Lipid metabolism is the synthesis and degradation of lipids in cells, involving the breakdown or storage of fats for energy and the synthesis of structural and functional lipids, such as those involved in the construction of cell membranes. In animals, these fats are obtained from food or are s...
Lipids are used by organisms for energy storage, as a signalling molecule (e.g.,steroid hormones), as intracellular messengers, and as a structural component of cell membranes. The fat-soluble vitamins (A, D, E, and K) are isoprene-based lipids that are stored in the liver and fat. Som...
The major biomolecules that we know of (proteins, DNA, lipids) are actually polymers of smaller monomeric units. For example, proteins are the polymers of amino acids, which are the monomers. Answer and Explanation:1 A polysaccharide is the term used to describe a carbohydrate polymer. For exa...
Lipoproteins Definition, Structure & Function from Chapter 9/ Lesson 4 71K Learn to define what lipoproteins are. Discover the lipoprotein structure and composition, and see the function of lipoprotein and how chylomicrons transport lip...
A lipid is a soft, fatty, waxy substance that does not dissolve in water and which moves through your bloodstream. There are two primary categories of lipids: cholesterol andtriglycerides. Cholesterol is further divided into two main types: ...
lipids within liver cells. In addition, small fat droplets collect around hepatocytes in areas filled with venules, proceeding toward the portal tracts. The first form of ALD, i.e., pure AFLD, may not be a benign condition every time. In fact, when retrospectively analyzing patients with a...
LDL, or low density lipids, are "bad" cholesterol. It is important to differentiate between LDL and HDL cholesterol, since...
Nile Red is a fluorescent dye (see absorption curve, dashed line, and emission curve, below) widely used to localize and quantify lipids but it can also selectively bind to most plastics, allowing them to be identified by looking at the fluorescence in both the green as well as in the ...
Definition: What are Viruses?First described by Martinus Beijerinck, a Dutch scientist, in 1899, viruses are obligate intracellular parasites that are often described as particles. Unlike many other unicellular organisms, viruses can only replicate within living cells (e.g. in bacteria, plant and ...
Describe the role and function of carbohydrates, lipids, proteins, and fiber to maintaining a healthy and balanced diet. Describe the substrates for gluconeogenesis. What are the products of fermentation? Describe how a polysaccharide can make its way in the form of glucose in the blood. ...
