Which of the following molecules is not one of the major biomacromolecules? A. Nucleic Acid B. Protein C. Amino Acid D. Carbohydrate

Respuesta :

Answer: C

Explanation: Amino acids are not one of the four biomacromolecules. The biomacromolecules are nucleic acids, protiens, carbohydrates, and lipids.

Amino Acid is not one of the major biomacromolecules. Amino acids are the micro molecules that join to form proteins by peptide bonds.

What are Biomacromolecules?

Biomacromolecules are the kind of biomolecules. Biomolecules are the substances made inside the cells of the living body.

Biomolecules are further classified into Biomacromolecules and Bio micro molecules.

Biomacromolecules are  biomolecules having a size of 800 to one thousand Daltons, high molecular weights and complex structures. They are biological polymers of various simple or monomeric units.

Biomacromolecules includes the primary metabolites and secondary metabolites. Macromolecules are acid soluble and their molecular weights range from 18 to 800 Da.

Macromolecules are biomolecules that are characterized by their acid insoluble property.

Lipids are an exception because despite having molecular weight of less than 800 Da, they are classified as biomacromolecules owing to their acid insoluble property. Hence, lipids don't seem to be strictly macromolecules.

Example of biomacromolecules are: Proteins, Carbohydrates, Lipids.

Proteins:

They represent the bulk of biomolecules in a cell.

They are fashioned of simpler units known as amino acids that are linked together by covalent bonds known as peptide bonds. There are twenty one different types of amino acids.

Proteins are responsible for several functions within the body and thus they are classified into different types based on their function e.g.  structural proteins, enzyme proteins, transport proteins etc.

Proteins have a complex structure that divides into the Primary structure, Secondary structure and tertiary structure.

Carbohydrates:

Carbohydrates are biomolecules that primarily contain carbon, hydrogen and oxygen conjointly referred to as as sugars.

Carbohydrates are classified into totally different classes reckoning on the number of monomer units present in them such as monosaccharides(single monomer unit), disaccharides( two monomer units), polysaccharides(multiple monomer units).

Monosaccharides produce other names e.g. glucose, fructose

Monosaccharides have other names e.g. glucose, fructose.

Glucose is the energy currency of the cells in animals and fructose is in plants. These sugars contain an aldehyde group or a keto group and the bond between these groups and an alcoholic group of another monomer unit is known as a glycoside bond or linkage.  

Polysaccharides are primarily of two types: structural and food storage

What are amino acid:

Amino acids are organic compounds that contain amino carboxylic acid  functional groups, along with a side chain (R group) specific to each amino acid.

Amino Acid was discovered in 1806 by Louis-Nicolas Vauquelin and Pierre Jean Robiquet who isolated a compound from asparagus that was afterward named asparagine, the first amino acid.

Uses of Amino Acid:

- In industrial area

- Use in expanding Genetic Code

- Usage in biodegradable plastics

- As chemical Building blocks

Amino acid is a monomer that creates proteins.

Amino acids are organic molecules containing an amino group, a hydroxyl group, and a carbon side chain.

All amino acids share the same basic structure. However, they differ in their carbon side chain.

Amino acids are either non-essential or essential where non-essential amino acids are synthesized inside the human body from glucose mainly so it is not essential to get them from the diet.

Whereas essential amino acids don't seem to be synthesized within the body so that they should be obtained from the diet.
