During glycolysis, glucose is converted into :
Pyruvate
Glycolysis is the first stage of glucose breakdown and takes place in the cytoplasm. Through ten enzyme-controlled steps, one six-carbon glucose molecule is split into two three-carbon molecules of pyruvate (pyruvic acid).
The process gives a net gain of 2 ATP and 2 NADH, so ATP is a by-product rather than the product glucose is converted into.
Pyruvate then has two fates: with oxygen it enters the mitochondria and is converted to acetyl-CoA for the Krebs cycle; without enough oxygen it is reduced to lactic acid. Both acetyl-CoA and lactic acid are therefore formed after glycolysis, from pyruvate.
Hence, during glycolysis glucose is converted into pyruvate.

In eukaryotic cells, covalently attached lipids help to anchor some water soluble proteins to the plasma membrane. One group of cytosolic proteins are anchored to the cytosolic face of membrane by a fatty acyl group (e.g. myristate or palmitate).
