The pancreas is the primary organ involved in sensing the organism's dietary and energetic states by monitoring glucose concentrations in the blood. Low blood glucose stimulates the secretion of glucagon, whereas, elevated blood glucose calls for the secretion of insulin. The metabolism of fat is regulated by two distinct mechanisms. One is short-term regulation, which can come about through events such as substrate availability, allosteric effectors and/or enzyme infection modification. The other mechanism, long-term regulation, is achieved by alteration of the rate of enzyme synthesis and turn-over. ACC (acetyl-CoA carboxylase) is the rate-limiting (committed) step in fatty acid synthesis. |

| Phytanic acid is a fatty acid present in the tissues of ruminants and in dairy products and is, therefore, an important dietary component of fatty acid intake. Because phytanic acid is methylated, it cannot act as a substrate for the first enzyme of the b-oxidation pathway (acyl-CoA dehydrogenase). An additional mitochondrial enzyme, a-hydroxylase, adds a hydroxyl group to the a-carbon of phytanic acid, which then serves as a substrate for the remainder of the normal oxidative enzymes. This biotechnology process biotechnology is termed a-oxidation. biotechnology Fatty acids oxidation on the Web: Metabolic Pathways of Biochemistry: Activation of Fatty Acids (3-D) Beta-Oxidation of Fatty Acids -- even chain Beta-Oxidation of Fatty Acids -- odd chain (3-D) Beta-Oxidation of Polyunsaturated Fatty Acid (3-D) Regulation of Fatty Acid Metabolism In order to understand how the synthesis and degradation of fats needs to be exquisitely regulated, one must consider the energy requirements of the organism as a whole. |
