What else can I help you with?
What are some of the limitation of the Benedict's test on sugars?
The limitations are it doesn't react with all small sugars. The test does not allow for you to determine which sample sugar is present. The test is qualitative which allow you to only detect the presence of a certain molecule.
Do sugars ionize to an appreciable extent when dissolved in water?
No, sugars do not ionize to an appreciable extent when dissolved in water. Sugars are covalent compounds that do not dissociate into ions in solution.
Why dont polysaccharides give a positive test with Fehling's solution?
Fehling test is only suitable for reducing sugars, that means, monosaccharides in its open form with an aldehyd available. Polysacchardes have the aldehydes in a acetal form and they can not react
Why l forms of sugar are not found in nature?
L-sugars are not found in nature because most organisms synthesize D-sugars, which have a different configuration at the chiral carbon. This is due to the enzymatic processes that occur in living organisms which specifically produce D-sugars. Consequently, L-sugars are not common in nature and are not widely utilized by living organisms.
What is the only positive ion present in the solution when HCL is dissolved in water?
since HCL has 2 ions: H+ and Cl- i think the only positive ion present would be H+: that would make sense, but im not positive on that
Do sugars have nitrogen?
No. Sugars are composed of carbon, hydrogen, and oxygen, but not nitrogen.
Why use only D sugars are biologically important?
. whyOnly D sugars are biologically important?
Would glucose solution produce a positive Benedicts test?
No, Benedicts reagent will show positive results if the carbohydrate is a reducing sugar. You will know if it is positive if the sample will turn from blue to green then to orange when you are cooling the solution, which is the last step when you are performing the benedicts test for carbohydrates.
Are amino acids the building block of sugar?
No, amino acids are the building blocks of proteins, not sugar. Sugars are made up of carbon, hydrogen, and oxygen atoms, and are a type of carbohydrate. Both amino acids and sugars are essential components of biological molecules and play important roles in the body.
What are some of the limitation of the Benedict's test on sugars?
The limitations are it doesn't react with all small sugars. The test does not allow for you to determine which sample sugar is present. The test is qualitative which allow you to only detect the presence of a certain molecule.
Are proteins bonded together resulting in simple sugars?
No. Sugars are carbohydrates.
Do enzymes break down into simple sugars?
No, protein is broken down into amino acids. Simple sugars are only formed when carbohydrates are digested.
Why is Benedict's test unreliable?
Benedict's test is considered unreliable because it can give false positive or false negative results. It may not accurately differentiate between reducing sugars and other substances that can also react with the Benedict's reagent, leading to inaccurate conclusions about the presence of sugars in a sample. Additionally, the test may not detect certain types of sugars or may give inconsistent results depending on factors such as temperature and pH.
Can the absolute value be positive or negative?
Only positive.
Is a negative plus a positive a positive?
If, and only if the positive value is > the negative value.
Why does a positive minus a positive equal a positive?
It is NOT necessarily a positive. It will be positive only if it is a larger number minus a smaller number.
Are natural sugars harmful sugars?
Generally Not. Only sugar naturally in fruits should be eaten. Overconsumption of sugar can cause many diseases. Further it is empty calories. Meaning that when you eat foods sweetened with extra sugar like candy, you are consuming calories with little if any nutritional value. Also sugar is bad for your teeth.
