The Molecules of Life (2013) – Solutions
Manual – Kuriyan
What is the backbone of organic molecules? - answer-Carbon
What are the four major elements that make up the human body? - answer-Carbon, oxygen,
hydrogen, and nitrogen
What types of molecules are considered organic? - answer-Proteins, nucleic acids,
carbohydrates, and lipids
What is the significance of carbon's four valence electrons? - answer-They allow carbon to form
four covalent bonds, contributing to the diversity of carbon-based molecules.
What is a covalent bond? - answer-A chemical bond formed by the sharing of electrons
between atoms.
What shape does a carbon atom form when bonded with four other atoms? - answer-A
tetrahedron
What is the difference between a single bond and a double bond in carbon-containing
molecules? - answer-A single bond involves one pair of shared electrons, while a double bond
involves two pairs of shared electrons.
What are isomers? - answer-Molecules that have the same chemical formula but different
arrangements of atoms.

, What are skeletal formulas? - answer-Stick representations of carbon skeletons of organic
compounds, where carbon atoms are assumed to be bonded to hydrogen unless otherwise
noted.
What are functional groups? - answer-Specific groups of atoms within molecules that are
responsible for the characteristic chemical reactions of those molecules.
What are the seven important functional groups in the chemistry of life? - answer-Hydroxyl,
carbonyl, carboxyl, amino, sulfhydryl, phosphate, and methyl groups.
What is the role of proteins in biological systems? - answer-They provide structural support and
act as catalysts for chemical reactions.
What are nucleotides and what do they consist of? - answer-Nucleotides are the building blocks
of nucleic acids, composed of a five-carbon sugar, a nitrogenous base, and one or more
phosphate groups.
What is the structure of DNA? - answer-DNA consists of two strands of nucleotides twisted into
a double helix, with complementary base pairing (A-T, G-C).
What is the difference between monosaccharides, disaccharides, and polysaccharides? -
answer-Monosaccharides contain one sugar molecule, disaccharides contain two bonded
monosaccharides, and polysaccharides contain more than two monosaccharide monomers.
What defines lipids? - answer-Lipids are hydrophobic molecules that include fats, oils, and
steroids.
What is the difference between saturated and unsaturated fatty acids? - answer-Saturated fatty
