LEARN MORE ************** To learn more about this topic, start your googling with these keywords: - Amino acids: are organic compounds that contain amino (–NH2) and carboxyl (–COOH) functional groups, along with a side chain specific to each amino acid. - Proteins: are macromolecules composed of one or more long chains of amino acid residues. Most proteins fold into unique 3D structures. The shape into which a protein naturally folds is known as its native conformation. - Alpha helix (α-helix): is a common motif in the secondary structure of proteins and is a right hand-helix conformation in which every backbone N−H group hydrogen bonds to the backbone C=O group of the amino acid located four residues earlier along the protein sequence. - Beta sheet (β-sheet): is a common motif of the regular protein secondary structure and consists of beta strands (β-strands) connected laterally by at least two or three backbone hydrogen bonds, forming a generally twisted, pleated sheet. - Ribbon diagrams: are 3D schematic representations of protein structure that shows the overall path and organization of the protein backbone in 3D. Ribbon diagrams are generated by interpolating a smooth curve through the polypeptide backbone. α-helices are shown as coiled ribbons or thick tubes, β-strands as arrows, and non-repetitive coils or loops as lines or thin tubes.
