Aromatic Amino Acid - an overview ScienceDirect Topics

WebAromatic amino acids are relatively nonpolar. To different degrees, all aromatic amino acids absorb ultraviolet light. Tyrosine and tryptophan absorb more than do phenylalanine; tryptophan is responsible for most … WebMay 4, 1999 · Aromatic amino acid hydroxylases are members of a larger group of enzymes that use a mononuclear nonheme Fe center to catalyze a variety of thermodynamically challenging reactions in which O2 is used in the oxidative transformation of substrates. The hydroxylase enzymes are catalytically active in the ferrous oxidation … The hydrophobic effect is the observed tendency of nonpolar substances to aggregate in an aqueous solution and exclude water molecules. The word hydrophobic literally means "water-fearing", and it describes the segregation of water and nonpolar substances, which maximizes hydrogen bonding between molecules of water and minimizes the area of contact between water and non… emily ebaugh
