Although both plants and animals synthesize sterols, the type that makes the most important contribution to human structure and function is cholesterol, which is synthesized by the liver in humans and animals and is also present in most animal-based foods. More ATP is produced in the presence of oxygen (O2) than in pathways that do not use oxygen. Some hydrocarbons have both aliphatic and aromatic portions.
Molecules with the formulas CH3CH2COOH and C3H6O2 could be structural isomers. What elements does carbon bond with to make up life's molecules? If each carbon atom in a lipid's fatty acid chains is joined to another carbon atom by a single bond, the lipid is said to be saturated. Before exploring these compounds, you need to first understand the chemistry of carbon. Critical Thinking Questions. The nucleic acids differ in their type of pentose sugar. Carbon-carbon bonds can be single, double, or triple covalent bonds. A disaccharide is a pair of monosaccharides. While carbohydrates and lipids are composed of hydrocarbons and oxygen, all proteins also contain nitrogen (N), and many contain sulfur (S), in addition to carbon, hydrogen, and oxygen. Discuss lipids important in human functioning. A steroid compound (referred to as a sterol) has as its foundation a set of four hydrocarbon rings bonded to a variety of other atoms and molecules (see Figure 2. 2.3 carbon compounds answer key lime. The names of all three molecules start with the prefix "eth-, " which is the prefix for two carbon hydrocarbons. Denatured proteins lose their functional shape and are no longer able to carry out their jobs.
In fact, the chemical formula for a "generic" molecule of carbohydrate is (CH2O) n. Carbohydrates are referred to as saccharides, a word meaning "sugars. " Carbon atoms can also bond to each other, which gives carbon the ability to form millions of different large and complex structures. 2.3 carbon compound homework answers Flashcards. Removal or addition of phosphates releases or invests energy. Carbon atoms do not complete their valence shells by donating or accepting four electrons. The bonds between their monomers are broken, via the donation of a molecule of water, which contributes a hydrogen atom to one monomer and a hydroxyl group to the other.
Hydrogen bonds between functional groups (within the same molecule or between different molecules) are important to the function of many macromolecules and help them to fold properly into and maintain the appropriate shape for functioning. The body can use proteins for energy when carbohydrate and fat intake is inadequate, and stores of glycogen and adipose tissue become depleted. Interactive Link Questions. Carbon and its compounds 2 mark questions. Monomers form polymers by engaging in dehydration synthesis (see Figure 2.
Cells can also transfer a phosphate group from ATP to another organic compound. Proteins are critical components of all body tissues. Methane, an excellent fuel, is the simplest hydrocarbon molecule, with a central carbon atom bonded to four different hydrogen atoms, as Figure 2. Lipids are hydrophobic compounds that provide body fuel and are important components of many biological compounds. Single sugar molecules are also known as monosaccharides. For this reason, we describe methane as having tetrahedral geometry. The generation consisted of wild-type males and wild-type females. Amino acids join via dehydration synthesis to form protein polymers (Figure 2. You are on page 1. of 3. RNA contains the sugar ribose and DNA contains the sugar deoxyribose.
As you can tell from their common names, you consume these in your diet, however, your body cannot use them directly. Whereas a diet high in saturated fatty acids increases the risk of heart disease, a diet high in unsaturated fatty acids is thought to reduce the risk. Hydro-lysis reaction. This contributes to the hydrophilic nature of whatever molecule on which it is found. This carboxyl group ionizes to release hydrogen ions (H+) from the COOH group resulting in the negatively charged COO- group. Many steroids, such as hormones, serve as chemical messengers. This hydrolysis reaction can be written: ATP + H2O → ADP + Pi + energy. Moreover, nerve cells (neurons) in the brain, spinal cord, and through the peripheral nervous system, as well as red blood cells, can only use glucose for fuel. PDF, TXT or read online from Scribd. A carbohydrate is a molecule composed of carbon, hydrogen, and oxygen; in most carbohydrates, hydrogen and oxygen are found in the same two-to-one relative proportions they have in water.
When they share, however, they do not share all their electrons exclusively with each other. A protein's primary structure is the sequence of its amino acids. A functional group is a group of atoms linked by strong covalent bonds and tend to function in chemical reactions as a single unit. The breakdown of sugars, such as glucose, supplies immediate energy for cell activities. A peptide, in fact, is a very short chain of amino acids. DNA and RNA are nucleic acids that function in protein synthesis. The few oxygen atoms they contain are often at the periphery of the molecule. These geometries have a significant impact on the shape a particular molecule can assume. This group can vary in size and can be polar or nonpolar, giving each amino acid its unique characteristics. Which of the following statements is false?
The large macromolecules formed from monosaccharides are known as polysaccharides. For example, the protein shown, hemoglobin, consists of four subunits. Butter and lard are examples, as is the fat found on a steak or in your own body. Cholesterol is an important component of bile acids and compounds that help emulsify dietary fats. Lipids are a large and varied group of biological molecules. Proteins are polymers made up of nitrogen-containing monomers called amino acids.
