24.3: Lipid Metabolism - Medicine LibreTexts
网页2022年5月13日 · Lipid metabolism entails the oxidation of fatty acids to either generate energy or synthesize new lipids from smaller constituent molecules. Lipid metabolism is associated with carbohydrate metabolism, as products of glucose (such as acetyl CoA) can be converted into lipids. Figure 24.3.1 24.3. 1: Triglyceride Broken Down into a …

4.4: The Functions of Carbohydrates in the Body
网页2020年8月14日 · Lipid Metabolism. As blood-glucose levels rise, the use of lipids as an energy source is inhibited. Thus, glucose additionally has a “fat-sparing” effect. This is because an increase in blood glucose stimulates release of the hormone insulin, which tells cells to use glucose (instead of lipids) to make energy.
5.4: Digestion and Absorption of Lipids - Medicine LibreTexts
网页Figure 5.4.1 5.4. 1: Lipid Digestion. In the stomach, gastric lipase starts to break down triacylglycerols into diglycerides and fatty acids. Within two to four hours after eating a meal, roughly 30 percent of the triacylglycerols are converted to diglycerides and fatty acids.
6.3: Vitamins Important for Metabolism - Medicine LibreTexts
网页2020年8月14日 · Thiamine (B 1) Thiamine, one of the water-soluble vitamins, is especially important in glucose metabolism. It acts as a cofactor for enzymes that break down glucose for energy production (Figure 6.3.1 6.3. 1). Additionally, thiamine plays a role in the synthesis of ribose from glucose and is therefore required for RNA, DNA, and ATP …
3.1: Fed and fasted states - Medicine LibreTexts
网页Under these conditions, most tissues (liver, skeletal muscle, adipose, brain, and red blood cells) will increase glucose uptake and oxidation (table 3.1 and figure 3.1). Each tissue will take up glucose in the fed state using one of the glucose transporters (GLUT) known to facilitate glucose transport across the plasma membrane.
6.2: Lipid transport - Medicine LibreTexts
网页2021年10月25日 · As such, a transport system for distribution of major lipids is in place to aid in the movement of these compounds. This system involves the family of lipoproteins, which have distinct roles in carrying dietary lipids, lipids synthesized through de novo mechanism in the liver, and for reverse cholesterol transport (figure 6.6).
4.4: Digestion and Absorption of Lipids - Medicine LibreTexts
网页2020年8月14日 · Lipolysis is the process by which the triacylglyceride is removed from the lipid droplet with the fat cells, broken into 3 fatty acids and glycerol. The glycerol is secreted from the cells along with some but not all of the fatty acids. These are transported to the liver where the glycerol may be converted to glucose.

网页2020年8月14日 · Summarize the roles of minerals important in blood function and renewal. In a well-balanced diet, minerals are plentiful, and herbs are power-packed with minerals. Eat more plants, spice up your food, and drink herbal teas to obtain optimum mineral nutrition. Figure 6.4.1 6.4. 1: Several different minerals.
