Side chain - Wikipedia

WebThe side chain of the amino acid cysteine is chemically active and can bond with another cysteine. Some amino acids, like lysine, are basic, while others, like glutamic acid, are acidic. Each protein can fold into a certain three-dimensional shape and do a biological job because of the order and interactions between the side chains of the ... WebSome hydrocarbons have only single bonds and appear as a chain (which can be a straight chain or can have branches) of carbon atoms also bonded to hydrogen atoms. These hydrocarbons are called alkanes (saturated hydrocarbons). Each alkane has a characteristic, systematic name depending on the number of carbon atoms in the molecule. In organic chemistry and biochemistry, a side chain is a chemical group that is attached to a core part of the molecule called the "main chain" or backbone. The side chain is a hydrocarbon branching element of a molecule that is attached to a larger hydrocarbon backbone. It is one factor in determining a molecule's properties and reactivity. A side chain is also known as a pendant chain, but a pendant group (side group) has a different definition. bayi asfiksia
