What are the bond linking monomers for each of these biological macromolecules: Protein, Carbohydrate, Nucleic Acid, and Lipid.
Protein - Peptide bond
Proteins are formed by when the amino acids(Monomers) are linked by a covalent bond known as a peptide bond. In peptide bond carboxyl group of one monomer is linked with the amino group of another monomer and a molecule of water is lost.
Carbohydrate - Glycosidic bond.
In glycosidic bond monosaccharides(monomers) are linked together and a molecule of water is released. OH group of both the monomers are linked together which results in dehydration. It is a type of covalent bond.
Nucleic acid - Phosphodiester bond
In phosphodiester bond nucleotides are linked together. The bond is formed between OH of 3' carbon of one monomer sugar and OH of a phosphate group present 5' carbon of the sugar of another monomer. In the process water is lost. It is also a type of covalent bond
Lipid - Ester linkage.
Like every other linking bonds of biomolecules, it is also a dehydration reaction that means a water molecule is lost and it is also a covalent bond.
