CHART CLUE

Stina’s bloodwork over the years shows sky-high inflammatory markers – even between attacks, when she looks fine. It is a chemistry clue everyone explained away. This module introduces the molecular cast of her disease, each member riding in on its biomolecule class.

The Story

Stina’s entire disease comes down to one protein folded the wrong way. Before we can see how a protein gets its shape – or loses it – we need to know what holds moleculesGroups of atoms bonded together. together. Three bonds do most of the work: covalent (sharing), ionic (transfer), and the weak but decisive hydrogen bond that helps fold proteinsLarge molecules made of amino acids with various functions in the body..

From Stina’s chart: Around this point Stina started reading about her own body — teaching herself the chemistry her doctors kept waving off. She didn’t have the diagnosis yet, but she had the stubbornness to keep asking what the molecules were doing.
