Lecture

Cell Biology Basics: Macromolecules and Structures

Description

This lecture covers the fundamental concepts of cell biology, focusing on the different types of macromolecules present in cells such as proteins, lipids, DNA, RNA, and sugars. It explains how these molecules interact to form complex structures like membranes, organelles, and protein complexes. The lecture also delves into the hierarchical organization of these structures, from small molecules to atoms, and the importance of weak non-covalent interactions in stabilizing biological polymers. Additionally, it explores the unique properties of lipids, their role in membrane structure and function, and their impact on membrane material properties. The lecture concludes by discussing the diverse functions of lipids in signaling, disease, and synaptic dynamics.
