Most people kill them in two or 3 years. Those that keep them well charged, and Maintain them sometimes get 8 or 10 years, but probably NOT from current productionââââ-MEXICANââââ built Interstate brand batteries, which are , let us say, not quite as good as the old ones.
Lipids ï½ Lipids ï½ Molecules made up of mostly carbon and hydrogen atoms (and some oxygen atoms too) ï½ Nonpolar covalent bonds ï½ Hydrophobic ï½ Insoluble in water ï½ Can be identified by the 2 key parts of their assembly: one glycerol backbone and 3 long carbon chains (fatty acids)â¦ ï½ Far greater than 2:1 H:O ratio.
Lipid macromolecules are made of glycerol. and fatty acids. Lipids are a class of macromolecules that includes fats, phospholipids, and steroids. Lipids are central to several major biological functions, including energy storage, cell membrane structure, and hormone messaging. As in other macromolecules, the molecular components of a basic lipid are. responsible for the unique functions of lipid macromolecules. Lipids are made up. of several smaller molecular structures such as glycerol and fatty acids. Glycerol is an alcohol with three carbons, each attached to an âOH.
