# Lípidos

Los lípidos son un grupo de moléculas orgánicas diversas que comparten una
característica común: son insolubles en agua. Estas mo

¿Qué son los lípidos y por qué los necesitas?

Imagínate intentar mezclar aceite con agua - nunca se combinan, ¿verdad? Así funcionan los lípidos: son moléculas que repelen el agua y esto les da propiedades únicas. Incluyen ácidos grasos, fosfolípidos, glícidos y esteroides.

Tu cuerpo usa los lípidos para múltiples tareas importantes. Las grasas almacenan energía para cuando la necesites, forman parte de las membranas celulares que protegen tus células, y te ayudan a absorber vitaminas como la A, D, E y K. También regulan hormonas y ayudan a tu sistema inmunológico.

Como los lípidos no se disuelven en agua, necesitan un "taxi" especial para viajar por tu sangre. Las lipoproteínas los transportan desde el hígado hasta donde se necesiten. Mantener los niveles correctos de lípidos es crucial para evitar problemas cardiovasculares.

¡Dato curioso! Los triglicéridos son los lípidos más comunes en tu cuerpo - están formados por tres ácidos grasos unidos a una molécula de glicerol, como un tridente molecular.

Cómo tu cuerpo procesa los lípidos

Cuando comes alimentos grasos, tu intestino tiene que hacer un truco especial para absorberlos. Este proceso se llama emulsificación - básicamente convierte los lípidos grandes en partículas minúsculas llamadas micelas que sí pueden pasar a través de las paredes intestinales.

Pero cuidado con los excesos. Si consumes demasiados lípidos, tu cuerpo empieza a acumular grasa en el tejido adiposo y aumentan el colesterol y triglicéridos en sangre. Esto puede causar inflamación, problemas cardíacos y resistencia a la insulina.

Los tipos principales de lípidos que debes conocer son: triglicéridos, fosfolípidos, esfingolípidos, colesterol y sus derivados, ácidos grasos libres y ésteres de colesterol. Cada uno tiene funciones específicas en tu organismo.

Consejo de estudio: Recuerda que "lipofóbico" significa que repele las grasas, mientras que "lipofílico" significa que las atrae - esto te ayudará a entender cómo interactúan diferentes moléculas con los lípidos.

I know a lot of apps use fake accounts to boost their reviews but this app deserves it all. Originally I was getting 4 in my English exams and this time I got a grade 7.
