Answer:

Las proteínas son aminoácidos que están unidos por medio de un enlace peptídico y ellas se encargan de dar forma a una célula, de determinar su estructura y de prácticamente dirigir los procesos vitales.

Las funciones de una proteína dependen de su unión a otras moléculas, ya que esa unión determinará la función que hará esa proteína. La unión puede ser a antígenos, al oxígeno, a sustratos, al ADN, a receptores específicos, entre otros.

Algunas funciones específicas son:

Función estructural: proveer estructura y forma a las células y para ello les provee elasticidad y resistencia a los tejidos.

Función enzimática: aquí, las proteínas catalizan las reacciones químicas de las células.

Función hormonal: algunas proteínas actúan como hormonas para controlar niveles de sustancias en las células o controlar algún proceso específico.

Función reguladora: su función es regular ciertos genes y su expresión o regular la división celular.

Función defensiva: ciertas proteínas actúan como anticuerpos para controlar virus y cuerpos extraños dentro del organismo.

Función de transporte: algunas proteínas transportan ciertos elementos como el oxígeno por todo el cuerpo
