ester linkages
Nitrogen bases in DNA bond to the deoxyribose sugar molecules that make up the DNA backbone. The bond between the sugar and the base is a covalent bond known as a glycosidic bond.
phosphoester linkages
Ester bond is formed when the carboxyl group of fatty acid combine with the hydroxyl group of glycerol.
The chemical bond connecting one nucleotide with the next one along the nucleic acid chain is a phosphodiester bond. This bond forms between the phosphate group of one nucleotide and the sugar group of the next nucleotide, creating a backbone of alternating sugar and phosphate groups in the nucleic acid chain.
Polyunsaturated fatty acids contain more than one double bond in their chemical structure. These double bonds create kinks in the fatty acid chain, which contributes to their liquid state at room temperature. Examples of polyunsaturated fatty acids include omega-3 and omega-6 fatty acids.
A triglyceride with one fatty acid bound to a glycerol backbone has a structure where the fatty acid is attached to one of the three hydroxyl groups on the glycerol molecule. This forms an ester bond between the fatty acid and the glycerol, creating a molecule with a glycerol backbone and one fatty acid chain attached.
Glycerol forms the backbone of a triglyceride. Three free-swinging fatty acid chains bond to it, forming a triglyceride, the most common type of lipid.
The primary bond present in lipids is the ester bond. It connects the fatty acids to the glycerol backbone in triglycerides, phospholipids, and glycolipids.
fatty acids containig single bond contains more hydrogens and are saturated and fatty acids containing double bond are unsaturated and have less hydrogen then single bond containig fatty acids
a non-polar covalent bond
In the structure of DNA, a phosphate base is connected to a sugar molecule through a covalent bond. This bond forms the backbone of the DNA molecule, with the phosphate-sugar backbone providing stability and structure to the double helix shape of DNA.
Phosphate backbone
Nitrogen bases in DNA bond to the deoxyribose sugar molecules that make up the DNA backbone. The bond between the sugar and the base is a covalent bond known as a glycosidic bond.
A phosphodiester bond holds the deoxyribose sugar and phosphate group together in a DNA molecule. This bond forms between the 3' carbon of one deoxyribose and the 5' carbon of the adjacent deoxyribose in the DNA backbone.
A peptide bond can be recognized in a molecule by looking for a specific bond between the carboxyl group of one amino acid and the amino group of another amino acid. This bond forms the backbone of proteins and can be identified by its characteristic double bond between carbon and nitrogen atoms.
ESTER BOND
Normal dietary fats, such as butter, are made from 3 fatty acids bonded to a glycerol 'backbone'. Because Olestra is made from sucrose, it can bond with six, seven, or eight fatty acids. The resulting shape is much larger and irregularly shaped to fit through intestinal walls.
