sol:-
isoelectric point = tha point in which amino acid does not move in electric field.means neutral ion formation. so neutral structure of gylcine will be at isoelectric point.
2):- (b)
3):- denaturation :- breaking of secondary and tertiary structure of protein
so, (e) only secondary and tertiary structure of protein.
4):-secondary structure of protein is the result of hydrogen bonding between a backbone -C=O group and a backbone of -N-H group.
5):-teriary structure is stabilised by following interaction:-
6):-two or more polypeptide fit togather in protein of quaternary structure of protein

Review| Constants| Periodic Table Protein structure is conceptually divided into four levels, from most basic to higher order Primary structure describes the order of amino acids in the peptide chain. Secondary structure describes the basic three-dimensional structures, a-helices and B sheets. Tertiary structure describes how the secondary structures come together to form an individual globular protein. Quatemary structure results from individual proteins coming together to form multi-subunit protein complexes Part A Complete the following vocabulary exercise relating to the level...
