Can Phospholipids Be Saturated or Unsaturated?

Phospholipid tails can be saturated or unsaturated. ... Saturated tails have no double bonds and as a result have straight, unkinked tails. Unsaturated tails have double bonds and, as a result, have crooked, kinked tails.

Are phospholipids made of saturated or unsaturated?

Phospholipids are amphiphilic. They have a polar head and two hydrocarbon tails, which are nonpolar. The phospholipids that make up the cell membranes of plants, bacterial or animal cells often have fatty acids tails. Of these two fatty acid tails one is unsaturated (contains double bonds) and the other is saturated.

Are there saturated phospholipids?

The second factor that leads to fluidity is the nature of the phospholipids themselves. In their saturated form, the fatty acids in phospholipid tails are saturated with bound hydrogen atoms; there are no double bonds between adjacent carbon atoms. This results in tails that are relatively straight.
