Condensation Reaction
A reaction that occurs when two molecules are joined together with the removal of water
1 of 19
Hydrogen Bond
A weak interaction that can occur wherever molecules contain a slightly negatively charged atom bonded to a slightly positively charged hydrogen atom
2 of 19
Hydroylsis Reaction
A reaction that occurs when a molecule is split into two smaller molecules with the addition of water
3 of 19
Monomer
A small molecule which binds to many other identical molecules to form a polymer
4 of 19
Polymer
A large molecule made from many smaller molecules called monomers
5 of 19
Carbohydrates
A group of molecules containing C, H and O
6 of 19
Glycosidic Bond
A bond formed between two monosaccharides by a condenstaion reaction
7 of 19
Lipids
A group of substances that are soluble in alcohol rather than water. They include trigclycerides, phospholipids and cholesterol
8 of 19
Macromolecule
A very large, organic molecule
9 of 19
Phosopholipid
Molecules consisting of glycerol, two fatty acids and one phosphate group
10 of 19
Amino Acids
Monomers of all proteins, and all amino acids have the same basic structure
11 of 19
Peptide Bond
A bond formed when two amino acids are joined by a condenstaion reaction
12 of 19
Primary Structure
The sequence of amino acids found in a molecule
13 of 19
Secondary Structure
The coiling or folding of an amino acid chain, which arises often as a result of hydrogen bond formation between different parts of the chain. The main forms of secondary structure are the helix and th pleated sheet.
14 of 19
Tertiary Structure
The overall three-dimensional shape of a protein molecule. Its shape arises due to interactions including hydrogen bonding, disulfide bridges, ionic bonds and hydrophobic interactions
15 of 19
Quaternary Structure
Protein Structure where a protein consists of more than one polypepetide chain. For exampl, insulin has a quaternary structure
16 of 19
Fibrous Protein
Has a relatively long,thin structure, is insoluble in water and metabolically inactive, often having a structural role in an organism
17 of 19
Globular Protein
Has molecules of a relatively spherical shape, which are soluble in water, and often have metabolic roles within the organism
18 of 19
Prosthetic Group
A non-protein component that forms a permanent part of a functioning protein molecule
