Define
monomer
a simple molecule that is used as a basic building block for the synthesis of a polymer
Define
primary structure protein
the basic sequence of amino acids bonded by peptide bonds in a polypeptide chain
What is a
secondary structure protein
a polypeptide where
* the weak negatively charged nitrogen and oxygen atoms
interact with
* weak positively charged hydrogen atoms
to form H bonds
What is a
tertiary structure protein
the further coiling of the secondary structure of a polypeptide including the bonds formed between side chains
What is a
quartenary structure
more than one polypeptide chain interacting with each other as a functional macromolecule
Define

2.4 Water
the heat required to change one mole of liquid into one mole of gas
Define
specific heat capacity of water
2.4 Water
the amount of heat energy required to raise the temperature of 1kg of water by 1℃
What is a
polymer
a long chain of small, repeating subunits
What is a
macromolecule
a very large molecule made up of many subunits
What is a
monosaccharide
a single monomer subunit of a sugar
What is a
disaccharide
a sugar consisting of two monosaccharides joined by a glycosidic bond in a condensation reaction
