Similar to the plum, peaches and nectarines also have higher TAC in the skin than in the flesh. They also contain moderate levels of carotenoids and ascorbic acid. Peaches and nectarines are orange and yellow in color, which can be attributed to the carotenoids present. Ascorbic acid is important in hydroxylation reactions, such as collagen synthesis, "de novo" synthesis of bone and cartilage, and wound healing. Ascorbic acid is vitamin C, which is essential for repairing tissues and absorbing iron.
