A colorless liquid used as a solvent and an antiseptic. It is one of the ketone bodies produced during ketoacidosis.
Compounds in which a methyl group is attached to the cyano moiety.
Derivatives of the simplest aromatic ketone acetophenone (of general formula C6H5C(O)CH3).
An alkylating agent that forms DNA ADDUCTS at the C-8 position in GUANINE, resulting in single strand breaks. It has demonstrated carcinogenic action.
An iodinated radiographic contrast medium used as acetrizoate sodium in HYSTEROSALPINGOGRAPHY.
Acetyl CoA participates in the biosynthesis of fatty acids and sterols, in the oxidation of fatty acids and in the metabolism of many amino acids. It also acts as a biological acetylating agent.
An enzyme that catalyzes the formation of acetoacetyl-CoA from two molecules of ACETYL COA. Some enzymes called thiolase or thiolase-I have referred to this activity or to the activity of ACETYL-COA C-ACYLTRANSFERASE.
Enzyme that catalyzes the final step of fatty acid oxidation in which ACETYL COA is released and the CoA ester of a fatty acid two carbons shorter is formed.
A carboxylating enzyme that catalyzes the conversion of ATP, acetyl-CoA, and HCO3- to ADP, orthophosphate, and malonyl-CoA. It is a biotinyl-protein that also catalyzes transcarboxylation. The plant enzyme also carboxylates propanoyl-CoA and butanoyl-CoA (From Enzyme Nomenclature, 1992) EC 6.4.1.2.
An enzyme that catalyzes reversibly the hydrolysis of acetyl-CoA to yield CoA and acetate. The enzyme is involved in the oxidation of fatty acids. EC 3.1.2.1.
Formation of an acetyl derivative. (Stedman, 25th ed)
An acetic acid ester of CARNITINE that facilitates movement of ACETYL COA into the matrices of mammalian MITOCHONDRIA during the oxidation of FATTY ACIDS.
A neurotransmitter found at neuromuscular junctions, autonomic ganglia, parasympathetic effector junctions, a subset of sympathetic effector junctions, and at many sites in the central nervous system.
Compounds that block release of the neurotransmitter ACETYLCHOLINE.
An enzyme that catalyzes the hydrolysis of ACETYLCHOLINE to CHOLINE and acetate. In the CNS, this enzyme plays a role in the function of peripheral neuromuscular junctions. EC 3.1.1.7.
The N-acetyl derivative of CYSTEINE. It is used as a mucolytic agent to reduce the viscosity of mucous secretions. It has also been shown to have antiviral effects in patients with HIV due to inhibition of viral stimulation by reactive oxygen intermediates.
Cardioactive derivatives of lanatoside A or of DIGITOXIN. They are used for fast digitalization in congestive heart failure.
Alpha- or beta-acetyl derivatives of DIGOXIN or lanatoside C from Digitalis lanata. They are better absorbed and longer acting than digoxin and are used in congestive heart failure.
The simplest two carbon alkyne with the formula HCCH.
An enzyme that catalyzes the conversion of acetate esters and water to alcohols and acetate. EC 3.1.1.6.
The N-acetyl derivative of galactosamine.
The N-acetyl derivative of glucosamine.
A beta-N-Acetylhexosaminidase that catalyzes the hydrolysis of terminal, non-reducing 2-acetamido-2-deoxy-beta-glucose residues in chitobiose and higher analogs as well as in glycoproteins. Has been used widely in structural studies on bacterial cell walls and in the study of diseases such as MUCOLIPIDOSIS and various inflammatory disorders of muscle and connective tissue.
Peptidoglycan immunoadjuvant originally isolated from bacterial cell wall fragments; also acts as pyrogen and may cause arthritis; stimulates both humoral and cellular immunity.
An enzyme that catalyzes the transfer of a methyl group from S-adenosylmethionine to N-acetylserotonin to form N-acetyl-5-methoxytryptamine (MELATONIN).
An agent used as a substrate in assays for cholinesterases, especially to discriminate among enzyme types.
Enzymes catalyzing the transfer of an acetyl group, usually from acetyl coenzyme A, to another compound. EC 2.3.1.
A genomic region found in DROSOPHILA. The region contains genes encoding BASIC HELIX-LOOP-HELIX PROTEINS that play a critical role in the regulation of pattern formation during EMBRYONIC DEVELOPMENT.
Success in bringing an effort to the desired end; the degree or level of success attained in some specified area (esp. scholastic) or in general.
A plant genus of the family ASTERACEAE that has long been used in folk medicine for treating wounds.
Tendon that connects the muscles in the back of the calf to the HEEL BONE.
A lack of HYDROCHLORIC ACID in GASTRIC JUICE despite stimulation of gastric secretion.
A genus of OOMYCETES in the family Saprolegniaceae. They are pathogens of FISHES and INSECTS.
A genus of gram-negative organisms including saprophytic and parasitic or pathogenic species.
An organism originally isolated from sewage, manure, humus, and soil, but recently found as a parasite in mammals and birds.
Gram-negative organisms including apparently free-living saphrophytes as well as mammalian and avian parasites, and possibly pathogens.
An autosomal dominant disorder that is the most frequent form of short-limb dwarfism. Affected individuals exhibit short stature caused by rhizomelic shortening of the limbs, characteristic facies with frontal bossing and mid-face hypoplasia, exaggerated lumbar lordosis, limitation of elbow extension, GENU VARUM, and trident hand. (Online Mendelian Inheritance in Man, http://www.ncbi.nlm.nih.gov/Omim, MIM#100800, April 20, 2001)
A genus of gram-negative, strictly aerobic, non-spore forming rods. Soil and water are regarded as the natural habitat. They are sometimes isolated from a hospital environment and humans.
A species of gram negative, aerobic, denitrifying bacteria in the genus ACHROMOBACTER.
The type species of gram negative, aerobic bacteria in the genus ACHROMOBACTER. Previously in the genus ALCALIGENES, the classification and nomenclature of this species has been frequently emended. The two subspecies, Achromobacter xylosoxidans subsp. denitrificans and Achromobacter xylosoxidans subsp. xylosoxidans are associated with infections.
