well the amino acids each have an R group. an R group can determine wheter teh AA is polar, non-polar or charged. the bonds (disulfide bridge/ionic/H bonds) that form between the neighbouring AAs when they fold into its 3D structure are dependent on the R groups and their position in the sequence. for eg. a polar amino acid in one area of the sequence that formed a hydrogen bond with a another polar amino during the tertiary structure stage acid vs. a charged aa forming an ionic bond with another charged amino acid
--> the shape and function would totally be different!
Intriguing! A pigment is not a chemical description but a tendency to change wavelengths into selective wavelengths, so all colour has some pigment!
i didnt noe that too! :O
This is the chlorophylls structure: a porphyrin ring (the head of the molecule with a central mg ion) attached to a hydrocarbon tail (interacts with hydrophobic regions of proteins in the thylakoid membrane)
