Isoleucine, leucine, and lysine are three examples of amino acids that the body can not make in sufficient quantity. How are the

se compounds classified

Answer:

Leucine, isoleucine and lysine are classified as <u>essential amino acids.</u>

Explanation:

Amino acids are the important biomolecules in which an alpha-carbon is attached to a side chain R, two functional groups and one hydrogen.

The two functional groups are: amine group (-NH₂) and carboxyl group (-COOH).

There are total <u>21 amino acids in a human body</u>.<em><u> They can be divided into two types: Essential amino acids and Nonessential amino acids</u></em>

Essential amino acids are the 9 amino acids that can not be produced by the human body and thus has to be taken through diet.

<u>Example: leucine, isoleucine, lysine.</u>

<u>Therefore, leucine, isoleucine and lysine are classified as essential amino acids.</u>

Answer:

Isoleucine, leucine and lysine are essential amino acids.

Explanation:

The amino acids are classified based on different criteria like

a) Polarity

b) acidc, basic or neutral behavior

c) aromatic or non aromatic

One important classification is that amino acids can be "essential" or "non essential".

Essential amino acids are those which cannot be made by our body and thus are required in our diet.

Non essential amino acids are those which our body can synthesize. So are not required in our diet.

So  Isoleucine, leucine and lysine are essential amino acids.

Find the empirical formula of the compound ribose, a simple sugar often used as a nutritional supplement. A 14.229 g sample of r
MakcuM [25]

Answer:

CH2O

Explanation:

Firstly, we need to convert the masses of the elements to percentage compositions. This can be done by placing the mass of each element over the total mass multiplied by 100% . We can start with carbon.

C = 5.692/14.229 * 100 = 40%

O = 7.582/14.229 * 100 = 53.29%

H = 0.955/14.229 * 100 = 6.71%

We then proceed to divide each percentage composition by their atomic mass of 12, 16 and 1 respectively.

C = 40/12 = 3.333

O = 53.29/16 = 3.33

H = 6.71/2 = 6.71

Dividing by the smaller value which is 3.33

C = 3.33/3.33 = 1

O = 3.33/3.33= 1

H = 6.71/3.33 = 2

The empirical formula of the compound ribose is CH2O

Explain surface tension and capillary action
Andreas93 [3]

Adhesion of water to the surface of a material will cause an upward force on the liquid. The surface tension acts to hold the surface intact. Capillary action occurs when the adhesion to the surface material is stronger than the cohesive forces between the water molecules.

Which of the following abilities is NOT a physical property of matter?
Morgarella [4.7K]

Answer:

Ability to react chemically with other substances is not a physical property.

Explanation:

The ability to dissolve in other substance can be both physical and chemical property.

It depend upon the type of solute, solvent and reaction between them.

For example, if NaCl is dissolved in water it gives sodium and chloride ions which are behaving different from the original compound. it will be chemical change but if water is evaporated it will give back sodium chloride and than it will be a physical change.

But if dissolved substances make the mixture not compound it will than a physical change, and solubility will consider a physical property.

Physical properties:

The properties which are not associated with change in chemical composition are called physical properties.                                                                                          

Example

Density, color, hardness, conductance, melting point, boiling points all  are physical properties.

Chemical properties:

The properties which are associated with change in chemical composition are called chemical properties.        

Example:

Toxicity, flammability, heat of combustion etc.

Combustion of fuel or wood: that oil or wood convert into energy, CO2 and ash in case of wood

The reaction of Hydrogen and oxygen:

H 2 (g)  + O 2  (g) -------------------------------------> 2H 2O  (l)
