(1)推理判断题。根据第一段A protein is a large,complex macromolecule composed of one or more long chains of amino acids (氨基酸).Present in and vital to every living cell,proteins are essential for the structure,function,and regulation of the body
Proteins, which are composed of amino acids, help transport lipids in the bloodstream. These proteins need to be able to cluster with other nonpolar molecules and exclude water. Which of the following would best describe the side chains of these amino acids in the lipid transport proteins? A....
all being composed of three intertwined polypeptide chains. In some collagens the chains are linked together bycovalent bonds, yielding a ropelike structure of greattensile strength. Indeed, the toughness ofleather, chemically treatedanimalskin, is due to its content of collagen. Elastin is also a...
(R) group for side chains that differ from each amino acid. Proteins are constitutional material of the human body and are the most abundant intracellularmacromolecules. According to their composition, proteins are classified into simple andcomplex proteins. Simple proteins are composed exclusively of ...
Signaling pathways allow cells to detect and respond to a wide variety of chemical (e.g. Ca2+ or chemokine proteins) and physical stimuli (e.g., sheer stress, light). Together, these pathways form an extensive communication network that regulates basic c
Nanostructures built from biomolecules such as proteins, DNA and RNA are attracting attention in many areas of biological and materials sciences. Such nanoscale engineering was pioneered with proteins, yet the use of DNA is rapidly gaining traction. What
(B) Two orientations of the three-dimensional structure of Sac7d (pdb code 1AZP) representing identical residues among the thirteen proteins (green), those which are not conserved (red) and Thr17 (blue). The side chains of residues which are involved in DNA interaction are depicted as ...
B. mori silk has a core–shell type structure, with its core composed of a complex of 3 proteinaceous components: a large protein, known as heavy chain fibroin (H-chain, ca. 350 kDa) that is linked to a second small protein, known as light chain fibroin (L-chain, ca. 25 kDa) via...
domains in Aa43-1 showing conservation of 60% residues with shared chemistry, (c) primary structure of four GSrCPs with repeated domains of high homology to AaCP19 (d) Multiple sequence alignment of all 19-homologous domains, where conserved regions are composed mainly of low complexity residues...
