The primary role of carbohydrates is to supply energy to all cells in the body. Carbohydrates Proteins Lipids Nucleic Acids Scroll down and read about “Good and bad ... How are carbohydrates, protein, and fat stored in our bodies? Information on the anatomy of the liver can be found here. The first step in lipid metabolism is the hydrolysis of the lipid in the cytoplasm to produce glycerol and fatty acids. This happens because all of the catabolic pathways for carbohydrates, proteins, and lipids eventually connect into glycolysis and the citric acid cycle pathways (see Figure 7.6.2). ... carbohydrates used by plants for energy storage and structural integrity. Carbohydrate ( CHO ) Monosacharides Lipids … The metabolism of both is upset by diabetes mellitus. The simple sugars are galactose, fructose, glycogen, and pentose. THE HANDOUT This handout has five parts: 1. a summary of small molecules commonly used in metabolism for the production and utilization of energy by cells (METABOLIC ENERGY), 2. a short synopsis of the metabolic pathways and hormonal regulation of glucose metabolism (SYNOPSIS OF GLUCOSE METABOLISM), 3. Lorenz , F. W. 1954 , Effects of estrogens on the domestic fowl and applications in the poultry industry . The liver is the second largest organ in the body and has a variety of important functions relating to metabolism and detoxification. Furthermore, the interconversion between principal components alongside inhibition and stimulation are considered in detail.
