Question

Question 2. - Write the main constituents of sebum.​

Answer 1

Answer:

Human sebum consists of squalene, esters of glycerol, wax and cholesterol, as well as free cholesterol and fatty acids (Table 1). Triglycerides and fatty acids, taken together, account for the predominant proportion (57.5%), followed by wax esters (26%) and squalene (12%).

Answer 2

Answer:

Sebum, secreted by the sebaceous gland in humans, is primarily composed of triglycerides (≈41%), wax esters (≈26%), squalene (≈12%), and free fatty acids (≈16%). The composition of sebum varies across species. Wax esters and squalene are unique to sebum and not produced as final products anywhere else in the body.
