Las proteínas tienen 4 niveles de estructura:

  1. Estructura primaria: es la secuencia de aminoácidos que forman la cadena peptídica de la proteína.
  2. Estructura secundaria: es el plegamiento de la cadena por unión con aminoácidos de la misma cadena dándole a la proteína la forma de alfa hélice o de lámina plegada.
  3. Estructura terciaria: la estructura secundaria de la proteína se pliega dando a la proteína una estructura globular, la cual hace a la proteína soluble, o fibrilar, la cual hace a la proteína insoluble.
  4. Estructura cuaternaria: dos o más proteínas con estructura terciaria se unen.

Si la xerodermia afecta la secuencia de aminoácidos, afecta la estructura primaria de la proteína ya que esta es el orden en que los aminoácidos se juntan para formar la cadena peptídica.
