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.
Lipids. Fats, oils, waxes, and sterols are collectively known as lipids. Like the carbohydrates, the true fats contain only carbon, hydrogen, and oxygen. The molecules of such a lipid are made up of a glycerol molecule with three fatty acid molecules attached to it. This kind of lipid is also called a triglyceride. An important class of lipids is composed of the phospholipids that make up cell membranes. The class of compounds called steroids are also lipids, and cholesterol is one of the steroids.
