Regulation of bile acid synthesis
Hepatology, 1991HEPATIC CHOLESTEROL HOMEOSTASIS The liver plays a central role in the regulation of cholesterol homeostasis. Under normal conditions, cholesterol input into the body equals output; cholesterol homeostasis is maintained. Under pathologic conditions, enhancement of cholesterol input into the liver or a reduction in hepatic cholesterol output may ...

REGULATION OF FATTY ACID SYNTHESIS
Annual Review of Plant Physiology and Plant Molecular Biology, 1997▪ Abstract All plant cells produce fatty acids from acetyl-CoA by a common pathway localized in plastids. Although the biochemistry of this pathway is now well understood, much less is known about how plants control the very different amounts and types of lipids produced in different tissues.

Abstract The concentration of H+ ([H+]) in various compartments of the body is critical to homeostasis. Because the respiratory system has a key role in H+ regulation through CO2 excretion by the lungs, we need to understand acid-base regulation. In addition to the lungs, the kidneys are also important in H+ regulation.

Acid-base regulation in pregnancy
American Journal of Physiology-Legacy Content, 1976Plasma bicarbonate decreases during normal pregnancy. To assess what roles increased extra cellular volume or alterations in parathyroid hormone levels (iPTH) have in the maintenance of this decrement, we evaluated acid-base metabolism in eleven 3rd-trimester women. Base-line pH and PCO2 were 7.44 and 27.3 mmHg, respectively. Mean tubular reabsorption

Regulation of Gastric Acid Secretion
Annual Review of Physiology, 1979The three stimulants of gastric acid secretion likely to have physiological roles in regulation of secretion are acetylcholine, gastrin, and histamine. Acetylcholine is released by vagal and intramucosal reflex stimulation, acting directly on the parietal cell.

REGULATION OF BILE ACID BIOSYNTHESIS
Gastroenterology Clinics of North America, 1999This article provides a review of the pathways through which cholesterol is degraded to bile acids. Regulation of key enzymes in the bile acid biosynthestic pathways is discussed. The important role of these pathways in the maintenance of cholesterol homeostasis and the possible therapeutic implications for the treatment of hypercholesterolemia are ...

Regulation of the acid-base status is an imperative task for maintenance of homeostasis in living animals. Deviations of pH from the predetermined setpoint values may result in reduced metabolic performance as a result of the often pronounced optima in the overall pH/activity relationships of metabolic pathways.

Regulation of fatty acid transport
Current Opinion in Lipidology, 2004The aim of the present review is to summarize recent developments in the area of regulation of fatty acid transport.While controversy still exists regarding the contribution of passive diffusion versus protein-mediated fatty acid transport, both processes are now widely accepted.

Abstract Maintaining a normal pH (7.35–7.45) is necessary for normal physiologic function. Beyond a normal range, widespread organ dysfunction ensues. Normal acid-base physiology is critical for numerous physiologic functions, including enzyme activity, chemical reactions, and transport of oxygen throughout the body.

[Fatty acids regulate NOX activity].
Annales de biologie clinique, 2006NADPH oxidase (NOX) is a multimeric enzyme including a catalytic unit, gp91(phox), and several regulating subunits: p22(phox), p40(phox), p47(phox), p67(phox). This enzyme, also known as flavocytochrome b(588), is responsible for a deliberate production of superoxyde anion (O2*-).
