Amino Acid Grouping - Basics for Beginners - Biochemistry Lesson

The video tutorial provides an overview of amino acid classification based on chemical properties, focusing on polarity, acidity, and basicity. It introduces mnemonic devices to remember polar and nonpolar amino acids and further categorizes them into sub-groups like branched, aromatic, hydroxyl, and sulfur-containing amino acids. The tutorial emphasizes the importance of these classifications in understanding protein function and activity.

Which of the following is a polar amino acid?

• Histidine

• Glycine

• Valine

• Proline

What is the mnemonic to remember nonpolar amino acids?

• pH tire trip

• VIP mult pH glycine

• VIL
