When two amino acids join together 1 of 18 How is a polypeptide formed ? When more than two amino acids join together 2 of 18 What is the primary structure ? The sequence of amino acids in a polypeptide chain 3 of 18 The secondary Structure forms which bonds ? Hydrogen bonds 4 of 18 Does the secondary structure form a beta pleated sheet and a alpha helix, true or false ? True 5 of 18 What bonds are formed in a tertiary structure ? Ionic bonds, Disulfide bonds, Hydrophobic bonds, Hydrogen bonds 6 of 18 Does the tertiary structure form a 3D structure, True or False ? True 7 of 18 Quaternary structure ? Some protiens are made up of several different polypeptide chains 8 of 18 What is an ionic bond ? Weak attrations between negative and possitive charges on a molecule. 9 of 18 What is a Disulfide bond ? When two molecules of the amino acid cysteine come close together, forming a bond. 10 of 18 What is a Hydophobic bond ? When hydrophobic groups are close together in the protien they tend to clump together. 11 of 18 What type of protien is Collagen Fibrous 12 of 18 A Fibrous protien is made up of what chains ? Three polypeptide chains, tightly coiled to into a strong triple helix 13 of 18 What bonds link the chains in a Fibrous protien ? Covalent 14 of 18 Is Haemoglobin a globular protien, True or False ? True 15 of 18 What is the structure of Haemoglobin ? It has a curled structure, hydrophilic chains on outside, hydrophobic chains on inside 16 of 18 How are globular protiens adapted to their jobs ? Round and compact, soluble so they are transported in fluids 17 of 18 How are fibrous protiens adapted to their jobs ? Tough and rope shaped, supportive 18 of 18
