WebThe beta sheet, (β-sheet) (also β-pleated sheet) is a common motif of the regular protein secondary structure.Beta sheets consist of beta strands (β-strands) connected laterally by at least two or three backbone hydrogen bonds, forming a generally twisted, pleated sheet.A β-strand is a stretch of polypeptide chain typically 3 to 10 amino acids long with … WebThe quaternary structure of a protein is the association of several protein chains or subunits into a closely packed arrangement. Each of the subunits has its own primary, secondary, and tertiary structure. The subunits are held together by hydrogen bonds and van der Waals forces between nonpolar side chains.

WebDisulfide bonds are important in maintaining what level of structure in proteins? Tertiary Which type of macromolecule is involved in catalyzing reactions, transporting molecules, motility, maintaining cell framework, sensing and responding to external stimuli, and regulating gene expression? WebNov 27, 2024 · Secondary Structure. Stretches or strands of proteins or peptides have distinct, characteristic local structural conformations, or secondary structure, dependent on hydrogen bonding. The two main types of secondary structure are the α-helix and the ß-sheet. The α-helix is a right-handed coiled strand. emily mcintyre photography
