On hydrolysis the products of three will be as follows-
a).Protein- Proteins are the polymers and the monomeric units in them are amino acids thus on hyrolysis protein will give amino acid.
b).Nucleotide – A nucleotide will give three components namely a sugar , a phosphate group and a nitrogen base residue.
c).Lactose – Lactose is an disaccharide which on hyrolysis will give glucose + galactose
