The given statement "beta-sheet proteins structures can be stabilized by hydrogen bonding between distant residues on the same polypeptide" is true because it further leads to formation of extended amphipathic sheets.

A typical motif of the typical protein secondary structure is the beta sheet, sometimes known as the "sheet" or "pleated sheet." Beta sheets are made up of beta strands (-strands) that are joined laterally by two or three backbone hydrogen bonds, resulting in a sheet that is typically twisted and pleated.

Extended amphipathic sheets with hydrophobic side chains pointing in one direction and polar side chains in another are generated when many -strands self-assemble and are stabilised by interstrand hydrogen bonding.

Hydrogen bond holds nitrogen bases together.

A hydrogen atom positioned between two other atoms that have a high affinity for electrons interacts with them through a process known as hydrogen bonding. This type of link is stronger than van der Waals forces but weaker than ionic or covalent bonds. Between atoms in the same molecule or in different sections of the same molecule, hydrogen bonds can exist.

The hydrogen atom (FH, NH, or OH) is covalently bonded to one of the pair's atoms (the donor), which is typically a fluorine, nitrogen, or oxygen atom, and receives an unequal share of the donor's electrons due to the donor's high electron affinity. This causes the hydrogen to acquire a slight positive charge. The other member of the pair, usually F, N, or O, has an unshared electron pair, which gives it a little negative charge.

Platelets secrete procoagulants, or clotting factors, which promote blood clotting. They also alter their appearance, activate receptors, and discharge chemical signals.

Platelets play a significant role in hemostasis, the process of halting bleeding at the site of torn endothelium. Except in cases where the obstruction is physically too large, they congregate there and close the opening. To begin with, adhesion occurs when platelets cling to objects outside of the damaged endothelium. Thirdly, they assemble to connect with one another via receptor bridges.
