Young scholars read about hamburgers and analyze a healthy diet as well as the importance of nutrition. For this nutrition education lesson, students read the background information about hamburgers and their nutrition facts. Young...

Students explore and explain how mutations in the DNA sequence of a gene may be silent or result in phenotypic change in an organism and in its offspring. They analyze how evolution and biodiversity are the result of genetic changes that...

Students complete a lab activity with polymers to allow them to better understand how to make "observations".  In this science lesson students make measurements and collect data.

Learn the basics of peptide bonds and how different amino acids combine to form different proteins. Also discussed is the difference in function and structure of proteins.

Anything you need to know about amino acids is likely to be available in this learning tool. You can explore the properties, chemical structures, and functions of all twenty amino acids, analyze mutations, and more.

Proteins are linear polymers formed by linking the a-carboxyl group of one amino acid to the a-amino group of another amino acid with a peptide bond. The formation of a dipeptide from two amino acids is accompanied by the loss of a water...

A discussion of the structure and types of amino acids, and of how they combine to form proteins. (Published: October 16, 2010)

[Free Registration/Login may be required to access all resource tools.] In this module, students investigate amino acids, peptide bonds, and proteins. They also have the opportnity to discover the effect of an enzyme on a biochemical...

Amino acids and proteins questions.

Clickable list of links to descriptions and models of 20 amino acids, including classification and structure.

Each amino acid has at least one amine and one acid functional group as the name implies. The different properties result from variations in the structures of different R groups. The R group is often referred to as the amino acid side...

A great site for understanding Amino Acids, the building blocks for protein. Besides a very complete summary, the site includes a complete list of amino acids, a link to basic amino acid structure, a list if atoms in amino acids, and...

Humans need amino acids to exist. Click on each of the necessary twenty listed to see their molecular structures and learn what type they are.

The formation of peptides is nothing more than the application of the amide synthesis reaction. By convention, the amide bond in the peptides should be made in the order that the amino acids are written.

Multiple choice practice questions over glucogenic and ketogenic amino acids.

Lesson explores scientific principles in using eggs as a highly nutritious and versatile food source of protein.

This lesson plan focuses on differences in the amino acid sequence of hemoglobin and myoglobin proteins. They use the number of differences to create a phylogenetic tree.

View 4 common amino acids from all angles with these 3-D interactive molecules. Also, find links to information about other structures.

Read this article to learn more about amino acids and proteins.

Simulate the Western blotting procedure used to identify specific amino-acid sequences in proteins.

Through this activity, students work with macromolecules, proteins and nucleic acids. The focus is on the atomic structure of proteins, how linear polymers are made, and the surface charges of the resulting polymers. . Multiple-choice...

The first thing you might be asking is, "What is an amino acid?" There are more than fifty, and each one of them is a little different. Amino acids are used in every cell of your body to build the proteins you need to survive. All...

Study proteins and amino acids in the science of biology including how they are made using DNA, transcription, and translation and different types of proteins on this site.

Using a bead-bracelet simulation, construct a sequence of amino acids. Then, discover the effects of silent, point, and frameshift mutations.
