per item
There are 20 different amino acids most commonly occurring in nature. Each of them has its specific characteristics defined by the side chain, which provides it with its unique role in a protein structure. Sample the Mega Molecules learning activities in your classroom with our free Glycine Model Set. Shipping charges apply.
Teaching Tip - Students may order their own amino acids and assemble the amino acids into a huge "protein" for display in the classroom! Instructions for putting the amino acids together to form a protein are found in the modeling activity for FC95, Proteins Model Set, listed in the Biochemistry category.

Each amino acid is composed of a central carbon bonded to four groups. The first three of these groups are the amino group, the carboxyl group, and a hydrogen atom. The fourth group, often signified by R, completes the amino acid. Each of the 20 amino acids has a unique R group. There are basically four different classes of amino acids determined by different side chains: (1) polar, (2) acidic, (3) basic, and (4) non-polar.

The simplest, and smallest, amino acid found in proteins is glycine for which the R-group is a hydrogen atom (H).
