Peptide bonds
a peptide bond is the covalent bond that holds two amino acids together.
The monomers of DNA, called nucleotides, are linked together by phosphodiester bonds. These bonds form between the phosphate group of one nucleotide and the sugar group of the next nucleotide in the DNA strand.
Peptide bonds
Keratin disulfide bonds are strong chemical bonds that link together the protein molecules in hair. These bonds provide strength and structure to hair by forming a network that holds the protein molecules tightly together. This network helps hair maintain its shape and resist damage from stretching or bending.
Bonds hold atoms together. There are hydrogen bonds, ionic bonds, and covalent bonds.
two hydrogen bonds holds adenine and thiamine together and three hydrogen bonds holds guanine and cytocine.
Generally hydrogen bonds between the different base pairs holds the double helix together.
