Final answer:Collagenis a protein with a triple helix structure present in the extracellular matrix of animals, not plants, and is not part of a family oflipoproteins.Explanation:Of the options given regardingcollagen, the true statement is that it has atriple helixstructure. Collagen is a structural protein found in theextracellular matrixof animal tissue, which is rich in the amino acids glycine and proline. This structure provides it with strength and elasticity, primarily in connective tissues such as tendons, cartilage, blood vessels, skin, and bone. While it is the most abundant protein in mammals, comprising about 25% of the total protein content, it is not found in plants and is not part of a family of lipoproteins. Therefore, option a) is incorrect because collagen is not a lipoprotein, option b) is incorrect because collagen has a triple, not double, helix structure, and option c) is incorrect because collagen is not present in both animals and plants. Thus, the correct answer is d) None of these, based on the given choices.Learn more aboutCollagenhere:brainly.com/question/30244632#SPJ11...
