Lesson Transcript
Instructor: Brekke Peterson Munks
Have you ever craved protein? Have you craved sugar? If you have, you might need to assess your diet and increase your threonine intake. In this lesson, you will understand what threonine is, how it is vital to life and what foods are rich in threonine.

Definition of Threonine

Have you heard of amino acids? These are chemicals that are vital to life, and humans require 20 in order to function normally. Of these 20, there are around 10 that are essential amino acids, meaning we humans cannot make them from other chemicals in our body and must obtain these amino acids from our diet.

The amino acid threonine is one of these essential amino acids and is vital in protein synthesis. Without threonine, proteins do not fold or function properly. The structure of threonine is what makes this amino acid special.

The Structure of Threonine

In general, all amino acids have the same structure: an amino group attached to a hydrogen, a carboxyl group, and a side chain group, denoted by 'R' via a central carbon. The amino and carboxyl groups and central carbon are considered the amino acid backbone and is the same in all amino acids. It is the side chain that is specific to each amino acid.
