The Regulation of Retinoic Acid Formation
Nutrition Reviews, 2009Rat liver microsomal as well as cytosolic retinol dehydrogenases from cellular retinal-binding protein (CRBP)-retinal from CRBP-retinol. A cytosolic dehydrogenase transforms retinal into retinoic acid. Apo-CRBP and ethanol inhibit the cytosolic but not the microsomal retinol dehydrogenase, the latter being the primary enzyme in the rate-limiting step ...

Regulation of the proteome by amino acids
PROTEOMICS, 2016Besides their main contribution as substrates for protein synthesis, amino acids as signaling molecules could exert some regulatory functions on protein synthesis and/or proteolysis that have been emphasized in a number of recent studies. Several publications have highlighted supplemental roles of those amino acids in protein metabolism as well as in ...

Regulation and metabolism of arachidonic acid
Clinical Reviews in Allergy & Immunology, 1999The metabolism of AA reflects a carefully balanced series of biochemical pathways. The level of free arachidonate in a cells is controlled by de novo synthesis, dietary uptake, and transcellular metabolism. Lysophospholipids are key controlling substrates for a variety of acyl transferase and transacylase reactions, whose combined effect is to remodel ...

Regulation of bile acid synthesis
Frontiers in Bioscience, 1998Bile acids are important physiological agents required for disposal of cholesterol and absorption of vitamins and fats. Bile acids are synthesized from cholesterol in the liver. Enterohepatic circulation of bile acids is very efficient and plays an important physiological role in lipid absorption and secretion, and regulation of bile acid biosynthesis ...

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.

Peptides As Regulators Of Gastric Acid Secretion
Annual Review of Physiology, 1988Several peptides are important regulators of gastric acid secretion. The best characterized is gastrin. This circulating hormone is produced in the gastric antrum and mediates the gastric phase of acid secretion. Somatostatin is important as an inhibitory regulator of acid secretion, but the relative importance of paracrine versus endocrine delivery to

Regulation of Bile Acid Synthesis
1974Bile acids formed from cholesterol in the liver are defined as “primary” bile acids. In man, these are chenodeoxycholic acid and cholic acid. Following conjugation with glycine or taurine the bile acids are secreted into the bile and stored in the gallbladder.
