The lifetime of the purple intermediate formed from D-amino acid oxidase [D-amino acid: O2 oxidoreductase (deaminating), EC 1.4.3.3] and a neutral D-amino acid under anaerobic conditions was measured with a series of neutral D-amino acids. The lifetime increases with increase in the number of carbons in the side chain of the amino acid up to 4-5 atoms and then decreases with further increase in the number of carbons. This suggests that the hydrophobicity of the alkyl group of the neutral D-amino acid determines the lifetime of the purple intermediate unless a steric effect occurs.
在厌氧条件下，用一系列中性D - 氨基酸测定了由D - 氨基酸氧化酶[D - 氨基酸：O2氧化还原酶（脱氨基），EC 1.4.3.3]和中性D - 氨基酸形成的紫色中间体的寿命。寿命随着氨基酸侧链中碳原子数增加至4 - 5个原子而增加，然后随着碳原子数进一步增加而减少。这表明，除非发生空间效应，中性D - 氨基酸烷基的疏水性决定了紫色中间体的寿命。
