Alpha-ethltryptamine: An illicit hallucinogenic drug related to tryptamine. Street names for alpha-ethyltryptamine include: Alpha-ET; ET; Love pearls; Trip (also refers to LSD).
Many agents in the class of tryptamines are hallucinogenic substances that exist naturally in some plants, fungi, and animals, but also can be produced synthetically. These hallucinogens have been placed in Schedule I of the CSA (Controlled Substances Act) and include psilocybin, psilocyn, bufotenine, alpha-ethyltryptamine, diethyltryptamine, and dimethyltryptamine. There are also numerous types of tryptamines available, including AMT (alpha-methyltryptamine) and Foxy (5-MeO-DIPT), that are not listed under the CSA.
- Alpha-fetoprotein (AFP)
Alpha-fetoprotein (AFP): AFP is a plasma protein that is normally produced by the fetus. It serves as the basis for some valuable tests. AFP is manufactured principally in the fetus’s liver and gastrointestinal (GI) tract besides the yolk sac, a structure temporarily present during embryonic development. The AFP level is typically high in the fetus’s […]
- Alpha-glucosidase inhibitor
Alpha-glucosidase inhibitor: A class of oral medications for type 2 diabetes that decrease the absorption of carbohydrates from the intestine, resulting in a slower and lower rise in blood glucose throughout the day, especially right after meals. Before carbohydrates are absorbed from food, they must be broken down into smaller sugar particles like glucose by […]
- Alpha-linolenic acid
Alpha-linolenic acid: An essential fatty acid found in flaxseed oil, canola oil and walnuts. Abbreviated ALA.
Alpha-synuclein: One in a family of structurally related proteins that are prominently expressed in the central nervous system. Aggregated alpha-synuclein proteins form brain lesions that are hallmarks of some neurodegenerative diseases (synucleinopathies). The gene for alpha-synuclein, which is called SNCA, is on chromosome 4q21. Defects in this protein are believed to be related to the […]
- Alport syndrome
Alport syndrome: A hereditary condition characterized by kidney disease, deafness, and sometimes eye defects. Alport syndrome involves inflammation of the kidney (nephritis), often progressing to kidney failure, and sensory nerve hearing loss. Progression to kidney failure is gradual and usually occurs in males before 50 years of age.
