The 20 different amino acids found in polypeptides exhibit different chemical and physical properties because of different?
Amino acids exhibit different chemical and physical properties because of their R groups.
An amino acid is asymmetric, meaning that it is a carbon bound to 4 different elements.
Three out of the four are the same in every amino acid.
These three are: an amino group, a Hydrogen, and a carboxyl group (otherwise known as an acid). Hence the name Amino Acid.
The 4th grouping is called the R group, and it is different for every amino acid.
This R group determines the shape of the amino acids and the shape determines function.
What else can I help you with?
Pure substances that have properties entirely different from the atoms that make it up are?
compounds. Compounds are formed when atoms of different elements chemically bond together to create a new substance with unique properties that are different from the properties of the individual atoms. An example of a compound is water (H2O), which has different physical and chemical properties compared to its constituent elements, hydrogen and oxygen.
When carbon dioxide in air converts to more complex molecules by plants during photosynthesis is that a physical change?
No, the process of carbon dioxide being converted into more complex molecules by plants during photosynthesis is a chemical change, not a physical change. Chemical changes involve the formation of new substances with different chemical properties, whereas physical changes only affect the physical state of a substance without altering its chemical composition.
Properties of isomers?
Isomers are molecules with the same molecular formula but different structural arrangements or spatial orientations. They have distinct physical and chemical properties due to their unique structures, such as boiling points, melting points, and reactivity. Isomers can exhibit different biological activities, environmental behaviors, and industrial applications.
Is color and hardness examples of chemical properties?
This is False. The colour has to change to be a chemical change/property. If it stays the same, it is physical. Hardness is an example of a physical property. (ex. If I melt a piece of hard steel, it will become soft, liquid probably, but it isn't hard anymore, this change is reversible, therefore a physical change/property)
What is differential stain?
A differential stain is a type of staining technique used in microbiology to differentiate between different types of bacteria or cellular structures based on their physical and chemical properties. Examples of differential stains include the Gram stain and acid-fast stain.
Does chemical and physical properties are probably the same?
No. Chemical and physical properties are different.
When do the physical and chemical properties change?
Physical and chemical properties change as the result of a chemical change, which produces new products with different physical and chemical properties than the reactants.
How are chemical properties and physical properties of matter different?
its different because physical it bruoght on by us and chemical is different particles from once was a different substance.
What happens to the chemical and physical properties of a substance formed in a chemical reaction?
The chemical properties of a substance change during a chemical reaction, meaning the substance undergoes a chemical change and forms new substances with different properties. The physical properties may also change, such as color, texture, or state of matter.
What action will result in product with chemical properties?
A chemical reaction will result in a product with not only chemical properties (which are different than the reactants), but also physical properties (which are also different from the reactants).
Why chemical compound does not maintain the same properties as its parent elements?
Because reactants and products have different chemical compositions and consequently different chemical and physical properties.
What makes salts different?
Each salt has a different chemical composition and consequently different chemical and physical properties.
Does a chemical reaction change physical properties or chemical?
A chemical reaction changes the chemical properties of substances involved by forming new substances with different chemical compositions. This can result in changes in physical properties such as color, temperature, odor, and state of matter.
Why don't compounds have the same chemical properties that form them?
Because an element is an element and a molecule is a molecule; they are different chemical entities and of course they have different chemical and physical properties.
Different between physical and chemical change?
In a physical change the object changes appearance but in a chemical change the object turns into something different with different properties.
Is isotopes of same element have same properties?
The differences in chemical properties are not significant (excepting protium and deuterium); the physical properties are different.
What statement can be made when compairing the chemical and physical properties between a compound and the elements from which it is formed?
The chemical and physical properties of a compound are different than those of the elements from which it is formed.
