WebMost of the cholesterol is carried to the plasma membrane, where it modulates membrane fluidity and maintains barrier between cell and environment. However, cholesterol is also sent to other organelles. Some of them are a part of the secretory pathway (e.g., the Golgi complex and lysosomes), and they receive cholesterol by vesicular transport. WebThe principal components of the plasma membrane are lipids (phospholipids and cholesterol), proteins, and carbohydrate groups that are attached to some of the lipids …
