#uncat **Fatty acids** are the building blocks of [[Fat|fats]], just like amino acids are the building blocks of [[Proteins|proteins]]. An essential fatty acid is the one your body needs but can't assemble. Linoleic acid (линолевая кислота), found in vegetable oils, is essential. Two others: linolenic acid (линоленовая кислота) and arachidonic acid (арахидоновая) are in a somewhat ambiguous position: you can't make them from scratch, but you can if you have enough linolenic acid on hand. ## Types ![[Pasted image 20241219031545.png]] ![[Pasted image 20241219031612.png]] ## In food ![[Pasted image 20241219031909.png]] ![[Pasted image 20241219032016.png]] Possible solution to the problem of hydrogenated fatty acids is plant **sterols** and **stanols**. Plant sterols are natural compounds in the oils in grains, fruits, and vegetables. They are known to reduce blood [[Cholesterol|cholesterol]]. Stanols are compounds created by adding hydrogen atoms to sterols from wood pulp and other plant sources. They are known to reduce blood cholesterol.
