Palmitic acid
Palmitic Acid
Palmitic acid (pronunciation: /pælˈmɪtɪk ˈæsɪd/), also known as hexadecanoic acid, is a common saturated fatty acid found in fats and waxes, including olive oil, palm oil, and body lipids.
Etymology
The term "palmitic" is derived from the Latin palma (palm), as the acid was first isolated from palm oil. The chemical suffix "-ic" was added to indicate it is an acid.
Structure and Properties
Palmitic acid is a white, crystalline solid at room temperature. Its chemical formula is CH3(CH2)14COOH. It is soluble in organic solvents but poorly soluble in water.
Biological Role
In biology, palmitic acid is one of the most common saturated fatty acids found in animals and plants. It is a key component in the lipids (fats) that make up cellular membranes and in the myelin sheath that surrounds nerve fibers.
Health Effects
High levels of palmitic acid have been linked to cardiovascular disease due to its contribution to LDL, or "bad" cholesterol. However, it is also an essential part of a balanced diet when consumed in moderation.
