Document Summary
Perform most functions in your cells: protein functions, hemoglobin: transporter that carries oxygen. Immunoglobulin: defense that recognizes bacteria: myosin: motility that causes muscle contractions. Opsin: vision protein that binds retinal pigment: amino acids. There are 20 types of amino acids: condensation reaction. Two amino acids join together to form a larger molecule: chain of 4 amino acids. Longer chain constructed by further condensation reactions is called a polymer. Starch is called a homopolymer: nucleic acids, biological function. Storage of genetic information and chemical energy: structures of nucleotides in dna and rna, chain of 4 nucleotides. One of the primary functions of dna is to duplicate genetic information when a cell divides. Dna -> mrna -> protein: atp hydrolysis. Atp is the primary energy storage molecule in cells: carbohydrates, biological function. Exhibited by blood group markers of red blood cells in humans: monosaccharides- aldoses, h-c=o, monosaccharides- ketoses.
