WebLipids are biological macromolecules. They are essential in living organisms, along with carbohydrates, proteins, and nucleic acids. Lipids include fats, oils, steroids and waxes. They are hydrophobic, meaning they are insoluble in water. However, they are soluble in organic solvents such as alcohols and acetone. WebJan 17, 2024 · Phospholipids consist of a glycerol molecule, two fatty acids, and a phosphate group that is modified by an alcohol. The phosphate group is the negatively-charged polar head, which is hydrophilic. The fatty acid chains are the uncharged, nonpolar tails, which are hydrophobic. gay tours of england https://kusholitourstravels.com
