Download file to see previous pages 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 “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 ...Download file to see next pagesRead More

...? Clinical Cases; Questions and Answer Part Case Study Glycaemic status Question Blood glucose monitoring has been an important tool in the effective management of out-patients with diabetes. This tool which entails self monitoring of blood glucose level in a specified period has been designed to help in glycaemic control and lowered the risk associated with high blood sugar level. Considering the result of the biochemical analysis done for the patient, it can be concluded that the patient has not been monitoring his blood sugar effectively. Each of those outlined results point towards different analysis and help in the assessment of a poorly controlled blood sugar. Fasting blood glucose clearly shows a higher value that...

Clinical Biochemistry Assignment Other (s) Clinical Biochemistry Assignment Enzymes COMT (Catechol-O-methyltransferase) COMT (Catechol-O-methyltransferase) is an important enzyme that acts as a catalyst in the transfer of methyl group from S-adenosylmethione to catecholamines including epineprhrine, neurotrsnmitters, dopamine and nonepineprhrine (BRENDA 2). The process of O-methylation normally occurs in one of the degenerative pathways of catecholamine transmitters. In this regard, the pathways include dopamine degradation and betaxanthin biosynthesis. Encoded by COMT gene, Catechol-O-methyltransferase also plays a critical role in the metabolism of many catechol drugs used in the treatment of hypertension, Parkinson’s disease... Clinical...

Pyruvate dehydrogenase complex is an important enxyme complex that particularly works by transforming pyruvate into acetyl-CoA through a process known as pyruvate decarboxylation (Smolle 196). The resultant product (acetyl-CoA) is then normally used during the citric acid cycle to enhance cell respiration. Structurally and...

Biochemistry discussions

...BIOCHEMISTRY DISCUSSIONS Assignment 10 November The Central Dogma of Biochemistry and How it Affects Humans The central dogma of biochemistry states that the stream of information in living organisms starts from DNA to RNA and finally to proteins (Mikulecky, Gilman & Peterson, 2008). This means that the existence of information relies on its movement from the genetic material (DNA) to RNA (coded genetic information) and finally to proteins. The three steps involved in the central dogma are replication, transcription, and translation. Replication is the copying of genetic material, which leads to the establishment of more than one copy of DNA. Transcription is the process that produces RNA from DNA, and translation is the synthesis...

Biochemistry

...Biochemistry Case of In normal muscle activity, glucose is transported through blood stream from liver to muscles. This glucose is actually the product of glycogenolysis and provides muscle with Adenosine tri-phosphate (ATP) which is the basic energy currency for the cell. Pyruvate is the end product of this process when energy is sufficient but during the time of hypoxia this pyruvate goes into lactic acid cycle. It is conversion of pyruvate into lactate to produce extra amount of energy which is 2 molecules of ATP’s. The enzyme involved in this process is called lactate dehydrogenase. This lactate is normally takes back to liver where it would convert back into pyruvate and glucose through process of gluconeogenesis....

Biochemistry Assignment

...Biochemistry Assignment How glutamic acid (glutamate) act as an excitatory neurotransmitter Amino acid group contains the universal excitatory transmitter called Glutamate.Glutamate acid is the most dominant excitatory transmitter in the central nervous system. Neurons from glucose are responsible for the synthesis of glutamate. It plays its role by opening sodium Na and potassium K channels. Upon its release, glutamate is conveyed from the synaptic cleft either to adjacent neurons or into the nearby glial cells. Those neurons that produce glutamate at their Synaptics are are called glutamatergic. The principal effect of glutamate in the central nervous system is the fast excitation through direct action on ion channels...
