Do carbohydrates have amino groups?

Answer 1

Amino acids have amine #(-NH_2)# groups in them, but carbohydrates do not. From the term, carbohydrates only contain carbon, hydrogen, and oxygen atoms, and they vary in shapes and sizes. Amine groups contain nitrogen in them, and carbohydrates do not have nitrogen in them, and so they cannot contain amine groups.

I hope this is useful.

Carbohydrates can have amino groups - but they generally have different functions that the regular "sugars" we think of.

Glucosamine, N-Acteyl Glucosamine, and Galactosamine are the sugars that make up posttranslational modification glycosylation groups; most cells display these sugars on their surface. Simple carbohydrates do not.

Although amino groups aren't found in starch, cellulose, etc., they are extensively utilized in cell-cell receptor sites and glycosylations on the cell surface.

The statement "anytime two cells interact, the interaction is almost always mediated by cell-surface sugars" is something I tell my biochemistry students. These sugars almost always contain amino groups.

Indeed, they do have them.

No, carbohydrates do not have amino groups. They consist of carbon, hydrogen, and oxygen atoms. Amino groups are found in amino acids, the building blocks of proteins.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
