While both pronunciations are found in the dictionary, the actual word of origin for peridot is from the French word peritÃ´t, meaning unclear, because of the numerous inclusions and internal fractures often found within peridot gemstone beads.
Phospholipids are a class of lipids that are a major component of all cell membranes. They can form lipid bilayers because of their amphiphilic characteristic. The structure of the phospholipid molecule generally consists of two hydrophobic fatty acid tails and a hydrophilic head consisting of a phosphate group.The two components are joined together by a glycerol molecule. The phosphate groups can be modified with simple organic molecules such as choline.hey can form lipid bilayers because of their amphiphilic characteristic. The structure of the phospholipid molecule generally consists of two hydrophobic fatty acid tails and a hydrophilic head consisting of a phosphate group.
A phospholipid is composed of two fatty acids, a glycerol unit, a phosphate group and a polar molecule. The phosphate group and polar head region of the molecule is hydrophillic (attracted to water), while the fatty acid tail is hydrophobic (repelled by water).il is a type of lipid known as a triglyceride. Solid triglycerides are called fats and liquid triglycerides are called oils. Photo Credit: Credit: Thomas Vogel/E+/Getty Images.
