound

Aminophosphonates are organophosphorus compounds with the formula (RO)2P(O)CH2NR2. These compounds are structural analogues of amino acids in which a carboxylic moiety is replaced by phosphonic acid or related groups. Acting as antagonists of amino acids, they inhibit enzymes involved in amino acid metabolism and thus affect the physiological activity of the cell. These effects may be exerted as antibacterial, plant growth regulatory or neuromodulatory. They can act as ligands, and heavy metal complexes with aminophosphonates have medical applications.
