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.
There are different types of lipids, but what they all have in common is that they do not dissolve in water. Fatty acids are lipids made of long chains of hydrogen and carbon. Waxes are made of fatty acids and alcohols. Sphingolipids may have fatty acids, alcohol, phosphate and nitrogen, while triacylglycerides are made of a substance called glycerol and three fatty acids. Fats are triacylglycerides that are solid at room temperature, but when the triacylglycerides are liquid, they are called oils.
