Learners read this review of chemical hair bonds after completing learning objects on the peptide, disulfide, salt, and hydrogen bonds. Students may e-mail their quiz answers to their instructor.
In this animated object, learners examine the formation of ester bonds in the synthesis of lipids using triglyceride biosynthesis as an example. Ester bond formation is described as a dehydration synthesis reaction.
In this animated object, students examine what happens when electrons share molecules.
Students read about the process of hair growth beginning with the joining together of amino acids.
In this animated object, learners examine the formation of peptide bonds through dehydration synthesis.
In this animated object, learners examine how changes in pH affect the salt bonds in strands of hair.
