Biochemistry Assessment - Assignment Example his increase in boiling point is due to higher number of carbons in butyric acid as compared to acetic acid; number of carbons is one of the criteria on which boiling point depends. Aldehydes and ketones both contain carbonyl group (C=O). When C=O is at the end of carbon chain, and carbon has two single bonds, one with other carbon and one with a hydrogen, then it’s an aldehyde. Vanillin is a phenolic aldehyde which is added to beverages and foods as a flavoring agent. It’s also found in French fries (trans fats). 9.Sucrose and honey are commonly used sweeteners.   Suppose you had a sweet-tasting water solution that contained either honey or sucrose.   How would you chemically determine which sweetener was present? For sucrose, resorchinol (1, 3-benzenediol) can be used to detect for the presence of sucrose in the solution. Resorchinol indicator solution is prepared by adding 0.05 g of reagent-grade resorchinol in 100 ml of HCl solution. 1 ml of freshly prepared indicator solution is mixed with 5 drops of 1 % unknown solution and heated to boiling point. If it turns to cherry red color after a few minutes, it indicates presence of sucrose, if it turns to other colors like yellow or salmon then sucrose is not present. Denaturation of proteins results in disruption and destruction of secondary and tertiary structures. As the process is not that much strong to break peptide bonds, so primary structure (sequence of amino acids) remains intact. However, alpha-helix and beta sheets are disrupted resulting in random shapes. 1. Messenger RNA (mRNA) is responsible for carrying the genetic information which is copied from DNA. This information is copied as a series of three-base code â€Å"words,† which are specific for a particular amino acid. 2. Transfer RNA (tRNA) has an important role of understanding and interpreting the genetic code carried by mRNA. In this regard, each amino acid has a specific type of tRNA. This
