A nucleotide consisting of cytosine (a pyrimidine) and ribose. A nucleoside that is one of the four main riboside components of ribonucleic acid. It consists of a cytosine and D-ribose.  

A high level of cystathionine in the urine caused by a mutation in the gene for cystathionase which catalyzes the production of cysteine from cystathionine. A hereditary disease caused by a deficiency of the enzyme important in metabolizing cystathionine, resulting in mental retardation, thrombocytopenia, and acidosis.  

Fatty acids occurring in the oils or fat of every plant of the order Malvales, except for cocoa butter from Theobroma cocoa. From a food toxicological point of view, only the acids in the oils of cottonseed and kapok seed are of significance. The most important acids are sterculic and malvalic acids; both are toxic…

A drug that is used as a muscle relaxant.  

Glycosides from which cyanide is formed by the activity of hydrolytic enzymes. More than 1000 plant species from 90 families and 250 genera have been reported to be cyanophoric. The cyanogenic glycoside molecule consists of a monosaccharide (glucose) or disaccharide (vicianose or gentiobiose) and an aglycone in the form of a β-hydroxynitrile. The glycoside is…

A nucleotide consisting of cytosine (a pyrimidine), ribose, and three high- energy phosphate groups.  

Nonexperimental studies in which data on exposure as well as biological effects are collected at the same time. This kind of study is often used to describe the prevalence of certain exposures or diseases in a population. From an etiological point of view, an essential disadvantage of these studies is the problem of discerning effect…

The organ in which the critical concentration is reached first under specified conditions for a given population.  

The target cell/organ concentration at which adverse (reversible/irreversible) functional changes occur. These changes are called critical effects.  

The invaginations of the inner mitochondrial membrane.
