___contain both nucleic acid and protein. Section B 判断题: The ‘acidic’ amino acids have additional carboxyl groups which are usually negatively charged. 填空题: Amino acids are linked by___between α-carboxyl andα-amino groups. The resulting polypeptide sequence has an___...
Amino acid - Reactions, Structure, Synthesis: Amino acids via their various chemical functionalities (carboxyls, amino, and R groups) can undergo numerous chemical reactions. However, two reactions (peptide bond and cysteine oxidation) are of particular
Amino acid - Building Blocks, Structure, Functions: One of the most useful manners by which to classify the standard (or common) amino acids is based on the polarity (that is, the distribution of electric charge) of the R group (e.g., side chain). Grou
Well,amino acidsin food make up protein. When protein is digested it is once again broken down into specific amino acids, that are then selectively put together for different uses. These new proteins formed in the body are what make up most solid matter in the body: skin, eyes, heart, i...
Glycerol can be used to ___. (a) provide energy to cells (b) synthesize glucose (c) synthesize fats (d) More than one choice is correct. Organic polymers of amino acids linked together by peptide bonds are called: A. proteins. B. codons. C. ...
While several amino acid types may bind to a tRNA, only one amino acid at a time may bind. Amino acids are attached to tRNA at the acceptor stem by the enzyme aminoacyl–tRNA synthetase in two steps. This enzyme catalyzes the hydrolysis of ATP, covalently bonding an amino acid to AMP, ...
while amino acids such as serine, threonine, and cysteine are polar and have hydrophilic side chains. The side chains of lysine and arginine are positively charged, and therefore these amino acids are also known as basic amino acids. Proline has an R group that is linked to the amino group...
Amino acids are made up of what compounds? Fill in the blank: Polymers of amino acids that are linked in linear chains and that contain atoms of nitrogen are called. Describe what might happen to an amino group or a carboxyl group of an amino ...
Synonymous codons translate into chemically identical amino acids. Once considered inconsequential to the formation of the protein product, there is evidence to suggest that codon usage affects co-translational protein folding and the final structure of
18 of the 20 amino acids were considered because during quantitation, amino acids which largely exist in protein-bound forms, require hydrolysis into free amino acids during which amino groups from glutamine and asparagine are also hydrolyzed to make glutamic and aspartic acid. Thus, the abundance ...
