266Keshan disease Cardiomyopathy that is endemic in regions <strong>of</strong>China where there is severe selenium deficiency, <strong>and</strong> respondsto selenium supplementation, although other factors, includingcoxsackie virus <strong>and</strong> the mycotoxin moniliformin, may also beinvolved.See also kashin–beck syndrome.keshi yena Caribbean (Curaçao); hollowed out Dutch cheesefilled with meat, rice <strong>and</strong> currants.Kesp TM Texture vegetable protein made by a spinningprocess.ketchup (catsup or catchup) From the Chinese koechap orkitsiap, originally meaning brine <strong>of</strong> pickled fish. Now used forspicy sauce or condiment made with juice <strong>of</strong> fruit or vegetables,vinegar <strong>and</strong> spices.ketoacidosis (or ketonaemia) High concentrations <strong>of</strong> ketonebodies in the blood, so far in excess <strong>of</strong> the capacity for theirmetabolism that the blood level rises sufficiently to affect pH.May occur in patients with insulin-dependent diabetes mellitus,but rare in those with non-insulin-dependent diabetes.ketogenic amino acids See amino acids, ketogenic.ketogenic diet A diet poor in carbohydrate (20–30 g) <strong>and</strong> rich infat; causes accumulation <strong>of</strong> ketone bodies in tissue; formerlyused in the treatment <strong>of</strong> epilepsy. See also Atkins diet.ketonaemia See ketoacidosis.ketone bodies Acetone, acetoacetate <strong>and</strong> β-hydroxybutyric acid(not chemically a ketone) synthesised in liver from acetyl CoA(the product <strong>of</strong> β-oxidation <strong>of</strong> fatty acids), especially in thefasting state, <strong>and</strong> exported for use by other tissues as a metabolicfuel. When production exceeds the rate <strong>of</strong> utilisation the plasmaconcentration may rise high enough to cause significant ketoacidosis(especially in uncontrolled insulin-dependent diabetesmellitus), <strong>and</strong> significant amounts may be excreted in the urine(ketonuria).ketones Chemical compounds containing a carbonyl group(C=O), with two alkyl groups attached to the same carbon; thesimplest ketone is acetone (dimethylketone, (CH 3 ) 2 —C=O).ketonic rancidity Moulds <strong>of</strong> Penicillium <strong>and</strong> Aspergillus spp.attack fats containing short-chain fatty acids <strong>and</strong> produceketones with a characteristic odour <strong>and</strong> taste, so-called ketonicrancidity. Fats such as butter, coconut <strong>and</strong> palm kernel are mostsusceptible.Ketonil TM A protein-rich <strong>food</strong> low in phenylalanine for patientswith phenylketonuria.ketonuria Excretion <strong>of</strong> ketone bodies in the urine.ketosis High concentrations <strong>of</strong> ketone bodies in the blood.
