The monomers in a polymer may be identical or different. A disulfide bond is a covalent bond between sulfur atoms in a polypeptide. Removal or addition of phosphates releases or invests energy. 2.3 carbon compound homework answers Flashcards. Functions of Carbohydrates. The nucleotide adenosine triphosphate (ATP), is composed of a ribose sugar, an adenine base, and three phosphate groups (Figure 2. 2. Review Name four groups of organic compounds found in living things. Carbon atoms also may bond with one or more functional groups such as carboxyls, hydroxyls, aminos, or phosphates.
1. b. Relate Cause and Effect What properties of carbon explain carbon's ability to form different large and complex structures? IN YOUR NOTEBOOK – COMPARE AND CONTRAST. These straight, rigid chains pack tightly together and are solid or semi-solid at room temperature (Figure 2. For instance, some carbohydrate molecules bind with proteins to produce glycoproteins, and others combine with lipids to produce glycolipids, both of which are found in the membrane that encloses the contents of body cells. Rather, carbon atoms tend to share electrons with a variety of other elements, one of which is always hydrogen. 2.3 carbon compounds answer key biology. Levels of Organization. All amino acids are identical in the amino and carboxyl groups. Any given enzyme catalyzes just one type of chemical reaction. Living organisms are made up of molecules that consist of carbon and these other elements. Saturated fats are a solid at room temperature and usually of animal origin. Lipids are made mostly from carbon and hydrogen atoms and are generally not soluble in water. If a particular essential amino acid is not available in sufficient quantities in the amino acid pool, however, synthesis of proteins containing it can slow or even cease. You are on page 1. of 3.
Three forms are important in the body: monosaccharides, disaccharides, and polysaccharides. ANALYZING DATA – COMPARING FATTY ACIDS. In the trans configuration, the carbons form a more or less linear structure; whereas, the carbons in the cis configuration make a bend (change in direction) of the carbon backbone. Steroids are lipids formed of four hydrocarbon rings. Did you find this document useful? 2.3 carbon compounds answer key of life. Maltose contains 12 atoms of carbon, but only 22 atoms of hydrogen and 11 atoms of oxygen, because a molecule of water is removed during its formation via dehydration synthesis. A disaccharide is a pair of monosaccharides. Molecules with the formulas CH3CH2COOH and C3H6O2 could be structural isomers. As was noted earlier, the basic and acidic components enable proteins to function as buffers in maintaining acid–base balance, but they also help regulate fluid–electrolyte balance. Carbon may share electrons with oxygen or nitrogen or other atoms in a particular region of an organic compound. As a group, triglycerides are a major fuel source for the body.
In contrast, globular proteins are globes or spheres that tend to be highly reactive and are hydrophilic. Single sugar molecules are also known as monosaccharides. The most common secondary structure is a spiral called an alpha-helix. A total of three water molecules are thereby released. Successive bonds between carbon atoms form hydrocarbon chains. A protein is an organic molecule composed of amino acids linked by peptide bonds. Provide examples of carbohydrates, and identify the primary functions of carbohydrates in the body. Each monomer contributes; one gives up a hydrogen atom and the other gives up a hydroxyl group. If you were to take a length of string and simply twist it into a spiral, it would not hold the shape. More ATP is produced in the presence of oxygen (O2) than in pathways that do not use oxygen. What elements does carbon bond with to make up life's molecules? Protein shape is critical to its function. Disaccharides are formed via dehydration synthesis, and the bond linking them is referred to as a glycosidic bond (glyco- = "sugar"). Section 2 3 carbon compounds. Bonds formed by dehydration synthesis between the pentose sugar of one nucleic acid monomer and the phosphate group of another form a "backbone, " from which the components' nitrogen-containing bases protrude.
Also, certain proteins act as hormones and chemical messengers that help regulate body functions. Fatty acid chains that have no double carbon bonds anywhere along their length and therefore contain the maximum number of hydrogen atoms are called saturated fatty acids. Nucleotides consist of three parts: a 5-carbon sugar, a phosphate group. Many animals store excess sugar in a polysaccharide called glycogen. Fatty acids are also components of glycolipids, which are sugar-fat compounds found in the cell membrane. Cells can also transfer a phosphate group from ATP to another organic compound. Examples of biological molecules that incorporate the benzene ring include some amino acids and cholesterol and its derivatives, including the hormones estrogen and testosterone. You can think of functional groups as tightly knit "cliques" whose members are unlikely to be parted. The data in the table illustrate how melting point decreases as the degree of unsaturation (number of double bonds) increases. If the disaccharide maltose is formed from two glucose monosaccharides, which are hexose sugars, how many atoms of carbon, hydrogen, and oxygen does maltose contain and why? RNA contains ribose, one phosphate group, and one nitrogen-containing base, but the "choices" of base for RNA are adenine, cytosine, guanine, and uracil. So far, the hydrocarbons we have discussed have been aliphatic hydrocarbons, which consist of linear chains of carbon atoms, and sometimes they can form rings with all single bonds, as shown in Figure 2. Legal Disclaimer: The information provided on is for general and educational purposes only and is not a substitute for professional advice.
Like beads in a long necklace, these monomers link by covalent bonds to form long polymers (poly- = "many"). Living things use carbohydrates as their main source of energy. The polypeptide subunits forming a quaternary structure can be identical or different. Everything you want to read.
This compound, which is commonly referred to as a fat, is formed from the synthesis of two types of molecules (Figure 2. A functional group can participate in specific chemical reactions. 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 – DESCRIBE THE STRUCTURES AND FUNCTIONS OF EACH OF THE FOUR GROUPS OF MACROMOLECULES. These may be branched or unbranched. This variety results in proteins being among the most diverse macromolecules. Proteins Function as Enzymes. Some hydrocarbons have both aliphatic and aromatic portions. Five functional groups are important in human physiology: the hydroxyl, carboxyl, amino, methyl and phosphate groups (Table 2. The remaining monosaccharides are the two pentose sugars, each of which contains five atoms of carbon. An example is enzymes, which catalyze chemical reactions. Amino acids differ from each other in a side chain called the R-group, which have a range of different properties.
ATP is the body's fundamental molecule of energy transfer. The result is a molecule with polar and nonpolar regions. Glycogen is also a polymer of glucose, but it is stored in the tissues of animals, especially in the muscles and liver. Reward Your Curiosity. Ordinary table sugar, sucrose, is a disaccharide, a compound made by joining glucose and fructose together. In this configuration, amino acids that had been very distant in the primary chain can be brought quite close via hydrogen bonds or, in proteins containing cysteine, via disulfide bonds. Hydrocarbons are organic molecules consisting entirely of carbon and hydrogen, such as methane (CH4) described above. Membranes and waterproof coverings. BUILD READING SKILLS – PHOTOGRAPHS, DIAGRAMS, AND GRAPHS.
Beta-carotene is an example of such a hydrocarbon.
