The major difference between a phospholipid, such as those in cell membranes, and a triglyceride is the fact that the phospholipid: O contains phosphate. O does not contain glycerol. O has four fatty acids attached to glucose. is entirely hydrophobic. is nonpolar.
Nucleotides
It is an organic molecule made up of three basic components- a nitrogenous base, phosphate,and pentose sugar. The nucleotides are important for metabolic reactions andthe formation of DNA (deoxyribonucleic acid) and RNA (ribonucleic acid).
Nucleic Acids
Nucleic acids are essential biomolecules present in prokaryotic and eukaryotic cells and viruses. They carry the genetic information for the synthesis of proteins and cellular replication. The nucleic acids are of two types: deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). The structure of all proteins and ultimately every biomolecule and cellular component is a product of information encoded in the sequence of nucleic acids. Parts of a DNA molecule containing the information needed to synthesize a protein or an RNA are genes. Nucleic acids can store and transmit genetic information from one generation to the next, fundamental to any life form.
Lipids are molecules that contain hydrocarbons and make up the building blocks of the structure and function of living cells. Triglycerides and phospholipid is a type of lipid. The triglycerides are also known as storage lipid or fats. Phospholipids are not fats and found in cell membrane.
