Glycosidic bond

Hopefully it will help u ✌️✌️

Answer 2

The enzyme nuclease hydrolyses phosphodiester bonds of polynucleiotide chain of DNA.

Explanation:

• Definition of the phosphodiester bond.
• The sugar-phosphate-sugar backbone of DNA and RNA is founded by links between two sugar groups and a phosphate group.
• Two nucleotides are linked together by a glycosyl bond (between phosphoric acid and two sugar molecules) to produce the nucleotide polymers DNA and RNA.
• A hydrogen atom is placed between two other atoms with a high affinity for electrons, producing a hydrogen bond that is weaker than an ionic or covalent link but stronger than van der Waals forces.
• The glycosidic bond is a kind of chemical bond.
• The hemiacetal group of a saccharide molecule and the hydroxyl group of some organic component form a covalent link (e.g., an alcohol).
• The Maillard reaction occurs when food is cooked at high temperatures.
• Non-enzymatic brown is a chemical process between an amino group and a reducing sugar that is important in the food business.
• Proteins are linear polymers generated by a peptide bond connecting the -carboxyl group of one amino to the -amino group of another amino acid (also called an amide bond).
