1 Lipidos

2 Los lípidos son compuestos solubles en solventesno polares y tienen una gran variedad de estructuras y funciones

3 Fatty Acids Are Carboxylic Acid with Hydrocarbon Chains

4 Triacilgliceridos Un triacilglicerido glycerol Ácido grasoUna grasa o un aceite glycerol Ácido graso

5 Grasas son triacilgliceridos de estado sólido o semisólidoa temperatura ambiente

6 Los aceites a temperatura ambiente son líquidos

7 Oxidation of Polyunsaturated Fats and Oils by O2

8 Fosfoacilgliceroles Son los componentes mayoritaros de las membranascelulares El grupo OH terminal del glicerol es esterificado con acido fosfórico

9 Fosfoacilgliceroles son clasificados como fosfolípidos

10 Phosphoacylglycerols form membranes by arrangingthemselves into a lipid bilayer Saturated fatty acids decrease membrane fluidity because their hydrocarbon chains can pack closely together Unsaturated fatty acids have the opposite effect

11 Esfingolípidos Ellos contienen esfingosina en vez de glicerolSe encuentran en membranas

12 Prostaglandinas Prostaglandins are synthesized from arachidonic acidThey are responsible for regulating a variety of physiological responses Name in the format PGX, with X designating the functional groups of the five-membered ring Esqueleto de prostaglandina
