Amino acids are the primary units of a protein. In total of 21 types of these organic compounds. Each amino acid has its own properties. Amino acids are largely grouped as essential and non-essential. The essential amino acids are ones which are not synthesized by the body and are essential to intake in the diet as they play important roles in the body, while the non-essential ones are made by the body.

Summary Introduction

Introduction:

Amino acids are the primary units of a protein. In total of 21 types of these organic compounds. Each amino acid has its own properties. Amino acids are largely grouped as essential and non-essential. The essential amino acids are ones which are not synthesized by the body and are essential to intake in the diet as they play important roles in the body, while the non-essential ones are made by the body.

Expert Solution & Answer

Answer to Problem 1TYK

Correct answer:

All amino acids contain a carboxylic and an amino group.

Explanation of Solution

Justification/ Explanation for the correct answer:

Option (d) is given that every amino acid consists of a carboxylic and an amino group. The amino acids string in a polypeptide by forming a peptide bond sandwiched in the NH2 of one amino acid and the carboxylic group of the other. The amine group differ only in their alkyl group, which also determines its solubility and reactivity. Hence, option (d) is correct.

Explanation for the incorrect answer:

Option (a) is given that an amino acid has a carboxyl and a carbonyl group. This is a wrong statement as amino acid does not have a carbonyl group. It has an alkyl group, which is different for different amino acids. This alkyl group could contain a carbonyl bond, but it is not true for every amino acid. So, it is an incorrect option.

Option (b) is given that every amino acid has a carbonyl group and an N-H group. This is a wrong statement as every amino acid has an NH₃⁺ group and carboxyl group (COOH) when present single. After bonding, with another amino acid, one hydrogen molecule of the NH₃⁺ group and OH group of the COOH group forms a water molecule. A bonded amino acid has NH₂ group a carbonyl group. So, it is an incorrect option.

Option (c) is given that each amino acid has a hydroxyl group and an amino group. This is a wrong statement as every amino acid has a carboxyl group and an amino group. The other bond is with an atom of hydrogen and an alkyl group. The alkyl group may contain a hydroxyl group (OH), but it is not true for every amino acid. So, it is an incorrect option.

Hence, options (a), (b), and (c) are incorrect.

Conclusion

Thus, it can be concluded that each amino acid has a carboxyl group and an amino group along with a hydrogen atom. The fourth bond is with an alkyl group, which is different for every amino acid.

*Example 2: Tracing the path of an autosomal dominant trait Trait: Neurofibromatosis Forms of the trait: The dominant form is neurofibromatosis, caused by the production of an abnormal form of the protein neurofibromin. Affected individuals show spots of abnormal skin pigmentation and non-cancerous tumors that can interfere with the nervous system and cause blindness. Some tumors can convert to a cancerous form. i The recessive form is a normal protein - in other words, no neurofibromatosis.moovi A typical pedigree for a family that carries neurofibromatosis is shown below.
