Ivenika [448]

Question: Describe how a single amino acid substitution causes hemoglobin molecules to stick together. Use what you know about the structure of Hb and HbS, the properties of glutamic acid and valine, and how hydrophobicity causes molecules to behave in water.

Answer:

A Single amino acid must be polar to attract, just like water.

Explanation:

Sickle cell is an genetic illness and it is began by a alteration that arises in the beta sub units of the haemoglobin. Haemoglobin is a tetrameric protein made up of 2 alpha sub units and 2 beta sub units and it is the important part of the blood accountable for oxygen passage. Sickle cell is a illness that consequences from a replacement of a polar amino acid identified as glutamate with a non polar one valine at site six of the beta polypeptide component of haemoglobin. The replacement occurs as a consequence of a alteration in one of the bases in the beta-globin gene from adenine to thymine  . As a outcome of this change, the beta polypeptide chains convert sticky in low oxygen circumstances since the valine sticks out of the chain and interrelates with neighboring non-polar amino acids.

Como se representa la molecula de agua y en cuantas partes
Hitman42 [59]
<span>¡La opinión de un químico sobre el mundo no es tan estrecha como se podría pensar! Sí, empezamos con el átomo, y luego pasamos a las reglas que gobiernan los tipos de unidades estructurales que se pueden hacer con ellos. Se nos enseña tempranamente a predecir las propiedades de la materia en masa de estos arreglos geométricos. Y luego llegamos a H2O, y estamos sorprendidos al descubrir que muchas de estas predicciones están muy lejos, y que el agua (y por implicación, la vida misma) ni siquiera debería existir en nuestro planeta. Pero pronto aprendemos que esta pequeña combinación de tres núcleos y ocho electrones posee propiedades especiales que lo hacen único entre los más de 15 millones de especies químicas que conocemos actualmente. Cuando nos detenemos a reflexionar sobre las consecuencias de esto, la química pasa de ser una ciencia arcana a un viaje de maravilla y placer mientras aprendemos a relacionar el mundo microscópico del átomo con el mundo mayor en el que todos vivimos.</span>
