The second step in lipid metabolism is absorption of fats. Short chain fatty acids can be absorbed in the stomach, while most absorption of fats occurs only in the small intestines. Once the triglycerides are broken down into individual fatty acids and glycerols, along with cholesterol, they will aggregate into structures called micelles. Fatty ...
Example of an unsaturated fat triglyceride (C 55 H 98 O 6). Left part: glycerol; right part, from top to bottom: palmitic acid, oleic acid, alpha-linolenic acid. Glycerolipids are composed of mono-, di-, and tri-substituted glycerols, [30] the best-known being the fatty acid triesters of glycerol, called triglycerides. The word "triacylglycerol ...
In either numbering scheme, the position of a double bond in a fatty acid chain is always specified by giving the label of the carbon closest to the carboxyl end. [d] Thus, in an 18 carbon fatty acid, a double bond between C-12 (or ω−6) and C-13 (or ω−5) is said to be "at" position C-12 or ω−6. The IUPAC naming of the acid, such as ...
Many types of neutral fats are possible both because of the number and variety of fatty acids that could form part of it and because of the different bonding locations for the fatty acids. An example is a monoglyceride , which has one fatty acid combined with glycerol, a diglyceride , which has two fatty acids combined with glycerol, or a ...
When a fatty acid oxidation disorder affects the muscles, it is a metabolic myopathy. Moreover, cancer cells can display irregular fatty acid metabolism with regard to both fatty acid synthesis [44] and mitochondrial fatty acid oxidation (FAO) [45] that are involved in diverse aspects of tumorigenesis and cell growth.
Indeed, they can be viewed as a string of beads, with each bead representing a single nucleotide or amino acid monomer linked together through covalent chemical bonds into a very long chain. In most cases, the monomers within the chain have a strong propensity to interact with other amino acids or nucleotides.

In biochemistry, lipogenesis is the conversion of fatty acids and glycerol into fats, or a metabolic process through which acetyl-CoA is converted to triglyceride for storage in fat. [1] Lipogenesis encompasses both fatty acid and triglyceride synthesis , with the latter being the process by which fatty acids are esterified to glycerol before ...
