1.1.3 Carbohydrates serve as recogntion signals in glycoproteins and glycolipids determining cell-cell recognition, intracellular location, and metabolic fates of proteins(thus sugars, like nucleic acids and proteins, are also information rich! But codes unknown) 1.1.4 Carbohydrates (ribose and deoxyribose) form part of the structural framework of rna and dna1.1.3 Carbohydrates serve as recogntion signals in glycoproteins and glycolipids determining cell-cell recognition, intracellular location, and metabolic fates of proteins (thus sugars, like nucleic acids and proteins, are also information rich!
