what are secondary proteins
In biochemistry and structural biology, protein secondary structure is the general three-dimensional form of local segments of proteins. Secondary structure can be formally defined by the pattern of hydrogen bonds of the protein (such as alpha helices and beta sheets) that are observed in an atomic-resolution structure.he rough secondary-structure content of a biopolymer (e.g., this protein is 40% Î±-helix and 20% Î²-sheet .) can be estimated spectroscopically. For proteins, a common method is far-ultraviolet (far-UV, 170â250 nm) circular dichroism.
