Answered by The Community. Making the world better, one answer at a time. No, starch is held together by a-1,4 glycosidic linkages. Carbohydrates, starch in this case, form glycosidic bonds while proteins (amino-acids) are the ones that form peptide bonds.!!!
Hydrogen bonds hold the nitrogen bases in complementa â¦ ry DNA and RNA strands. Polypeptide bonds are formed between an amide and ketone, and these join amino acids in proteins. However, they do not hold nitrogen bases together.
