how are they formed
long chained sequence of protiens, carboxyl group reacts witha fatty acid group in a condenstation recation fromina peptide chain
3 of 9
protein structure
primary :long chain of amino acids held together by peptide bond, secondary : due to formation of hydrigen bonds alpha helisx and beta pleated sheet forms, tertairy: 3d shape with ionic, disulphide bridges and hydrigen bonds
4 of 9
two types of protein
fibourous and globular

faciliated diffusion
6 of 9
two types of proteins
intrinsic and extrinsic

what is channel protien
channell proteins allows small charged particles such as ions through the membrane, the protein is specfiic to one type of ion.
