Is fructose gives positive test with tollens reagent?
Fructose does not give a positive test with Tollens' reagent because it is a reducing sugar that does not have a free aldehyde group capable of reducing the Tollens' reagent. Tollens' reagent is typically used to detect the presence of aldehydes but may not react with fructose due to its ketone functional group.
Why is lactic acid not a fatty acid?
Lactic acid is a byproduct of anaerobic metabolism in muscles, while fatty acids are a type of lipid that serve as a major energy source. They are chemically distinct molecules with different structures and functions in the body.
What classes of enzyme does synthase belong to?
Synthase enzymes belong to the class of enzymes known as lyases. Lyases are enzymes that catalyze the breaking of various chemical bonds in the absence of water. Synthases specifically are involved in the synthesis of new molecules by joining two molecules together.
That simply means this:
That the enzymes natural reaction to the concentration of the of the substrate (based on its chemical makeup) will react at .4 slygometers. This is based on the Scale of Enzyme dependency on the substrates, again "natural" reaction to the enzymes reaction on itself. Never let it fool you that 1/8th of a slygometer is equivalent to a Decominuter on the Enzyme Friction Scale. This is a common misconception and more so just a blatant misunderstanding of the rudimentary basis of the scale itself.
For those of you who don't know the scale conversions they are as follow:
Slygometer Ct. Decominuter Value
.4 .114
.8 .228 * and so on.
Also please wear gloves when marrying any of these chemicals if the Decominuter reads above .14. The reason is, is that the chemical begins to decompose and speed up the half life of itself based on the Degeneration theory, this can cause a devastatingly harsh burn on your knuckle or finger pad. Believe me it hurts bad, there is a procedure to stop the burn from sinking to the bone called Micro-Magnesis, highly expensive if your lucky enough to bump into the doctor who holds qualification to do so.
Is hydrogen bond a biologically weak bond?
Biologically, hydrogen bonds are considered to be strong intermolecular forces.
What are the product and the reacants for cellular respiration?
Reactants are glucose and oxygen.Products are ATP and CO2.
What happens when objects are placed into liquid hydrogen?
When objects are placed into liquid hydrogen, they become extremely cold due to the low temperature of liquid hydrogen (-252.87°C). Depending on the material, they may become brittle and susceptible to breaking. Some materials may also experience changes in electrical conductivity or magnetic properties when exposed to such extreme cold.
Can fatty acids be converted to oxaloacetate?
Not directly. Fatty acid β-oxidation results in acetyl CoA, which is then entered to the Citric Acid cycle. The "last" step of the cycle is the formation of oxaloacetate from malate.
What are the three elements that are typically found in carbohydrates?
Carbohydrates are made of carbon, hydrogen and oxygen.
How are substrates like keys and enzymes like locks a bad analogy?
Well, it is just a representation, substrates are normally smaller molecules, and enzymes are in huge size hence they used this analogy!
What are lipids of large molecules?
Lipids are fats, or to be technical, they are non-polar organic molecules. They do form large molecules but they do not polymerize.
What is the saponification value in an experiment?
determination of saponification value (or "saponification number", also referred to as "sap" in short) represents the number of milligrams of potassium hydroxide or sodium hydroxide required to saponify 1g of fat under the conditions specified. It is a measure of the average molecular weight (or chain length) of all the fatty acids present. As most of the mass of a fat/triester is in the 3 fatty acids, it allows for comparison of the average fatty acid chain length. If more moles of base are required to saponify N grams of fat then there are more moles of the fat the chain lengths are relatively small, given the following relation: Number of moles = mass of oil/relative atomic mass Handmade soap makers who aim for bar soap use NaOH sap values which are derived from the saponification value calculated by laboratories (KOH sap value). To convert KOH values to NaOH values, divide the KOH values by the ratio of the molecular weights of KOH and NaOH (1.403). Standard methods for analysis are for example: ASTM D 94 (for petroleum) and DIN 51559. The calculated saponification value is not applicable to fats and oils containing high amounts of unsaponifiable material, free fatty acids (>0.1%), or mono- and diacylglycerols (>0.1%).
What pigments do Nannocloropsis oculata utilize to photosynthesize?
These algae utilize chlorophyll a in photosynthesis. There is a big difference between the species of this genus with other microalgae. Nannocloropsis algae have neither chlorophyll b nor chlorophyll c.
What are some side effects of salicylic acid as a pain reliever?
Several effects are:
- gastrointestinal bleeding in cases of abuse
- disagreeable for rare allergic individuals
- interaction with some other drugs or diseases
The use of sterols and phospholipids?
Phospholipids are what allow our body to utilize water and fat. they can also act as carriers in the blood. Phospholipids are found in the cell walls. Sterols: are types of fat that consit of many compound within the body such as bile, sex homonoes, vitamines D and cortisols. They are not used for energy both phospholipids and Sterols are two of the remaining thre categories of lipids
How did DNA help classify the platypus?
DNA help classify the platypus because with out it the DNA the platypus would be classified with the marsupials which would be wrong.
How would DNA extraction differ in a bacterial Cell?
The glyco-callyx (sugar-protein) covering of the eukaryotic Cell Coat has much less strength than the mostly cellulose (comprised of strongly bound - bacterially released - glucose) based Cell Wall of the prokaryotic bacteria.
Dna extraction is more difficult in prokaryotes due to the tough Cell Wall.
Which pyrimidine base provides additional stability to DNA over RNA?
I would assume you need thymine as the answer here.
What happens to the zygote that is monosomic?
A monosomic zygote has one less chromosome than normal. This can result in genetic disorders or developmental abnormalities. Most monosomic zygotes are not viable and typically result in miscarriage.
Which form of fatty acids occur in humans most commonly?
In humans, the most common form of fatty acids are long-chain fatty acids, which typically have between 14 to 22 carbons in their structure. These fatty acids are predominantly found in diets and make up the majority of the fats in our bodies, serving as a key source of energy and playing various essential roles in metabolism.
