Members of the vitamin B complex serve as coenzymes that assist every cell in the human body. They help the body metabolize carbohydrates, proteins and fats and build DNA for new cells. Without its coenzyme, an enzyme will not function. Vitamins work together in impressive ways as coenzymes or precursors to coenzymes.
What is the function of coenzyme A in metabolism?
Coenzyme A is necessary for the metabolism of carbohydrates, amino acids, fatty acids, and other biomolecules. As a cofactor of the acyl carrier protein, pantothenic acid participates in the synthesis of fatty acids. Click to see full answer.
Which vitamin forms a part of coenzyme A?
Pantothenic acid (PA) is a B vitamin that is a component of coenzyme A (Figure 2). Coenzyme A is necessary for the metabolism of carbohydrates, amino acids, fatty acids, and other biomolecules. As a cofactor of the acyl carrier protein, pantothenic acid participates in the synthesis of fatty acids. (See OSTEOPOROSIS.)

Which of the following is a coenzyme A?
Pantothenic acid is a water-soluble vitamin B5. It is requisite to the enzyme pyruvate dehydrogenase to manufacture coenzyme-A (CoA) which is a chief substrate for Krebs cycle.
What is a component of coenzyme A?
Coenzyme A is a coenzyme containing pantothenic acid, adenosine 3-phosphate 5-pyrophosphate, and cysteamine; involved in the transfer of acyl groups, notably in transacetylations.
Is vitamin B2 a coenzyme?
Riboflavin is a water-soluble B vitamin, also known as vitamin B2. In the body, riboflavin is primarily found as an integral component of the coenzymes, flavin adenine dinucleotide (FAD) and flavin mononucleotide (FMN) (1).
Is vitamin ka a coenzyme?
Abstract. Vitamin K is a cofactor for the synthesis of blood coagulation Factors II, VII, IX and X, and inhibitors such as Protein C and S and bone matrix protein. Its active form is a coenzyme in the glutamic acid carboxylation.
Which of the following forms the part of a coenzyme?
So, the correct option is 'Vitamin B2'.
Is acetyl coenzyme A an enzyme?
They found that one of the central molecules involved in this process is a coenzyme (a molecule that helps an enzyme), which they named coenzyme A (or CoA for short). The A stood for acetyl, since one of its main jobs is to transfer two-carbon units in the form of acetyl between various biological molecules.
How is coenzyme A made?
Coenzyme A is one of five crucial coenzymes that are necessary in the reaction mechanism of the citric acid cycle. Its acetyl-coenzyme A form is the primary input in the citric acid cycle and is obtained from glycolysis, amino acid metabolism, and fatty acid beta oxidation.
What is coenzyme A derived from?
Coenzyme A is derived from adenine, ribose, and pantothenic acid (a vitamin of the B complex). The two flavin coenzymes, riboflavin mononucleotide (FMN) and flavin adenine dinucleotide (FAD), occur universally in living organisms and play important roles in biochemical oxidations and reductions.
What vitamin is part of Acetyl-CoA?
Coenzyme A (CoASH or CoA) consists of a β-mercaptoethylamine group linked to the vitamin pantothenic acid (B5) through an amide linkage and 3'-phosphorylated ADP.
Which of the following element is the component of coenzyme A and biotin?
Sulphur is one of the essential mineral elements required by the plants. Plants absorb sulphur from the soil in the form of sulphate ions (SO42−). It is required by young leaves and meristems. It is a constituent of vitamins like, thiamine and biotin, coenzyme-A (CoA) and ferredoxin.
Are all vitamin B coenzymes?
Most of the B vitamins have been recognized as coenzymes (substances that participate with enzymes in accelerating the interconversion of chemical compounds), and they all appear to be essential in facilitating the metabolic processes of all forms of animal life.
Do B vitamins act as coenzymes?
In essence, the B-complex vitamins act as coenzymes in energy metabolism. The B complex of vitamins includes thiamin (vitamin Bl), riboflavin (vitamin B2), niacin, vitamin B6 (pyridoxine), folate (folic acid), vitamin B12 (cobalamin), pantothenic acid, and biotin.
Why vitamins are considered coenzymes?
There are two types of cofactors: inorganic ions [e.g., zinc or Cu(I) ions] and organic molecules known as coenzymes. Most coenzymes are vitamins or are derived from vitamins. Vitamins are organic compounds that are essential in very small (trace) amounts for the maintenance of normal metabolism.
Is thiamine a coenzyme?
Thiamine diphosphate is a coenzyme of many enzymes, most of which occur in prokaryotes. Pyruvate dehydrogenase and 2-oxoglutarate dehydrogenase complexes as well as transketolase are the examples of thiamine-dependent enzymes present in eukaryotes, including human.
Thiamin
Thiamin, or vitamin B1, functions as a coenzyme in the oxidation of glucose. Thiamin serves as a coenzyme for several enzymes that take part in metabolic reactions. Eat meats, leafy green vegetables, whole grains and legumes to benefit from thiamin.
Biotin
Biotin works as a coenzyme for other enzymes that catalyze various chemical reactions in metabolism. For instance, biotin works with the enzyme pyruvate carboxylase, which is essential to the Kreb’s cycle, a complex series of chemical reactions that provides cells with energy. Biotin occurs in legumes, egg yolks, nuts and liver.
Cobalamin
Vitamin B12, referred to as cobalamin because it contains cobalt, serves as a coenzyme in many metabolic pathways. Vitamin B12 is synthesized by microbes and is obtained nearly exclusively from animal products.
Folic Acid
Folic acid works as a coenzyme in synthesizing several amino acids, purines and thymine, which are used in making DNA. A deficiency of folic acid results in anemia and growth failure. Folic acid is found in many foods, including dark green vegetables such as spinach, beef, eggs and whole grains. It is also synthesized by intestinal bacteria.
Riboflavin
Riboflavin, also called vitamin B2, serves as a precursor to two important coenzymes, which in turn serve as carriers of hydrogen in many important oxidation reduction, or respiration, reactions within the mitochondria of cells. Riboflavin occurs in many foods, including milk, grains and meats.
Niacin
Niacin, also called nicotinamide, serves as a precursor to two coenzymes that are hydrogen carriers in the glycolysis, Kreb’s cycle and oxidative phosphorylation metabolic processes that provide energy to the body. Niacin occurs in meats, leafy green vegetables, potatoes and peanuts.
Pyridoxine
Pyridoxine, also called vitamin B6, is a precursor to a coenzyme for important reactions that involve protein metabolism, including the synthesis of amino acids. When you eat meat, fish and poultry, you benefit from vitamin B6. It also occurs in many vegetables, such as potatoes and tomatoes.

What is the chemical that protects cells from being damaged by environmental factors?
beta-carotene. A researcher has isolated an organic, water-soluble chemical from roses. After performing in-vivo tests, the scientist determines that the chemical supplies no energy for cells, but protects cell membranes from being damaged by certain environmental factors.
What happens when a scientist mixes a small amount of a substance with living cells?
When the scientist mixes a small amount of the substance with living human cells, the chemical damages unsaturated fatty acids in the cells' plasma membranes. He is able to prevent this damage by adding vitamin E to the mixture of the chemical and cells. Based on this information, the scientist has.
