WebJul 6, 2024 · The term carbonyl refers to the carbonyl functional group which is a divalent group consisting of a carbon atom with a double-bond to oxygen, C=O. Carbonyl also … Major families of biopolymers are polysaccharides (carbohydrates), peptides, and polynucleotides. Many variants of each are known. Proteins are characterized by amide linkages (-N(H)-C(O)-) formed by the condensation of amino acids. The sequence of the amino acids in the polypeptide backbone is known as the primary structure of the protein. Like al…
WebFunctional groups are found along the “carbon backbone” of macromolecules which is formed by chains and/or rings of carbon atoms with the occasional substitution of an element such as nitrogen or oxygen. Molecules with other elements in their carbon backbone are substituted hydrocarbons. WebAlpha-helices are formed by hydrogen bonding involving an alpha carbon-bound amine group's hydrogen and the carbonyl group attached to the amino acid four amino acids upstream.
