Title: Different Kinds of Fatty Acids: Saturated vs. Unsaturated (Trans + Cis)

Creator: Med School Made Easy

Summary: The type of carbon bond determines whether a fat is saturated or unsaturated. Saturated fats contain single bonds and will try to fit as closely as possible, while unsaturated fats have double bonds, and will not fit as closely together. The atoms of a saturated bond are spaced equally at 90° while the atoms of an unsaturated fat while be spaced at 120°, here we can see why saturated fats are able to stuff themselves closely, while unsaturated fats are unable to. There are two types of unsaturated fats, trans-fats and cis-fats. Trans-fats are linear, and group up easier in cells, while cis-fats have a bend, causing them to not group up as easy. This is important because the fats will be inside the lipid bi-layer of cells. Cis-fats are healthiest for cells as they take up the least space, while trans-fats and saturated fats are the worst for cells, as they are able to take up more space in the cell's lipid bi-layer.
