Concept explainers
(a)
Interpretation:
The validation of the given statement that carbohydrates are the most abundant class of bioorganic molecules on earth has to be stated.
Concept introduction:
Those substances that do not contain carbon are known as bioinorganic substances and those substances that contain carbon are called bioorganic substances. Carbohydrates are one of the essential macronutrient in our diet. Carbohydrates is the major source of energy and is important for balanced diet.
(b)
Interpretation:
The validation of the given statement that dietary intake of plant materials is the major carbohydrate source for humans and animals has to be stated.
Concept introduction:
Carbohydrates are one of the essential macronutrient in our diet. They are usually present in bread, pasta, potato, basically the starchy foods. Carbohydrates is the major source of energy and is important for balanced diet.
(c)
Interpretation:
The validation of the given statement that the plants use carbohydrates for structural elements but not as a source of energy has to be stated.
Concept introduction:
Carbohydrates are one of the essential macronutrient in our diet. They are usually present in bread, pasta, potato, basically the starchy foods. Carbohydrates is the major source of energy and is important for balanced diet.
(d)
Interpretation:
The validation of the given statement that part of the structural framework of DNA and RNA molecules involves carbohydrates has to be stated.
Concept introduction:
Carbohydrates are one of the essential macronutrient in our diet. They are usually present in bread, pasta, potato, basically the starchy foods. Carbohydrates is the major source of energy and is important for a balanced diet.

- Nonearrow_forwardNonearrow_forwardIn the solid state, oxalic acid occurs as a dihydrate with the formula H2C2O4 C+2H2O. Use this formula to calculate the formula weight of oxalic acid. Use the calculated formula weight and the number of moles (0.00504mol) of oxalic acid in each titrated unknown sample recorded in Table 6.4 to calculate the number of grams of pure oxalic acid dihydrate contained in each titrated unknown sample.arrow_forward
- 1. Consider a pair of elements with 2p and 4p valence orbitals (e.g., N and Se). Draw their (2p and 4p AO's) radial probability plots, and sketch their angular profiles. Then, consider these orbitals from the two atoms forming a homonuclear л-bond. Which element would have a stronger bond, and why? (4 points)arrow_forwardWrite the reaction and show the mechanism of the reaction. Include the mechanism for formation of the NO2+ 2. Explain, using resonance structures, why the meta isomer is formed. Draw possible resonance structures for ortho, meta and para.arrow_forwardNonearrow_forward
- 3. A molecular form of "dicarbon", C2, can be generated in gas phase. Its bond dissociation energy has been determined at 599 kJ/mol. Use molecular orbital theory to explain why energy of dissociation for C₂+ is 513 kJ/mol, and that for C2² is 818 kJ/mol.
