palmitater

Palmitater, more commonly known in English as palmitates, refers to the salts and esters of palmitic acid, a saturated long-chain fatty acid with 16 carbon atoms (C16:0). Palmitic acid is a major component of animal fats and many plant oils and is produced in biological systems by fatty acid synthesis.

Chemically, palmitates occur when palmitic acid is neutralized with metals to form salts (for example sodium palmitate, potassium palmitate, calcium palmitate) or when palmitic acid forms esters with alcohols. In biochemistry, palmitate can also be covalently attached to proteins in a process called palmitoylation, which helps anchor proteins to cell membranes and modulates their function.

Natural occurrence and metabolism: Palmitates are abundant in both dietary fats and stored fats (triglycerides) in animals and plants. In humans, palmitate is derived from dietary fats and synthesized de novo; it is mobilized and re-esterified into triglycerides for energy storage. Palmitoylation of proteins is a reversible modification that influences protein localization and signaling pathways.

Uses: Industry relies on palmitates as soaps, surfactants, lubricants, and stabilizers. Salts such as sodium, potassium, calcium, and magnesium palmitate are used as emulsifiers, texturizers, and fillers in foods and cosmetics, and certain esters are employed in chemical syntheses and various formulations.

Safety and health: Palmitates are generally regarded as safe when used within established guidelines. Diets high in saturated fats, including palmitate, have been linked with increased levels of LDL cholesterol and cardiovascular risk in some individuals, highlighting the importance of balanced intake.
