current research indicates that melanin may possibly provide a protecting position in addition to photoprotection.[seventy three] Melanin has the capacity to efficiently chelate metallic ions as a result of its carboxylate and phenolic hydroxyl groups, often far more competently in comparison to the strong chelating ligand ethylenediaminetetraacetate (EDTA).

Not all the effects of pigmentation are advantageous. Pigmentation improves the heat load in incredibly get more info hot climates, and dark-skinned individuals take in thirty% a lot more warmth from sunlight than do incredibly light-weight-skinned people today, Whilst this aspect may very well be offset by extra profuse sweating.
