Proteins are made up of a series of amino acids. Nucleic Acids (RNA and DNA) are made up of a series of nucleotides. The center of an amino acid is the carbon bonded to four different groups. The fourth group, R, is different for each amino acid. read more

Proteins are large molecules that consist of long chains of amino acids joined together by peptide (#"CONH"#) bonds. The structure of a small protein is. Proteins have polar #"C=O"# and #"N-H"# groups, so they are able to form hydrogen bonds with other molecules and with each other. read more
