Which feature of large biological molecules explains their great diversity?
Which feature of large biological molecules explains their great diversity?
The correct answer is (C)The many ways that monomers of each class of biological molecule can be combined into polymers. Large biological molecules are polymers, consisting of many subunits linked to form a long chain.
What functional group makes lemons sour?
Citrus fruits such as oranges and lemons contain citric acid. Figure 25.12. 2: Citric acid is a large carboxylic acid with three ionizable hydrogen atoms. It is found in citrus fruits and gives them their sour or tart flavor.
Which functional group causes citric acid?
Some compounds contain multiple carboxylic acids within a single molecule. For example, citric acid (three carboxyl groups) is especially abundant in citrus fruits and it used as a flavoring and preservative in many foods and beverages.
What are molecules that have the same chemical formula but different three dimensional shapes?
Molecules that have the same chemical formula (same numbers of each atom) but different three-dimensional shapes are called Stereoisomers. Explanation: Stereoisomerism is a phenomenon in which molecules have same molecular formula but have different arrangement of atoms or group of atoms in space.
What are the four main categories of large biological molecules present in living systems?
Biomolecule, also called biological molecule, any of numerous substances that are produced by cells and living organisms. Biomolecules have a wide range of sizes and structures and perform a vast array of functions. The four major types of biomolecules are carbohydrates, lipids, nucleic acids, and proteins.
Which two functional groups are always found in amino acids?
Carboxyl and amino groups are always found in amino acids. The amino group consists of an atom of nitrogen bound to hydrogen atoms by single bonds. An organic compound is considered an amine that contains an amino group.
What are the major functional groups in organic molecules?
Each type of organic molecule has its own specific type of functional group. Functional groups in biological molecules play an important role in the formation of molecules like DNA, proteins, carbohydrates, and lipids. Functional groups include: hydroxyl, methyl, carbonyl, carboxyl, amino, phosphate, and sulfhydryl.
What is the other name of citric acid?

What’s the pH of citric acid?
between 3 and 6
Citric acid is naturally concentrated in a variety of fruits and vegetables and is particularly concentrated in lemons and limes. As with most organic acids, citric acid is a weak acid, with a pH level between 3 and 6.
How do you identify an isomer?
You can tell them apart by their bonding patterns and how they take up three-dimensional space. Identify structural (constitutional) isomers by their bonding patterns. The atoms of the compounds are the same but they are connected in such a way as to make different functional groups.
Why are so many different shapes of molecules possible?
The large diversity of shapes of biological molecules is possible because of the extensive presence of ____ in the molecules. (Concept 4.2) Which of the following is a hydrocarbon?
How are complex organic substances formed in living organisms?
E) complex organic substances are the result of a series of sequential synthetic reactions occurring in both living organisms and nonliving systems. Vitalism gave way to mechanism, the view that _____.
Which is true about most organic compounds contain carbon?
Now up your study game with Learn mode. Most organic compounds contain carbon and _____. (Concept 4.1) The experiments of Wöhler, Kolbe, Miller, and other chemists invalidated the concept of vitalism by demonstrating that _____. Concept 4.1)

How many functional groups are there in a molecule?
The molecule shown here contains four functional groups (−OH−OH, −SH−SH, −NH2−NH2, and −OPO2−3−OPO32−) attached to a carbon chain that is six carbon atoms long. Functional groups confer specific chemical properties to the molecules of which they are a part.
