【正文】 PROTEIN STRUCTURES To see some of these images in 3D you will need a Blue or Cyan filter on your left eye and a Red or Magenta filter on your right eye. (Experiment with the filters for best effect) Left Right AMINO ACID Proteins are formed from Amino Acids joined in a chain All Amino Acids have an alkaline Amino group (NH2) and an acid Carboxyl group (COOH) There are just 20 naturally occurring Amino Acids, each with a different R group. Amino end Carboxyl end The 20 naturally occurring Amino Acids. The shaded box is the same for all Amino acids. It is an single Carbon atom bonded to an Amino group, a Carboxyl Group and a Hydrogen atom... R NH2 C COOH H Disulphide Bridge The bonds between Amino Acids are … Peptide Bonds Peptide bonds are formed by Condensation and broken by Hydrolysis A PEPTIDE BOND O H C N One Amino Acid Another Amino Acid ?Formed by Condensation ?Broken by Hydrolysis (Heat in acid condition) PRIMARY STRUCTURE This diagram shows the primary structure of PIG INSULIN, a protein hormone
