WHAT ARE; L-Carnitine and Taurine?

Answer 1

2 supplements/amino acids that some people use for energy, working out, etc - All supplements have side effects and should be researched before using. :o)

What is it?
Taurine is an amino acid-like compound and a component of bile acids, which are used to help absorb fats and fat-soluble vitamins. Taurine also helps regulate the heart beat, maintain cell membrane stability, and prevent brain cell over-activity


What is it?
L-carnitine is made in the body from the amino acids lysine and methionine, and is needed to release energy from fat. It transports fatty acids into mitochondria, the powerhouses of cells. In infancy, and in situations of high energy needs, such as pregnancy and breast-feeding, the need for L-carnitine can exceed production by the body. Therefore, L-carnitine is considered a "conditionally essential" nutrient

Answer 2

L-carnitine (levocarnitine), also known as carnitine is an amine derived from the amino acid lysine and is responsible for the transport of fatty acids from the cytosol into a cell's mitochondria. it is often sold as a nutritional supplement. originally found as a growth factor for mealworms and labled vitamin Bt. natural carnitine is the L-stereoisomer. it can be synthesised within the body from the amino acids lysine or methionine. vitamin C (ascorbic acid) is essential to the synthesis of carnitine. It has been speculated that during growth or pregnancy the requirement of carnitine could exceed its natural production.
fatty acids must be activated before they can be carried into the mitochondria, where fatty acid oxidation occurs. this process occurs in two steps, the formula for which is:
RCOO- + CoA + ATP + H2O → RCO-CoA + AMP + PPi + 2H+
this reaction is reversible and its equilibrium lies near 1. however, pyrophosphate is hydrolized by a pyrophosphatase, which drives the reaction forward, and to completion.
once activated, the acyl CoA is transported into the mitochondrial matrix. this occurs via a series of similar steps:

acyl CoA is conjugated to carnitine by carnitine acyltransferase I located on the outer mitochondrial membrane.
acyl carnitine is shuttled inside by a translocase
acyl carnitine is converted to acyl CoA by carnitine acyltransferase II located on the inner mitochondrial membrane. it is important to note that carnitine acyltransferase I undergoes allosteric inhibition as a result of malonyl CoA, an intermediate in fatty acid biosynthesis, in order to prevent futile cycling between beta-oxidation and fatty acid synthesis.

taurine or 2-aminoethanesulfonic acid is an acidic chemical substance found in high abundance in the tissues of many animals (metazoa), especially sea animals. taurine is also found in plants, fungi, and some bacterial species, but in far less abundance. it is an amine with a sulfonic acid functional group, but it is not an amino acid in the biological sense, not being one of the twenty protein-forming compounds encoded by the universal genetic code. small polypeptides have been identified as containing taurine, but to date there has been no report of a transfer RNA that is specifically charged with taurine.
the major pathway for mammalian taurine synthesis occurs in the liver via the cysteine sulfinic acid pathway. in this pathway, the sulfhydryl group of cysteine is first oxidized to cysteine sulfinic acid by the enzyme cysteine dioxygenase. cysteine sulfinic acid, in turn, is decarboxylated by cysteine sulfinic acid decarboxylase to form hypotaurine. it is unclear whether hypotaurine is then spontaneously or enzymatically oxidized to yield taurine.

Answer 3

They are amino acids.

Uhmmmm..... sumthing u can eat?
