The facts on the card
The card carries these facts from its Wikipedia article.
- It contains an α-amino group, a carboxylic acid group, and an imidazole side chain, classifying it as a positively charged amino acid at physiological pH.
- Initially thought essential only for infants, it has now been shown in longer-term studies to be essential for adults also.
- It is encoded by the codons CAU and CAC.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Histidine article was read about 65,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 70 and blocks with 69: each hit it takes is cut by 28 %.
