Identify the true statements regarding disulfide bridges (disulfide bonds). disulfide bridges have a stabilizing effect on proteins. disulfide bridges are formed by an irreversible oxidation reaction. disulfide bridges can exist between two amino acid residues on different chains. a disulfide bridge forms between two cysteine residues. disulfide bridges are important to primary and secondary structure.

Option (1), (2), and (4).

Explanation:

A disulphide bond is also known by the name disulphide bridge. This is a type of  a covalent bond by the oxidation of the sulfhydryl groups. This bond is important for the folding of proteins.

Disulfide bonds is important for the stabilization of protein. Their main effect is to stabilize and the proper functioning of protein. The disulfide bond is present between the two amino acids of the different polypeptide chain. The amino acids that contain cysteine residues has the ability to form this bond.

Thus, the correct answer is option (1), (2), and (4).

The answer is 1,3,4

Explanation:

I got it right on the homework

you dont brother god luck

answer: ice crystals in air

the water from the water body or another source of water gets evaporated as water vapor as an effect of heat on water. these water vapor rises in the upper layers of the earth atmosphere under high atmospheric pressure. the atmospheric pressure of these water molecules starts to decrease due to the effect of cold air. the invisible water vapor condenses into visible water droplets and ice crystals.these ice crystals and water droplets being less denser than the surrounding air floats on air as clouds.
