Lactones
|
D007783 |

Lactoperoxidase
|
D007784 |

|
Lactose
|
D007785 |
[A disaccharide of GLUCOSE and GALACTOSE in human and cow milk. It is used in pharmacy for tablets, in medicine as a nutrient, and in industry.

Lactose Factors
|
D007786 |
[Plasmids which determine the ability of a bacterium to ferment lactose.
] |
|
Lactose Intolerance
|
D007787 |
[The condition resulting from the absence or deficiency of LACTASE in the MUCOSA cells of the GASTROINTESTINAL TRACT, and the inability to break down LACTOSE in milk for ABSORPTION. Bacterial fermentation of the unabsorbed lactose leads to symptoms that range from a mild indigestion (DYSPEPSIA) to severe DIARRHEA. Lactose intolerance may be an inborn error or acquired.

|
Lactose Synthase
|
D007788 |
[An enzyme complex that catalyzes the transfer of GALACTOSE from UDP GALACTOSE to GLUCOSE, forming LACTOSE. The enzyme complex is composed of a B subunit, ALPHA-LACTALBUMIN, which changes the substrate specificity of the A subunit, N-ACETYLLACTOSAMINE SYNTHASE, from N-ACETYLGLUCOSAMINE to glucose making lactose synthesis the preferred reaction.

Lactose Tolerance Test
|
D007789 |
[A measure of a patient's ability to break down lactose.
] |
|
Lactosylceramides
|
D007790 |
[Glycosphingolipids which contain as their polar head group a lactose moiety bound in glycosidic linkage to the hydroxyl group of ceramide. Their accumulation in tissue, due to a defect in lactosylceramide beta-galactosidase, is the cause of lactosylceramidosis.

Lactotrophs
|
D052682 |
[Anterior pituitary cells that produce PROLACTIN.

|
Lactoylglutathione Lyase
|
D007791 |
[An enzyme that catalyzes the interconversion of methylglyoxal and lactate, with glutathione serving as a coenzyme. EC 4.4.1.5.

|
Lactulose
|
D007792 |
[A synthetic disaccharide used in the treatment of constipation and hepatic encephalopathy. It has also been used in the diagnosis of gastrointestinal disorders. (From Martindale, The Extra Pharmacopoeia, 30th ed, p887)

Lafora Disease
|
D020192 |
[A form of stimulus sensitive MYOCLONIC EPILEPSY inherited as an autosomal recessive condition. The most common presenting feature is a single seizure in the second decade of life. This is followed by progressive myoclonus, myoclonic seizures, tonic-clonic seizures, focal occipital seizures, intellectual decline, and severe motor and coordination impairments. Most affected individuals do not live past the age of 25 years. Concentric amyloid (Lafora) bodies are found in neurons, liver, skin, bone, and muscle (From Menkes, Textbook of Childhood Neurology, 5th ed, pp111-110).

Lagenidium
|
D044726 |
[A genus of OOMYCETES in the family Lagenidiaceae. One species (L. giganteum) parasitizes the larval stage of MOSQUITOES and is used in its biological control (PEST CONTROL, BIOLOGICAL); it also causes disease in freshwater FISHES.

|
Lagerstroemia
|
D031563 |
[A plant genus of the family LYTHRACEAE. Members contain lagertannin and have hypoglycemic effects.
] |
|
Lagomorpha
|
D007793 |
[Single genus in the family Ochotonidae.
, Family of small short-haired mammals without tails and shrill voice.
, An order of small mammals comprising two families, Ochotonidae (pikas) and Leporidae (RABBITS and HARES). Head and body length ranges from about 125 mm to 750 mm. Hares and rabbits have a short tail, and the pikas lack a tail. Rabbits are born furless and with both eyes and ears closed. HARES are born fully haired with eyes and ears open. All are vegetarians. (From Nowak, Walker's Mammals of the World, 5th ed, p539-41)

Lagovirus
|
D029321 |
[A genus of the family CALICIVIRIDAE, associated with infections in rabbits and hares, responsible for epidemics with high mortality. RABBIT HEMORRHAGIC DISEASE VIRUS is the type species.

Lakes
|
D060106 |
[Inland bodies of still or slowly moving FRESH WATER or salt water, larger than a pond, and supplied by RIVERS and streams.

Lambdapapillomavirus
|
D052691 |
[A genus of DNA viruses in the family papillomaviridae, causing mucosal and cutaneous lesions in cats and dogs. Canine oral papillomavirus is the type species.

|
Lambert-Eaton Myasthenic Syndrome
|
D015624 |
[An autoimmune disease characterized by weakness and fatigability of proximal muscles, particularly of the pelvic girdle, lower extremities, trunk, and shoulder girdle. There is relative sparing of extraocular and bulbar muscles. CARCINOMA, SMALL CELL of the lung is a frequently associated condition, although other malignancies and autoimmune diseases may be associated. Muscular weakness results from impaired impulse transmission at the NEUROMUSCULAR JUNCTION. Presynaptic calcium channel dysfunction leads to a reduced amount of acetylcholine being released in response to stimulation of the nerve. (From Adams et al., Principles of Neurology, 6th ed, pp 1471)
