Aerobic metabolism
Metabolic reactions that require oxygen. Processing of nutrients in the presence of oxygen; a metabolic pathway that uses oxygen to convert glucose into cellular energy.

Advanced cardiac life support
Advanced resuscitation techniques including airway management, arrhythmia detection, drug therapy, and defibrillation. The resuscitation of dying patients; a process that involves management of the airway, reestablishment of breathing, and the restoration of spontaneous heart rhythm, blood pressure, and organ perfusion. ACLS begins with the recognition of cardiac or respiratory emergencies, and includes basic life support…

Adsorb
To attract and retain substances on the surface. For example, dietary fiber can adsorb cholesterol and facilitate its excretion via the feces. Attachment of a substance to the surface of another material.

Adrenocorticotropin hormone
Hormone released by the anterior pituitary that stimulates the release of the adrenal cortical steroid hormones (cortisol, corticosteroid, hydrocortisone, dehydroepiandrosterone, and aldosterone). Its release, in turn, is stimulated by the corticotropin-releasing hormone (CRH) that is released by the hypothalamus.

Adrenalcortical hormones
Steroid hormones produced by the adrenal cortex.

Adipsin
Also known as complement factor D. It is a protein that is a member of the trypsin family of peptidases. It is a component of the alternative complement pathway best known for its role in the humoral suppression of inflammation by infectious agents. The protein is also a serine protease that is secreted by adipocytes…

Adenyl cyclase
The enzyme responsible for the conversion of ATP to cyclic AMP, an important second messenger for hormones that stimulate catabolic processes. An enzyme that catalyzes the production of cyclic AMP (adenosine 3′,5′-cyclic monophosphate) from ATP (adenosine triphosphate). It is present on most cell surfaces.

Ad libitum
A Latin term meaning to eat freely or to have unrestricted access to food.
-
Acylcarnitine transport system
Essential for the oxidation of fatty acids in the mitochondria. The fatty acids are activated by conversion to their CoA thioesters. This activation requires ATP and the enzyme, acyl CoA synthase or thiokinase. There are several thiokinases, which differ with respect to their specificity for the different fatty acids. The activation step is dependent on…

Acylation
The addition of an acyl group (carbon chain) to a substrate. Incorporation of an acyl (alkanoyl) group into a chemical compound.
