Figure 3.

Heat map of the characteristic metabolites closely related to centenarians from the longevous region. The color scale correlates with the normalized quantities of the characteristic metabolites in samples: yellower color indicates higher quantities, and bluer color indicates lower quantities. Each row represents one characteristic metabolite, and each column represents one participant. Pink denotes the participants in the LRC group (left side), and blue denotes the participants in the LRE group (right side). It is more obvious to display a marked difference between the LRC group and LRE group, revealing some unique remodeling of amino acid metabolism and lipid metabolism of the healthy centenarians, compared with the elderly people aged 60–70 years. LRC, centenarians in the longevous region; LRE, elderly people aged 60–70 years in the longevous region.
