| unsaturated fat | <biochemistry> A fat that contains a carbon-carbon double bond, or a fat containing unsaturated fatty acids, such a fatty acid has double or triple covalent bonds and is thus able to add more atoms. Unsaturated fats are believed to lower blood cholesterol levels and are found at high levels in vegetable oils (olive oil, safflower oil, etc.) As a general rule, unsaturated fats are liquid at room temperature. (09 Oct 1997) |
|---|---|
| unsaturated fatty acid | <biochemistry> Fatty acid with one or more double bonds. (18 Nov 1997) |
| fats, unsaturated | Fats containing one or more double bonds, as from oleic acid, an unsaturated fatty acid. (12 Dec 1998) |
|---|---|
| fatty acids, unsaturated | Fatty acids containing one (monounsaturated) or multiple (polyunsaturated) double bonds. They predominate in most plant-derived fats. The number and position of each double bond can be specified, as in the systematic names, or the position of the double bond closest to the methyl group (omega) terminus can be specified to denote functional subdivisions of the overall group, e.g., omega-3 fatty acids. The numbers and positions of the double bonds have been linked to effects on plasma lipid, triglyceride, and cholesterol levels. (12 Dec 1998) |
| unsaturated | 1. Capable of absorbing or dissolving to a greater degree; as, an unsaturated solution. 2. <chemistry> Capable of taking up, or of uniting with, certain other elements or compounds, without the elimination of any side product; thus, aldehyde, ethylene, and ammonia are unsaturated.

| unsaturated alcohols | Those alcohol's whose carbon chains contain one or more double or triple bonds. (05 Mar 2000) |
| abdominal wall fat pad biopsy | <investigation, procedure, surgery> The removal of a small specimen of the abdominal wall fat pad for microscopic examination. Often used in the diagnosis of amyloidosis. Performed with a local anaesthetic. (25 Jun 1999) |
| Bichat's fat-pad | An encapsuled mass of fat in the cheek on the outer side of the buccinator muscle, especially marked in the infant; supposed to strengthen and support the cheek during the act of sucking. Synonym: corpus adiposum buccae, Bichat's fat-pad, Bichat's protuberance, fat body of cheek, sucking cushion, sucking pad, suctorial pad. (05 Mar 2000) |
| brown fat | A thermogenic type of adipose tissue containing a dark pigment, and arising during embryonic life in certain specific areas in many mammals, including man. It is prominent in the newborn of all species in which it occurs and remains a distinct and conspicuous tissue in the adults of certain species, especially those that hibernate. It is also called brown adipose tissue. (12 Dec 1998) |
| brown fat cell | <pathology> Brown fat is specialised for heat production and the adipocytes have many mitochondria in which an inner membrane protein can act as an uncoupler of oxidative phosphorylation allowing rapid thermogenesis. (18 Nov 1997) |
| buccal fat-pad | An encapsuled mass of fat in the cheek on the outer side of the buccinator muscle, especially marked in the infant; supposed to strengthen and support the cheek during the act of sucking. Synonym: corpus adiposum buccae, Bichat's fat-pad, Bichat's protuberance, fat body of cheek, sucking cushion, sucking pad, suctorial pad. (05 Mar 2000) |
| chicken fat clot | Clot formed in vitro or postmortem from leukocytes and plasma of sedimented blood. (05 Mar 2000) |
| combined fat-and carbohydrate-induced hyperlipaemia | Hyperlipoproteinaemia characterised by increased plasma levels of chylomicrons, VLDL, pre-beta-lipoproteins, and triglycerides, and slight rise of cholesterol on a normal diet, with beta-lipoproteins normal; may be accompanied by bouts of abdominal pain, hepatosplenomegaly, susceptibility to atherosclerosis, and abnormal glucose tolerance; probably autosomal recessive inheritance. Synonym: combined fat-and carbohydrate-induced hyperlipaemia, familial hyperchylomicronaemia with hyperprebetalipoproteinaemia, mixed hyperlipaemia. (05 Mar 2000) |
| white fat | <anatomy> Connective tissue that has been specialised to store fat. See: adipocyte. (25 Jun 1999) |
| multilocular fat | A thermogenic type of adipose tissue containing a dark pigment, and arising during embryonic life in certain specific areas in many mammals, including man. It is prominent in the newborn of all species in which it occurs and remains a distinct and conspicuous tissue in the adults of certain species, especially those that hibernate. It is also called brown adipose tissue. (12 Dec 1998) |
| wool fat | <physiology> A peculiar fatlike body, made up of cholesterin and certain fatty acids, found in feathers, hair, wool, and keratin tissues generally. Under the same name, it is prepared from wool for commercial purposes, and forms an admirable basis for ointments, being readily absorbed by the skin. Origin: L. Lana wool + oleum oil.

| mutton-fat keratic precipitates | Coalescent precipitate's forming small plaques that gradually become more translucent. (05 Mar 2000) |
