Hexadecanoate

Hexadecanoate refers to the anion or ester derived from hexadecanoic acid, also commonly known as palmitic acid. Hexadecanoic acid is a saturated fatty acid with a 16-carbon chain, making it one of the most common fatty acids found in animals and plants. When hexadecanoic acid loses a proton from its carboxyl group, it forms the hexadecanoate anion. Esters of hexadecanoic acid are formed when the carboxyl group reacts with an alcohol. These esters are widespread in nature. For example, triglycerides, which are the main component of body fat and vegetable oils, are esters of glycerol with three fatty acids, and hexadecanoic acid is frequently one of these fatty acids. Hexadecanoate is also a component of waxes, phospholipids, and cholesterol esters. In biological systems, hexadecanoate plays a role in energy storage and cell membrane structure. It is also a substrate for various metabolic pathways. The presence of hexadecanoate in food is common, and it is a significant contributor to the caloric content of many dietary fats.
