Gold has more of a buttery yellow tone while warm golds are much richer. A lot of my clients want to go super light for the summer, so we go a little richer and a little darker and allow those highlights to hybernate during the winter. Your colorist can get you there with a gloss.
Phospholipids are the main constituents of cell membranes. They resemble the triglycerides in being ester or amide derivatives of glycerol or sphingosine with fatty acids and phosphoric acid.
All living things contain organic macromolecules: Lipids, proteins, carbohydrates and nucleic acids. Characteristic for these organic molecules is that they are made up of only a small number of elements: carbon, hydrogen, oxygen, and to smaller amounts nitrogen, phosphorus and sulfur. Lipids are also an important component of the cell membrane. 2  Lipids consist of glycerol and fatty acids tails. 3  The fatty acid tails are long chains of carbon and hydrogen that contribute to the non-polar behavior of fats-they don't mix with (polar) water.
