Biological Molecules Flashcards
What’s an example of a monosaccharide
They contain 1 simple sugar such as pentose or hexose
What’s an example of disaccharide
It’s a 2 unit sugar and maltose and sucrose are an example
What’s an example of a polysaccharide
It’s many sugar units and examples are starch, glycogen and cellulose
What are the products of oxidisation of glucose in the body
Carbon dioxide, water and atp
What’s a polymer
It’s a very large molecule made up of lots of small repeated units such as starch and proteins made from amino acids
What’s a primary protein structure
A primary structure is the sequence of amino acids in the chain
What’s a secondary structure of a protein
It’s the arrangement of short sections of the chain
What’s a tertiary structure of a protein
It’s the way in which the chains are folded and twisted in an active protein
What is the haemoglobin protein
It’s found in red blood cells and enables them to carry oxygen
What’s an enzyme protein
