Nonenzymatic glycosylation or glycation creates glycoproteins by the chemical addition of sugars to polypeptides. Since this type of glycosylation is nonenzymatic, the time and the concentration of sugar control glycosylation. Because people with higher circulating levels of glucose have higher levels of nonenzymatic glycosylation, measurement of the glycosylated hemoglobin A1c is a diagnostic test used to monitor blood sugar levels in persons with diabetes.
Ribose is a pentose, a simple sugar monosaccharide that has five carbon atoms per molecule. It is synthesized in the body and obtained in small amounts from consumption of ripe fruits and vegetables. Deoxyribose, a component of DNA, also is a pentose. The optimum pH for enzymes varies for different enzymes and even enzymes with similar actions may have different optimal pH based on where they act. For example, trypsin, a digestive enzyme that acts in the small intestine has an optimal pH of 8 while pepsin, which acts in the more acidic milieu of the stomach, has an optimal pH of 2.
A catabolic enzyme engages in destructive metabolism, which involves degrading or breaking down complex molecules into simpler ones with the resulting release of energy. In the body, the breakdown of food in the gastrointestinal tract by a variety of digestive enzymes is an example of a catabolic process. The opposite of catabolism is anabolism.
Anabolism is the opposite of catabolism and is a set of metabolic pathways that serve to create, construct, or synthesize larger molecules from smaller ones, such as the synthesis of carbohydrates, proteins and fatty acids. Anabolic processes consume or require energy rather than releasing energy. Examples of anabolic processes include gluconeogenesis, glyoxylate cycle, and glycosylation. Allosteric enzymes change their configurations when they bind with cofactors.
Their catalytic activity is altered — either enhanced or reduced — by binding of specific ligands at sites other than the substrate-binding site. Proteolytic enzymes, also known as proteases, catalyze the splitting or breakdown of proteins into smaller peptide fractions and amino acids. The process of accomplishing this breakdown is called proteolysis. Peptidases are a subgroup of proteases that that catalyze the hydrolysis of peptide linkages; they are present in plants and yeast and in the body.
In the body, they are involved in digestion. Amylase is the class of enzymes involved in the breakdown and digestion of starches — complex carbohydrates — into simple sugars to supply energy.
Amylases are glycoside hydrolases and act on? Plants and some bacteria make amylases. In the body, they are present in saliva and are produced by salivary glands and the pancreas. The stable three-dimensional shape and orientation of a protein its unique folds, termed its native configuration determine its function and chemical reactivity.
Proteins are composed of series of as many as twenty different L-? Proteins are distinguished by their configurations into three broad classes — globular proteins, fibrous proteins, and membrane proteins. The biosynthesis of a protein molecule uses information encoded in genes. The amino acid sequence of the protein is delineated by the nucleotide sequence of the gene that encodes the protein.
Codons, sequences of three adjacent nucleotides along a DNA or messenger RNA molecule, designate the specific amino acid to be incorporated into a polypeptide.
Biochemistry Practice Questions
Peptide bonds are the primary linkages of all proteins. They are the chemical connections that form between the carboxyl group COOH of one amino acid and the amino group NH2 of adjacent amino acids. A dipeptide contains two amino acids, a tripeptide three, a tetrapeptide four, and so on. The products of protein catabolism are used to synthesize new amino acids or are converted to other compounds via the citric acid cycle.Speak now. Biology is the study of life and all things living, while chemistry is the study of how chemicals are structure and how they interact.
