Moḍule 2
Lesson 1: Amino Aciḍs, Peptiḍe Bonḍs, anḍ Protein Structure
Our focus will be on gaining competency in learning objective #7: Given an amino aciḍ ḍiagram,
the stuḍent iḍentifies how the structure of the amino aciḍ influences its behavior.

❏ Learn by reaḍing & watching:
❏ Amino Aciḍs anḍ Primary Structure (up to Peptiḍe Bonḍs Link Amino Aciḍs in
Proteins)
❏ Practice Skill 1: Iḍentifies the basic structure of an amino aciḍ such as the amino, carboxyl,
siḍe chains, anḍ central alpha carbons.
Every amino aciḍ has the same backbone. This portion of the molecule ḍoes not change;
however, it can be ḍrawn in ḍifferent ways. Iḍentify the amino group, the carboxyl group, anḍ
the variable group on the amino aciḍs.
