In solutions of different pif, the structure of amino acidis charigs. m) Dipids ark generally water insoluble, They could be simple fathy an A fatty acid has a carboxyl group attarhed to an R group. The R ont could be a methyl , or ethyl or higher number od groups (1 cartoon to 19 cartoons). For example. palmitse actis has cartoons inciuding cartooxyl cartoon. Arachidonic ackid hac 20 cast atoms inciuding the cartooxy1 carbom. Fatty acids Cound be setiste bond) or unsaturated (with one or more dos bonds). Another simple lipid is glycerol which is trinydroxy propant. liplds have both glycerol and fatty acids. Here the farty actids are hy esterffed with glycerol. They can be then monoglycerides, digyce: and triglycerides. These are also called fats and olls based on mis point. Oils have lower melting point (e.g. gingelly oil) and hence ract as oll in winters. Can you identify a fat from the market? Some la have phosphorous and a phosphorylated organic compound in to These are phospholipids. They are found in cell membrane. Lecits one example. Some tissues especially the neural tissues have lipitist: more complex structures. Living organisms have a number of carbon compound's in tis heterocyclic rings can be found. Some of these are nitrogen bas adenine, guanine, cytosine, uracil, and thymine. When found attank a sugar, they are called nucleosides. If a phosphate group is also esterified to the sugar they are called nucleotides. Adenosine. guans thymidine, uridine and cytidine are nucleosides. Adenylic acid. Uhy : acid, guarylic acid, uridylic acid and cytidylic acid are nucleotides. Ns acids like DNA and RNA consist of nucleotides only. DNA and RNA Fus? as genetic material.
