Triglycerides are esters of glycerol and fatty acids.

Lactose is milk sugar. It is a disaccharide made up of glucose and galactose.

RNA stands to denote ribonucleic acid. RNA is polymer of ribonucleotides. Uracil is pyrimidine type of nitrogenous base usually found only in RNA.

The pleated sheet (also $\beta$-pleated sheet) is the second form of regular secondary structure in proteins. It is less common than the alpha helix.
