Biology 1406 Exam 1 Chapters 1-3 exam with complete solution graded A+

Disaccharide - A double sugar, consisting of two monosaccharides joined by dehydration synthesis. Glycosidic Linkage - A covalent bond formed between two monosaccharides by a dehydration reaction. Phospholipid - A lipid made up of glycerol joined to two fatty acids and a phosphate group. The hydrocarbon chains of the fatty acids act as nonpolar, hydrophobic tails, while the rest of the molecule acts as a polar, hydrophilic head. Phospholipids form bilayers that function as biological membranes. Plasmamembrane - the ___ is a lipid bilayer that includes phosopholipids and proteins to transport, receive molecules. Would be found as part of this cellular structure. Glucose + Galactose - C6H12O6. Examples of: Monosaccharides; Also: Isomers. Lactose - When these two are combined the disaccharide ____ is formed. Pyrimidines - Are a type of nitrogenous bases found in nucleic acids. One hexagon with nitrogen atoms. One Glycerol and Three Fatty Acids - Make up a: fat. Other names for a fat are: Triglycerides and Triaclyglycerols. Properties best associated with: - Fats. Stored energy, insulation. Glycogen - Storage carbohydrate; liver. Made of: many glucose moleculesPentose+ Nitrogenous base+ Phosphate= - Nucleotide Proteins - Collagen, hemoglobin, insulin, actin Polysaccharide - Ex: Chitin. Carbohydrates that are made up of more than two monosaccharides. Starch - Linkages of alpha. Iodine Test - Test used in the lap to detect presence of starch An Unsaturated Fatty Acid - It has C-C double bond in the long chain of carbons.
