Hydrocarbons that have a carbon-oxygen (CO) pair as part of their chemical structure The oxygen is attached to the carbon by a double bond that makes ketones less stable and more reactive than an alcohols
by-products produced as a result of fat metabolism which occurs during periods of hyperglycemia or inadequate carbohydrate intake kinetics: 1 the study of reaction rates 2 The study of the relationship between force and mass L
Chemicals that the body makes when there is not enough insulin in the blood and it must break down fat for its energy Ketone bodies can poison and even kill body cells When the body does not have the help of insulin, the ketones build up in the blood and then "spill" over into the urine so that the body can get rid of them The body can also rid itself of one type of ketone, called acetone, through the lungs This gives the breath a fruity odor Ketones that build up in the body for a long time lead to serious illness and coma See also: Diabetic ketoacidosis
A homologous series of organic molecules whose functional group is an oxygen atom joined to a carbon atom—by a double bond—in a carbon-hydrogen based molecule
An organic compound that contains the bi-valent ketone groups Usually a colorless volatile liquid, such as acetone or dimethyl ketone, but may also be a crystalline solid, such as camphor
a chemical produced when there is a shortage of insulin in the blood and the body breaks down body fat for energy High levels of ketones can lead to diabetic ketoacidosis and coma Sometimes referred to as ketone bodies
A homologous series of organic molecules whose functional group is an oxygen atom joined to a carbon atom-by a double bond-in a carbon-hydrogen based molecule
Waste product produced when the body is using fat as an energy source Ketones are acids, and can cause damage or death to cells Excess ketones accumulate in the blood and are excreted in the urine Acetone is a ketone which can be eliminated through the lungs Ketoacidotic animals often have a chemical smell to their breath (Some nail polish removers contain acetone - it is a similar smell)
Any of a class of organic compounds containing a carbonyl group (CO; see functional group) bonded to two carbon atoms. Ketones can participate in many chemical reactions, though to a lesser extent than the related aldehydes. Many more complex organic compounds have ketones as building blocks. Their chief industrial use is as solvents and in the manufacture of explosives, lacquers, paints, and textiles. Acetone is the most important ketone; several sugars and some natural and synthetic steroids are ketones. In ketosis, ketones produced by lipid metabolism accumulate in the blood and urine in abnormal amounts, usually because of starvation or a metabolic disease such as diabetes mellitus
A carbon atom double-bonded to an oxygen and single-bonded to two chemical groups (such as methane, benzene, anything besides hydrogen) The carbon-oxygen double bond part is known as a carbonyl group (-C=O) An example is acetone,which is a carbonyl group attached to two methanes (methyl groups: -CH3)
One of a large class of organic substances resembling the aldehydes, obtained by the distillation of certain salts of organic acids and consisting of carbonyl (CO) united with two hydrocarbon radicals
