Engineering Insulin For Better Treatment of Diabetes: Explores insulin modifications to create slow-, intermediate- and fast-acting insulins.
Introduction to Enzymes: This exploration uses the Enzymes in Action Kit from 3D Molecular Designs to explore terminology associated with enzymes: active site, substrate, product, induced fit vs. lock and key models, competitive and noncompetitive (allosteric) inhibitors. Written as a POGIL, this activity is suitable for online learning.
Substrate Specificity: This exploration was developed to be used with the Substrate Specificity Kit from 3D Molecular Designs. Videos included in this exploration make it suitable for online learning.
Enzymes: Explores how enzymes function, ranging from the enzyme-substrate interactions, enzyme specificity, cofactors and coenzymes, regulating enzymes and enzyme inhibitors.
