1.5.1 Classify amino acids by side-chain properties and explain their acid–base behaviour (pKa, isoelectric point).
Why this video
It clearly groups the standard amino acids by their specific side-chain chemical properties, including branched-chain, aromatic, hydroxyl-, and sulfur-containing groups.
Part of this line
Covers part of this objective. It leaves out: It does not teach the acid–base behaviour of amino acids, such as pKa values, titration curves, or isoelectric point calculations.
Heads up
Be aware that this course groups aromatic amino acids under nonpolar and uncharged polar categories rather than treating them as an entirely separate class.
