P3 M2 D2 Unit 13 - describe the primary and secondary structures of proteins, explain the tertiary and quaternary structures of proteins, discuss the relationship between the structure and function of proteins - Extended Diploma
This piece of work is to help with the P3, M2 and D2 Unit 13 Applied Science 2010 - My teacher has signed this assignment off which means that it does meet the grading criteria. Hope it helps, all the best.
Please take note that this document cannot be copied and I would appreciate if you respect...
P3 - describe the primary and secondary structures of proteins:
M2 - explain the tertary and quaternary structures of proteins:
D2 - discuss the relatonship between the structure and functon of proteins:
Primary Structure:
The primary structure results in the condensaton reacton etteen the sequence of amino
acids and the formaton of the peptde ondss When the tto amino acids join together, a
dipeptde molecule is formeds nn the onding of the amino acids, the acid group and the
amine group ind togethers The sequence of the amino acids forms a polypeptdes The
shape of the peptde acc one tould depend on the sequence of the amino acids and the
varia le side chainss Each of the type of the polypeptdes is made up of a unique sequence
of the amino acids thich forms the primary structures The varia le side chains are the ones
thich cause the diference in the amino acidss The amino acid molecule could e seen
elot;
Secondary Structure:
This is then the polypeptde chain is either coiled or pleateds One of the structures thich
the polypeptde chain could coil into is the alphahhelixs This is then the polypeptde chain
coils round in a spiral shape and is then held y the hydrogen onds that form etteen the
hydrogen atom (of the amine group) and the oxygen of the car oxyl group of a diferent
amino acids Another type of structure thich the polypeptde chain could change into is to
fold into etahpleated sheetss The type of folding or coiling tould depend on the varia le
side chain and also the positon of the hydrogen onds holding the amino acid side chains
