QUE SON LA BIOMOLECULAS​
DIA [1.3K]

Son consideradas biomoléculas aquellas moléculas que forman parte de los organismos vivos.  

Las moléculas son las unidades físicas de la materia, que se forman a partir de la unión de dos o más átomos agrupados a través de enlaces químicos.

Las biomoléculas se clasifican en inorgánicas u orgánicas.

• Las biomoléculas inorgánicas se encuentran ampliamente en la atmósfera. El agua, algunas sales como el cloruro de sodio, y gases como el oxígeno, son ejemplos de biomoléculas inorgánicas.  

• A las moléculas como azúcares, proteínas, combustibles, entre otras, las cuáles contienen átomos de carbono, hidrógeno, oxígeno y a veces nitrógeno se les llama moléculas orgánicas.

Cuando las moléculas orgánicas forman parte de la materia viva, se les conoce como biomoléculas orgánicas, las cuales incluyen fundamentalmente glúcidos, lípidos, proteínas y ácidos nucleicos.

Por lo tanto, podemos concluir que las moléculas (compuestos que se forman a partir de los elementos químicos) que se encuentran formando los seres vivos se conocen como biomoléculas y se clasifican en inorgánicas u orgánicas.
