What is the primary compound found in secretions from sebaceous glands?

The primary compound found in secretions from sebaceous glands is lipids. These glands produce an oily substance known as sebum, which is primarily composed of various types of lipids, including triglycerides, wax esters, and free fatty acids. Sebum plays a crucial role in maintaining skin hydration, preventing hair from becoming dry and brittle, and providing a barrier against bacteria and fungi.

The lipid content is significant because these compounds help to create a protective layer on the skin, which is essential for overall skin health. By understanding that lipids are the key component in sebaceous gland secretions, one can appreciate their importance in dermatology and forensic science, particularly in the context of latent prints, where skin secretions may impact the preservation and analysis of fingerprints.
