Discussion Overview

The discussion centers on the uses of lactose and galactose in humans, particularly regarding their solubility and physiological roles. Participants explore how lactose's low solubility can be beneficial and inquire about the functions of galactose beyond its role in gum production.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant questions how the low solubility of lactose can be beneficial for humans.
  • Another participant recalls that lactose may help control osmosis in certain cells, possibly aiding in the drying out of fecal matter in the colon.
  • There is mention of lactose being present in breast milk and its digestion by the enzyme lactase, which breaks it down into glucose and galactose for absorption.
  • Further inquiries are made about the potential role of lactose in the kidneys and its advantages in breast milk due to its low solubility.
  • Galactose is noted as a sugar that can be converted to glucose in the body, but its other uses in humans are not fully explored.
  • One participant expresses uncertainty about their earlier claims regarding lactose and withdraws their statement, indicating a lack of supporting evidence.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the specific uses of lactose and galactose, and multiple viewpoints regarding their physiological roles and benefits remain. The discussion includes both exploratory questions and some uncertainty about earlier claims.

Contextual Notes

Some claims regarding the role of lactose in osmosis and its functions in the kidneys are not substantiated with references, and the discussion reflects a mix of personal recollections and inquiries rather than established facts.

I would like to know the use of lactose and galatose in human with regarding to their solubility.
how does low solubility of lactose can be made good use on human?
what are the uses of galactose for human other than making guma?

Im not sure as to what the intent of your question is so maybe you can fill that part in. I remember refrences to lactose being used by some cells to control osmosis or rather to remove water by osmosis from other places, think it might have been the colon to dry out the fecal matter that was moving through it. Other wise they are both often used in breast milk by the body.

Lactose in found in milk. It is a di-saccharide (sugar ).Makes upto 2 to 8 percent of milk (by weight ).It is made up of glucose and galactose(monosaccarides).

The intestinal villi secrete an enzyme called lactase (β-D-galactosidase) to digest it. This enzyme cleaves the lactose molecule into its two subunits, the simple sugars glucose and galactose, which can be absorbed.

thanks for your reply.
you said lactose can be used to control osmosis, is that also happen in kidney?
what is the advantage of using lactose in breast milk with its low solubility property?
how about the galactose? what is the use of galactose in human?

hope to hear from you soon.

Lactose is broken down in the intestine into its components glucose and galactose which are absorbed.

kidneys contain a number of substances and no. of complex mechanisms for its function .

In the wiki link the lactose is formed in the body and secreted in breast milk.
All infants have the ability to break down this sugar - by the lactase enzyme secreted in the infants intestine.

galactose is another form of sugar which is can be converted to glucose in the body.

Just posting that after searching in my library and internetz all frigging weekend I havnt been able to back up my statement above and so I hearby withdraw it. Just wish I could remember the source cause in my head its clear as a bell. Oh well off to fall on my sword!
