KnowraProteinLinked fromLinked fromThe 63 pages that link to Protein, each with the reason it gives.All 63Broader topic 6Related 20Narrower topic 28Compared with 9DNACompared with: Proteins carry out many cellular functions, while DNA stores hereditary sequences.RNACompared with: Proteins provide most cellular catalysis, whereas RNA can also catalyze reactions.CarbohydrateCompared with: Proteins are another major biomolecule class, built from amino acids rather than sugars.Nucleic acidCompared with: Proteins are gene products whose amino acid sequences differ chemically from nucleotide sequences.LipidCompared with: Proteins are built from amino acids, unlike the structurally diverse lipid group.RNA world hypothesisCompared with: Their dominance in modern catalysis poses the question of how RNA-based chemistry gave way to proteins.PeptideCompared with: Proteins are generally longer and structurally more elaborate, but the boundary with peptides is not universal.MelamineCompared with: Melamine can mimic protein in total-nitrogen tests but is not a protein or a nutritional substitute.Alternative biochemistryCompared with: Alternative biochemistries may use different polymers or monomers instead of protein machinery.
